Atomic number of an atom shows the number of protons in the nucleus of the atom. OR Atomic number of an atom is the number of electrons in the atom when the atom neutrally charged
Electronegativity
You think probable to atomic radius.
The electrongavitivity of an atom indicates an element is a part of electrons. The more electronegativity you have the more electrons you will need.
The valence indicate the type of a possible compound.
a prefix
Prefixes are used.
