the number of protons in an element is called the atomic number and there is no way to see how many electrons an element has.
valence electrons
All atoms of an element have same no. of electrons and protons. Hence, Atomic no. is given as no. of electrons or no. of protons.
All atoms have the same number of protons and electrons, but an atom with a different number of protons and neutrons is called and isotope
That is called an ion.

The number of electrons should equal the number of protons, otherwise you have an ion.

valence electrons
If the number of protons and electrons are not equal, the atom becomes a charged particle called an ion.
On average, in any atom, you will have the same number of electrons and protons.

All atoms have the same number of protons and electrons, but an atom with a different number of protons and neutrons is called and isotope
An ion. If there are less electrons than protons, the atom gains a positive charge and is called a cation. If there are more electrons than protons, the atom gains a negative charge and is called an anion.
the atomic number (this is also the number of protons)
That is called an ion.
The number of protons and electrons in the atom. If the number of protons = number of electrons, it is electrically neutral. If number of protons > number of electrons, it is positively charged. If number of protons < number of electrons, it is negatively charged.
