8 so then it is an Octet.
Noble gases are very stable because their outermost electron shells contain the maximum number of electrons that those outermost shells can possess. This is a correct statement. Yes.
The smallest particle of an element would be an atom. Any smaller and it would not be an element, but something more basic. Atoms are made of Protons, Neutrons, and Electrons. Protons and Neutrons are made of Quarks, Leptons, and Bosons.
No. Electrons possess a negative charge, therefore an atom with an excess of electrons will have an overall negative charge.
4 electrons. First orbital is the 1s which has 2 electrons. Second orbital is the 2s which has 2 electrons.
There are 7 different f-orbitals and each orbital can hold 2 electrons.
protons and electrons
It would be a group 6 element posessing 8 electrons in the outermost shell but the total number would depend on which element it was.

Ionization stepIonization energy ()101219032912495662732223325997 for this chart, the greatest increase was from E_15 to E_16. therefore 5 electrons are in the valence shell
those elements which can donate two electrons will possess plus two oxidation state like calcium , magnesium ,etc...
2
A barium atom has two valence electrons.
Isotopes of an element are the same in that they are both forms of the same element. All carbon isotopes, for example, are forms of the carbon atom. Each isotope will possess the same number of protons and electrons (equivalent to the element's atomic number). However, isotopes of an element possess different numbers of neutrons, altering their atomic mass. As such, if you know the atomic mass (or weight) of a given isotope, you already know the number of protons and electrons. Using the measured mass of the proton (around 1.007 amu) and the measured mass of the electron (around 0.00055 amu), you can determine the remaining mass from the neutrons and, consequently, the number of neutrons.
Carbon
Gallium possess total inner electrons
Phosphorus (neutral atom) has 15 electrons.
