The carbon atoms can form a single unbranched chain, or the primary chain of carbon atoms can have one or more shorter chains that form branches. For example, butane C4H10 has two possible structures. In contrast, the condensed structural formula for isobutane is CH3 2CHCH3, in which the primary chain of three carbon atoms has a one-carbon chain branching at the central carbon.
Oxidation and Reduction When forming compounds, it is important to know something about the way atoms will react with each other. Oxidation numbers are assigned to atoms and compounds as a way to tell scientists where the electrons are in a reaction.
It is often referred to as the "charge" on the atom or compound. The oxidation number is assigned according to a standard set of rules. They are as follows: An atom of a pure element has an oxidation number of zero.
For single atoms in an ion, their oxidation number is equal to their charge. Fluorine is always -1 in compounds.
Cl, Br, and I are always -1 in compounds except when they are combined with O or F. The oxidation number of a compound is equal to the sum of the oxidation numbers for each atom in the compound.
Forming Ionic Compounds Knowing the oxidation number of a compound is very important when discussing ionic compounds. Ionic compounds are combinations of positive and negative ions.
They are generally formed when nonmetals and metals bond. To determine which substance is formed, we must use the charges of the ions involved. To make a neutral molecule, the positive charge of the cation positively-charged ion must equal the negative charge of the anion negatively-charged ion.
In order to create a neutral charged molecule, you must combine the atoms in certain proportions. Scientists use subscripts to identify how many of each atom makes up the molecule. To cancel these charges, we must have three magnesium atoms for every two nitrogen atoms:Sept Lesson - Atomic Theory -Atomic Number, Mass Number and Isotopes-Determining numbers of p, e, and n in atoms-Review of Bohr-Rutherford Diagrams and introduction to simplified Bohr Electron Arrangement Diagrams.
