Only 2 electrons can reside in the innermost shell.
The innermost shell of every atom except hydrogen consists of 2 electrons.

false
The innermost shell of an atom, also known as the K shell, can hold a maximum of 2 electrons. This is based on the formula (2n^2), where (n) is the principal quantum number of the shell. For the K shell, (n=1), so (2(1^2) = 2). Thus, only 2 electrons can occupy this shell.
Innermost is surely 2, as with every atom apart from Hydrogen?
The number of electrons that can occupy each shell in an atom is determined by the formula 2n2, where n is the shell number.
no
The very inner shell of an atom is the 1st shell and can only contain 2 electrons.
The innermost shell of an atom, also known as the K shell, can hold a maximum of 2 electrons. This is determined by the formula (2n^2), where (n) is the principal quantum number of the shell. For the K shell, (n = 1), so (2(1^2) = 2). Therefore, there are 2 places for electrons in the innermost shell.
The second shell can hold eight electrons.
Only in hydrogen or helium, because in these two elements only the innermost shell is also the outermost shell.
The first shell of an atom can hold a maximum of 2 electrons.
