Iam in 10th grade. so can u tell me which compounds' properties are necessary for me to learn.?

u should instead study the properties of different types of compounds like metals, covalent compounds, ionic, macromolecular. then go on to the types of bonds which will explain their physical properties. then apply what u learn to any compund u come across.

1. electron\n2. ionic\n3. molecules of compounds\n4. decomposition (not sure)

um...  subtract???  hahaha\n\nThe higher the differences in electronegativity, the more ionic the compound.  The higher electronegative atom/ion will want to "hog" all the electrons.  They are greedy like that.  They don't want to share (which would be a covalent bond).

Say goodbye to matter, I suppose.\n\nWithout electrons (which are negative), all chemical bonds would collapse - so definitley say goodbye to any and all compounds. There goes most materials.  Ditto for chemistry.

Chemistry is a subject of memory and conception. One requires knowledge of mathematics and physics to tackle physical chemistry.Inorganic Chemistry requires memory, reasoning capabilities and logical skills.Organic Chemistry require good knowledge of almost the whole of Physical and Inorganic if you go to learn mechanisms and far deep.Good Conceptual study can reduce a lot of labour and time wasted in studying like a parrot. Practicals should accompany theory as it helps in good understanding.

The question is not clear.  Are you asking what a crystal is?  Are you asking what the different crystal structures are?  Are you asking for the characteristics of crystals in general?

Chemical properties are properties such as boiling point, freezing point, melting point, electronegativity, flammability, and so forth.  Physical properties are the ones the human senses can pick up with out having to change the chemical, such as taste, smell, sound.

Acids & bases is pretty easy to understand. You could probably find quite a bit of stuff too, about their properties, indicators, things they're used for, all that stuff. Or you could try energy. It may be a little harder, but you could go on forever about energy. What types of energy there are (thermal kinetic, mechanical kinetic, radient, gravitational potential, electrical potential, chemical potential), how energy changes between forms, pahses changes in matter (because of energy), on and on and on. Hope that helps.

a phd student in chem looking for basic chem material on the web.\n\nright.\n\nstart here: http://www.carleton.ca/~rburk/chem1000\n\na textbook might also be useful.

I'd suggest a thorough understanding of chemistry and physics. You need to know trajectory and what to mix with what to get the different colors.

d) bond to carbon\n\nThis nonmetal has the interesting chemical property of being able to bond with itself and a wide variety of other elements, forming nearly ten million known compounds.

Rote memorization, with flashcards possibly, is the only way I can think of. Like the other poster said, look for carbonyls, alcohols, alkenes, and amino peaks (a weak, wide peak at about ... 3200 or so)

oxygen, nitrogen, every fuckin mineral and more on the periodic table...take chemistry

Need more info in order to help you...what class level?...what field of chem?...writing project or lab demo?...what is an 'investigatory project'?\nPlease resubmit your question anew with as much info as possible so that we can offer reasonable suggestions...if you simply edit this one we cannot reply twice to same question.

Try doing a Google search under the Hall or the Hall-Heroult process.    That or check out a General or an Inorganic Chemistry book from the library.  That's a good launch point.

It depends on what you mean by "properties."  Mass is determined by the number of protons & neutrons in the nucleus.  That also relates to melting point and boiling point, though other factors affect those, too.  But the CHEMICAL properties are determined by the electrons, and specifically, the electrons in the outer shell (and next to outer shell, for the transition elements).  It's those electrons that determine if an element is a metal or nonmetal, what elements it will form bonds with, how reactive it is, etc.

well family 13 has B and Al.  they are metaloids that are great lewis acids.  they have interesting bonding strategies that defy the normal octet rule.
