- Atomic number is equal to the number of protons
- Atomic number is equal to the number of electrons (in a neutral atom)
- Atomic number is the number of a chemical element in the Periodic Table of Mendeleev
Yes

The number of protons in the nucleus of an atom positively identifies the element of which the atom is an example, whether the atom is neutral or ionized.
Yes.

Atoms are normally identified according to the element of which that atom is an example. And that, in turn, is determined by the number of protons in the atom's nucleus. So, any atom that has just one proton is a hydrogen atom. If it has two protons it is a helium atom. And so forth.

One can identify the hybridization of an atom in a molecule by looking at the number of electron groups around the atom. The hybridization is determined by the combination of atomic orbitals that overlap to form these electron groups. The most common hybridization states are sp, sp2, and sp3, which correspond to different numbers of electron groups around the atom.
