The tiniest particle of a chemical element is called an atom.
Sodium chloride is formed.
Atomic number is about protons. It symbolises the protons an atom has.
You could describe it as neutral as the charge of the protons cancels out the charge of the electrons, essentially though it is just a normal atom as if the number of protons was different to the number of electrons, it would be classed as an ion.
The number of protons in the nucleus of an atom
It describes it because it is atom model and it had a nucelus, protoins and electrons

When an atom loses an electron it becomes positively charged.
It is the part of the atom with the greatest mass
The number of protons in the nucleus of an atom
The term nucleus is used to describe the center of something, usually an atom or a cell; it could be used to describe the center of a city as well.
A parent atom is a term used to describe the original state of an atom or element before it undergoes a chemical change. For instance, it may be used when discussing radioactive decay. The original element would be the parent atom, and the element that results from the radioactive decay would be the daughter atom. It may also be used when discussing ions. The parent atom would be the element before it undergoes ionization, and the daughter atom would be the resulting cation or anion.
Smallest unit of matter that is indivisible.
A water molecule has a single Oxygen atom bound to two Hydrogen atoms at approximately 120o. Think of Mickey Mouse's head - his face would be the Oxygen atom, and his ears would be the Hydrogen atoms.
