A filled highest occupied principal energy level
The atomic number of zinc is 30. Its abbreviated electron configuration is [Ar]4s23d10 The full electron configuration is 1s22s22p63s23p64s23d10 (configurations for the atom in its ground state. Ions and excited atoms have different configurations).
The electron configuration of gallium is 1s22s22p63s23p64s23d104p1 The shorter version is [Ar]4s23d104p1
The electron configurations of all the elements in a group have the same number of valence electrons. Valence electrons are the electrons found in the outermost shell of an element.
All alkaline earth metals have electron configurations ending in s2; 6s2 would be the alkaline earth metal in period 6 of the PTE, which is barium.
It has a full outer shell of electrons.

This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Each element has a specific electron configuration, causing each to have a distinctive color when exposed to fire
Is nickel active or inactive
The standard model suggests an electron cofiguration for nickel (element number 28)as :[Ar] 4s2 3d8However, relativistic effects make the more stable configuration [Ar] 4s1 3d91s2,2s2,2p6,3s2,3p6,4s2,3d8
The electron configuration of gallium is 1s22s22p63s23p64s23d104p1 The shorter version is [Ar]4s23d104p1

The simplest element from an atomic structure point of view is hydrogen with just one proton and one electron. Its chemistry is by no mean simple!
elements only have a charge when they are ionised and all ionised elements are much heavier than an electron I think you mean which sub-atomic particle has a positive charge and is relatively heavy compared to an electron This is the proton.
Atoms of the element selenium (atomic number 34) have the electron configuration 1s2, 2s2, 2p6, 3s2, 3p6, 4s2,3d10, 4p4
The electron configurations of all the elements are well-known and can be looked up in tables. They were originally determined by studying the characteristic light spectra emitted by atoms of the elements and found to be in agreement with the predictions made by quantum mechanics.
