The number of valence electrons in each atom of an element affects the elements

The number of electrons in an atom's outermost valence shell governs its chemical properties. Elements react to form a closed shell, corresponding to the electron configuration s2p6 . This tendency is called the octet rule, because the atoms have eight valence electrons.

Explanation:

The number of valence electrons or outermost electrons present in an atom determines the chemical properties of an atom.

Therefore, atoms belonging to same group have same number of valence electrons. Thus, atoms of a group have similar chemical properties.

Hence, we can conclude that the number of valence electrons in each atom of an element affects the elements chemical properties.

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 .

can you list the answers so i can answer
