I'm not sure, but why don't you include a quote from the teacher or the book using these terms?  I'm sure putting them in context would help with identifying them.

The answer befor this one is good and the reference coaded is informative but add to make concepts clear:\n\nThe term Representative Element is used in the perspective of Periodic Table.\n\nA representative element means an element to represent characteristic properties of a group (also known as family) of elements in the Periodic Table.\n\nCharacteristics of a group of elements include: the outer orbital s, p, d, f; the number of electrons in the outer orbital, the chemical properties, the types of chemical bonds formed etc.\n\nHe, Li, Be, B, C, N, O and F are the representative elements.\n\nH is not considered as representative element because it is though usually placed at the top of 1st group (Li family) it is also considered for placement in C family and Halogens.

Dear Lord,\n\nPlease help me circle the wagons!  There is no parallel for my situation.  I'm surrounded by squares who will ace this test and I forgot to study a segment.  Be my ray of light, beaming through a kite of confusion.  Send down your angles to assist me.  I need points on this test.  Please, send me a sine.

well chemistry is what happens between two people if they really love each other you see when a boy loves a girl, the 3fd element on the priodic table comes in... literally lol you see if two people have great chemistry they make babies which is were tha math come is... not literally this time . using the math you can count the babies 1...2...3 and thats the facts about chemistry!

http://periodic.lanl.gov/default.htm\n\nClick on the element, and it's in the top section of information. To write out the electron configuration for every element would take quite a while, so if you need it for a specific element or a few elements, I'd reccomend asking just for the few.

Basically what this is referring to is the ionization of the atoms you have listed. this occurs when there is a shift in the distribution of the electron in the various bands 'orbiting' the nucleus of the atom, or a proton has been added to the nucleus. \n\nWhat the statement seems to be refering to is the creation of a positive ion (cation). If this is to occur it needs a shift in the distribution of the electrons in the shells. To move an electron from one band to another, or to excite one enough to be lost fully from orbit you will need a level of energy. \n\nIn the cases stated, I would say that 3.1eV is the minimum energy required to create a transition of an electron between the bands or to lose an electron and so create the ion. \n\nHope that helps.

All kinds of things. All of a cars mechanisms are based on physical laws. I suppose this is for a school project so it might be enough if you talk about speed, acceleration etc...and maybe about the chemical energy that is being converted to heat energy which is being converted to kinetic energy (in school terms). When going through a curve you can talk about centripetal acceleration etc etc

ATOM..basic building block\n \n[Gr.,=uncuttable (indivisible)], basic unit of matter; more properly, the smallest unit of a chemical element having the properties of that element.  That is the definition.  Continue to read further; it really gives great detail!!!!!\n\nStructure of the Atom\n\nThe atom consists of a central, positively charged core, the nucleus, and negatively charged particles called electrons that are found in orbits around the nucleus.\n\nThe Nucleus\n\nAlmost the entire mass of the atom is concentrated in the nucleus, which occupies only a tiny fraction of the atom's volume. The nucleus of an atom consists of neutrons and protons, the neutron being an uncharged particle and the proton a positively charged one. Their masses are almost equal. Atoms containing the same number of protons but different numbers of neutrons represent different forms, or isotopes, of the same element.\n\nThe Electrons\n\nSurrounding the nucleus of an atom are its electrons; for a neutral atom, the number of electrons is equal to the atomic number. The outermost electrons of an atom determine its chemical and electrical properties. An atom may combine chemically with another atom in various ways, either by giving up or receiving electrons, thus setting up an electrical attraction between the atoms (see ion), or by sharing one or more pairs of electrons (see chemical bond). Because metals have few outermost electrons and tend to give them up easily, they are good conductors of electricity or heat (see conduction).\n\nThe electrons are often described as revolving about the nucleus as the planets revolve about the sun. This picture, however, is misleading. The quantum theory has shown that all particles in motion also have certain wave properties. For a particle the size of an electron, these properties are of considerable importance. As a result the electrons in an atom cannot be pictured as localized in space, but rather should be viewed as smeared out over the entire orbit so that they form a cloud of charge. The electron clouds around the nucleus represent regions in which the electrons are most likely to be found. The shapes of these clouds can be very complex, in marked contrast to the simple elliptical orbits of planets. Surprisingly, the sizes of all atoms are comparable, in spite of the large differences in the number of electrons they contain.\n\nAtomic Weight and Number\n\nThe atomic number of an atom is simply the number of protons in its nucleus. The atomic weight of an atom is given in most cases by the mass number of the atom, equal to the total number of protons and neutrons combined. An atom may be conveniently symbolized by its chemical symbol with the atomic number and mass number written as subscript and superscript, respectively. For example, the symbol for uranium is U (atomic number 92); the isotopes of uranium with atomic weights 235 and 238 are indicated by 23592U and 23892U.\n\nDevelopment of Atomic Theory\n\nEarly Atomic Theory\n\nThe atomic theory, which holds that matter is composed of tiny, indivisible particles in constant motion, was proposed in the 5th cent. by the Greek philosophers Leucippus and Democritus and was adopted by the Roman Lucretius. However, Aristotle did not accept the theory, and it was ignored for many centuries. Interest in the atomic theory was revived during the 18th cent. following work on the nature and behavior of gases (see gas laws).\n\nFrom Dalton to the Periodic Table\n\nModern atomic theory begins with the work of John Dalton, published in 1808. He held that all the atoms of an element are of exactly the same size and weight (see atomic weight) and are in these two respects unlike the atoms of any other element. He stated that atoms of the elements unite chemically in simple numerical ratios to form compounds. The best evidence for his theory was the experimentally verified law of simple multiple proportions, which gives a relation between the weights of two elements th

