false
Electrons that are further away from the nucleus have a greater attraction because the positive and negative charges are stronger than innermost electrons
Electron Shells
Valence electrons are those in the outermost shell of the atom.
the first shell: 2 electrons The second shell: 8 electrons The third shell: 18 electrons The fourth shell: 3 electrons
The innermost shell of every atom except hydrogen consists of 2 electrons.
Only 2 electrons can reside in the innermost shell.
false
false
no
Innermost is surely 2, as with every atom apart from Hydrogen?
Only in hydrogen or helium, because in these two elements only the innermost shell is also the outermost shell.
Electrons that are further away from the nucleus have a greater attraction because the positive and negative charges are stronger than innermost electrons
Electrons in the outermost energy shell (valence shell) have the most energy.
The innermost shell of any atom bigger than hydrogen (H) will contain 2 electrons.

The innermost shell of an atom is the shell corresponding to the principal quantum number of 1. Because the principal quantum number is 1, the angular quantum number and the magnetic quantum number of that shell must be 0. Therefore, only 2 electrons can possibly be in the innermost shell, one with spin up and the other with spin down.
