All atoms tend to fill their outer energy levels with the maximum number of electrons, usually eight. depending on whether atoms satisfy the octet rule will predict:

Explanation:

Octet rule is defined as the rule in which an atom in order to attain stability needs to have eight electrons in its outermost shell.

For example, atomic number of sodium is 11 and its electronic distribution is 2, 8, 1.

So, in order to acquire stability it just needs eight electrons in its outermost shell. Since, there is only one electron in its outermost shell and it is very difficult or impossible for a sodium atom to gain 7 electrons.

Therefore, it readily loses one outermost electron and becomes stable in nature.

This system of acquiring stability actually shows the chemical behavior of an atom or we can say that it shows reactivity of an atom.

Therefore, we can conclude that depending on whether atoms satisfy the octet rule will predict chemical behavior of the atoms.

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
