A chemical <b>compound</b> is a chemical substance composed of many identical 
molecules (or molecular entities) composed of atoms from more than one 
<b>element</b> held <b>together</b> by chemical bonds. Two atoms of the same <b>element</b> 
bonded in a molecule do not <b>form</b> a chemical ... A <b>compound</b> can be converted to 
a <b>different</b> chemical composition by&nbsp;... A combination reaction is a reaction where two or more <b>elements</b> or <b>compounds</b> (
reactants) <b>combine</b> to <b>form</b> a single <b>compound</b> (product). Such reactions may be 
represented by equations of the following <b>form</b>: X + Y → XY. The combination of 
two or more <b>elements</b> and <b>form</b> one <b>compound</b> is called ... In such a situation, 
<b>different</b> quantities of each reactant must be used. Steam and liquid water are two <b>different forms</b> of the same chemical substance, 
water. A chemical substance is a <b>form</b> of matter having constant chemical 
composition and ... All matter consists of <b>various elements</b> and chemical 
<b>compounds</b>, but these are often intimately mixed <b>together</b>. Mixtures contain more 
than one&nbsp;... A chemical <b>element</b> is a species of atom having the same number of protons in 
their atomic ... A single <b>element</b> can <b>form</b> multiple substances differing in their 
structure; they ... the atoms held <b>together</b> by chemical bonds, they <b>form</b> chemical 
<b>compounds</b>. ... <b>Different</b> isotopes of a given <b>element</b> are distinguished by their 
mass&nbsp;... All other diatomic molecules are chemical <b>compounds</b> of two <b>different elements</b>. 
Many <b>elements</b> can <b>combine</b> to <b>form</b> heteronuclear diatomic molecules,&nbsp;... In chemistry, the valence or valency of an <b>element</b> is a measure of its <b>combining</b> 
power with other atoms when it <b>forms</b> chemical <b>compounds</b> or ... The two tables 
below show some examples of <b>different compounds</b>, their ... The prefix co- means 
&quot;<b>together</b>&quot;, so that a co-valent bond means that the atoms share a valence. The oxidation state of oxygen is −2 in almost all known <b>compounds</b> of oxygen. 
The oxidation ... Oxygen is reactive and will <b>form</b> oxides with all other <b>elements</b> 
except the noble gases helium, neon, argon, and krypton. ... Peracetic acid (
feeder material for <b>various</b> epoxy <b>compounds</b>) is obtained from acetaldehyde: CH 
3CHO +&nbsp;... In chemistry, the law of multiple proportions states that if two <b>elements form</b> more 
than one <b>compound</b> between them, then the ratios of the masses of the second 
<b>element</b> which <b>combine</b> with a ... For example, Dalton knew that the <b>element</b> 
carbon <b>forms</b> two oxides by <b>combining</b> with oxygen in <b>different</b> proportions. A 
fixed&nbsp;... In chemistry, catenation is the bonding of atoms of the same <b>element</b> into a series
, called a chain. A chain or a ring shape may be open if its ends are not bonded 
to each other (an open-chain <b>compound</b>), ... Carbon chains in biochemistry 
<b>combine</b> any of <b>various</b> other <b>elements</b>, such as hydrogen, oxygen, and 
biometals, onto&nbsp;... John Dalton FRS was an English chemist, physicist, and meteorologist. He is 
best known for ... Atoms of <b>different elements combine</b> in simple whole-number 
ratios to <b>form</b> chemical <b>compounds</b>. In chemical reactions ... So, one atom of 
<b>element</b> X <b>combining</b> with one atom of <b>element</b> Y is a binary <b>compound</b>. 
Furthermore, one&nbsp;...
