what is the big deal about chemistry?

without it we wouldn't understand global warming, how to stop it, how to create medicines. we wouldn't understand how water is made.\n\nwith out science we know nothing and will be DEAD as DOORNAILS which wouldn't be invented without chemistary and the knowledge if bonding 2 metals or more chemically

This is a difficult part of chemistry, but you'll get it if you just keep going over it - really slowly. Also ask your teacher for help, get a tutor, or get together with a group of your classmates.\nYou should do all of this before looking at a website because it could just confuse you more and have more details than you need to know. \nHere is a website you can check out.

Every where chemica reactions occur to regulate life processes, within your body millions of chemical reactions happen within a second so that you are able to function. Put that on a more macro scale say the environment, everything from water breakdown, decomposition, geologic formation, life cycles, etc are all governed by chemistry. Suffice to say that life would not be possible unless chemistry is relevant and working.

The most important concept of organic chemistry is "the interaction of filled and empty orbitals is stabilising!" Keep that in mind and you will be fine.

Chemistry because chemistry rocks. Seriously though, in my opinion, chemistry is a lot more fun because you get to make stuff. Also if you may find that you'll be able to take up computational chemistry and use PC etc to model chemical reactions, molecules or simulate spectra.\n\nChemistry all the way for me.

True any chemical produced or sold in huge quantities such as several liters are called bulk chemicals. It has nothing to do with the type of chemical but in the quantity that is ordered or bought.

It is a science. Trying to understand how things works, through observation and logical analysis. It is less precise or clear-cut than physics or chemistry, but that's because the subject matter keeps changing.

CHEMISTRY I: ATOMS AND MOLECULES\nTable of Contents\nAtoms | Electrons and energy | Chemical Bonding | Chemical reactions and molecules\n\nLearning Objectives | Terms | Review Questions | Links\nAtoms | Back to Top\n\nMost of the Universe consists of matter and energy. Energy is the capacity to do work. Matter has mass and occupies space. All matter is composed of basic elements that cannot be broken down to substances with different chemical or physical properties. Elements are substances consisting of one type of atom, for example Carbon atoms make up diamond, and also graphite. Pure (24K) gold is composed of only one type of atom, gold atoms. Atoms are the smallest particle into which an element can be divided. The ancient Greek philosophers developed the concept of the atom, although they considered it the fundamental particle that could not be broken down. Since the work of Enrico Fermi and his colleagues, we now know that the atom is divisible, often releasing tremendous energies as in nuclear explosions or (in a controlled fashion in) thermonuclear power plants.\n\nSubatomic particles were discovered during the 1800s. For our purposes we will concentrate only on three of them. The proton is located in the center (or nucleus) of an atom, each atom has at least one proton. Protons have a charge of +1, and a mass of approximately 1 atomic mass unit (amu). Elements differ from each other in the number of protons they have, e.g. Hydrogen has 1 proton; Helium has 2.\n\nThe neutron also is located in the atomic nucleus (except in Hydrogen). The neutron has no charge, and a mass of slightly over 1 amu. Some scientists propose the neutron is made up of a proton and electron-like particle.\n\nThe electron is a very small particle located outside the nucleus. Because they move at speeds near the speed of light the precise location of electrons is hard to pin down. Electrons occupy orbitals, or areas where they have a high statistical probability of occurring. The charge on an electron is -1. Its mass is negligible (approximately 1800 electrons are needed to equal the mass of one proton).\n\nThe atomic number is the number of protons an atom has. It is characteristic and unique for each element. The atomic mass (also referred to as the atomic weight) is the number of protons and neutrons in an atom. Atoms of an element that have differing numbers of neutrons (but a constant atomic number) are termed isotopes. Isotopes can be used to determine the diet of ancient peoples by determining proportions of isotopes in mummified or fossilized human tissues. Biochemical pathways can be deciphered by using isotopic tracers. The age of fossils and artifacts can be determined by using radioactive isotopes, either directly on the fossil (if it is young enough) or on the rocks that surround the fossil 9for older fossils like dinosaurs). Isotopes are also the source of radiation used in medical diagnostic and treatment procedures.\n\nNote that each of these isotopes of hydrogen has only one proton. Isotopes differ from each other in the number of neutrons, not in the number of protons.

Other isotopes are stable. Examples of radioisotopes are Carbon-14 (symbol 14C), and deuterium (also known as Hydrogen-2; 2H). Stable isotopes are 12C and 1H.\n\nCarbon has three isotopes, of which carbon-12 and carbon-14 are the most well known.

An on-line Periodic Table is available by clicking here, or if that is busy try a mirror site.\n\nThe Periodi

You might be looking for information on alchemy, not chemistry.  The two fields of study are very seperate these days.  Of course, modern scientits could turn lead into gold by nuclear fusion, or turn heavier elements into gold by fission- neither process seems practical.

Chemistry really started to be differentiated from alchemy in the 1650s and 60s by an Irish gentleman name Robert Boyle.  His work _The Sceptical Chymist_, which is seen today as the cornerstone of modern chemistry, took the concepts of late alchemy and the methodical reasoning of early physics and combined them into an entirely new discipline.

First of all, do you know what a molecule is?\n\nA molecule is the smallest particle of a substance (that still has the same chemical and physical properties of the substance) that is composed of 2 or more atoms.  Atoms are held together by a number of chemical forces, including a wide variety of bonds.\n\nAn inorganic molecule is a molecule from a substance that is non-living.  It is not composed of organic (living) matter, and often times that means it will not contain carbon, as carbon (C) is the main element of organic molecules.

You do need it. Maybe not the way you get it in high school but electricians deal with chemistry in many ways. \n\nHere are a few: batteries -- how they work, how they charge and discharge, the worry about them, etc. are all chemistry\n\nChemistry deals with corrosion: a big deal with connections, wiring. \n\nFuel cells -- another chemical operation\n\nHazardous materials -- chemistry deals with how to read the MSDS (safety sheets) of all the chemicals you deal with in being an electrician\n\nIt may not be required, but it is a good bit of knowledge you may need to pick up somewhere.

Imagine life without chemistry....we are surrounded by chemistry! start looking around you and you'll see why chem is so important. the chemical industry produces materials that are vital to the industrialized world. Everything that you use at home are the products of chemistry, even your cosmetics. Imagine how will your breakfast turn into energy without the chemistry.

You can get the basics out of any encyclopedia , I did way back in high school , 1965 . Built a model for Chemestry class , got an A+ .\nThe 2 problems are getting and refining the fizzable materials .\nThe rest is just another bomb .
