I think you mean what are the main parts of a chemical atom. There are three particles: protons (which have a positive charge), electrons (a negative charge) and neutrons (no charge).
H2O is water. There is no chemical name for it. Water is two hydrogen atoms covalently bonded to a single oxygen atom.
It is a chemical name for Beryllium Nitride.
a formula equation
The same number you started with. In every chemical reaction the total number of atoms at the start is the same as the number of atoms at the end.
Atoms of different elements unite during chemical changes to produce at least one chemical compound.
Trioxygen or O3 3 Oxygen atoms.
These particles are atoms.
Covalent Bonding
This is a covalent bonding.
H2O is water. There is no chemical name for it. Water is two hydrogen atoms covalently bonded to a single oxygen atom.
When a chemical reaction occurs atoms get ionized. Atoms are never created nor destroyed in a chemical reaction.
Many compounds have the chemical formula C6H14; the most common is hexane.
It is a chemical name for Beryllium Nitride.
No, this would be contrary to the definition of an ordinary chemical reaction.

Prefixes in chemical names indicate the number of atoms of each element present in the molecule before the main part of the name. They provide information about the composition and structure of the compound.