I will get you started on the exact answers to this, my friend.  But I am not going to do all your work for you.\n\nGo to http://myweb2.search.yahoo.com/search?fr=ks&p=paramagnetic+elements \n\nOnce you pull that up and start reading, it will lead to all the rest fairly directly.\n\nBe sure to groove on each definition to get the exactitude of it -- magnetic, paramagnetic, diamagnetic, etc.\n\nTry to learn something about the electron configurations involved.\n\nAll good things take some work, you will learn better if you do it yourself while taking notes.

In the formation of a molecule only the outer shell electrons are involved and they are known as valence electrons.It is, therefore, quite reasonable to consider these valence electrons while discussing chemical bonds and other chemical properties as the case may arise.\n          G.N.Lewis introduced simple symbols to denote valence electrons in an atom.The outer shell electrons are shown as dots surrounding the symbol of the atom. These symbols ignore inner shell electrons. This type of representation is known as Lewis dot representation.Structures of molecules denote by this representation is called Lewis dot structure. \n The common valency of the element is either equal to the dots in Lewis symbol (if less than equal to 4) or 8 minus these dots (if these are more than 4)\n\nFor examples of dot structures click the following link:\nhttp://img106.imageshack.us/img106/3875/untitled1ju.jpg

the amount of electrons in an atom.\n\nif you're going to use noble gas configuration, you would use the noble gas and then continue the configurations.\n\nex. i want the configuration of... flourine (F)\nfor noble gas configuration i would say: (He) 2s 2 2p 6\n\nthe parenthasese is actually a bracket, and the numbers that are spaced should be in the upper righthand corner of the letter before it.

Here is what I got\nhttp://img.photobucket.com/albums/v628/kerahna/lewis.jpg\n\nPretend the Xs are all dots. I just draw Xs to keep track of which electron belongs to which atom. They are all the same.\nI haven't checked the formal charges yet, I'm going to do that now.\n\nEDIT: The formal charges are good.

Hey man..ask both the questions together.Anyways now i will explain you both. Here t means triplet. It means three similar energy orbitals. Others are\nA=Singlet\nE=Doublet\nT=triplet\n\nAlso 2 here dentoes symmetry about the center. i.e 2 are centrosymmetric while one are no. e.g p orbitals being centro symmetric fall in 2 case and sp3 hybrid orbitals fall in 1 case!!

s,p,d,f are the names of different kinds of electron orbitals.  they correspond to different values for the angular momentum quantum number "l".  \n\ngoing from s -> p -> d -> f and so on means an increase in the electron's angular momentum about the nucleus.  s means the l quantum number is 0; p means l = 1, d means l=2, f means l=3.  \n\nrereading the question, maybe you mean what do the letters stand for?  it has to do with the way electron orbitals are studied, which is via emission spectroscopy.  the names were originally given to describe different kinds of spectral lines and they stand for:  sharp, principal, diffuse, and fundamental.
