Innermost electrons are located closer to the nucleus of an atom, in energy levels closest to the nucleus. These electrons have lower energy and are usually referred to as core electrons.
The innermost shell of every atom except hydrogen consists of 2 electrons.
Innermost is surely 2, as with every atom apart from Hydrogen?
there are 2 electrons in potassium's innermost energy level
Argon has 18 core electrons. This is because it has 18 electrons in total, and the core electrons are the innermost electrons that are not involved in chemical bonding.
The group number 17 comprises of elements that has seven electrons in their own outer level.

Only 2 electrons can reside in the innermost shell.

Electrons located in the innermost energy levels (such as the 1s level) have the lowest energy. These energy levels are closest to the nucleus and are filled first in an atom according to the aufbau principle.
Argon has 18 core electrons. This is because it has 18 electrons in total, and the core electrons are the innermost electrons that are not involved in chemical bonding.
The group number 17 comprises of elements that has seven electrons in their own outer level.
Helium has 2 core electrons. This is because it has 2 electrons in the innermost energy level (K shell), which are considered core electrons.
