How Many Electrons Can Go In The First Shell. When there are no excited electrons, energy levels fill up innermost to outermost. How many electrons will go in the second energy level of the carbon atom?

Ozair pointed out that the 5s, 5p subshells are filled before the 4f subshell gets filled, but did not give the reason. How many electrons can go in the first shell? How many electrons does each element require in its valence shell to become stable?
How Many Electrons Are In A Shell?
It is called the 1s orbital because it is spherical around the nucleus. There are 2 electrons in excited states, the ones in the third energy level. A carbon atom has six electrons.
The Third Shell Can Carry Up 18 Electrons, But It Is More Stable By Carrying Only Eight Electrons.
Most elements that are essential in chemistry require eight electrons in each shell to be stable. When there are no excited electrons, energy levels fill up innermost to outermost. The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on.
The First Shell Can Hold Up To Two Electrons, The Second Shell Can Hold Up To Eight (2 + 6) Electrons, The Third Shell Can Hold Up To 18 (2 + 6 + 10) And So On.
However, some atoms can be stable with eight electrons, even though their valence electrons are in the 3n shell (which can hold up to 18 electrons), so it depends on the element. 2 in the first orbit 8 in the second and third ring 18 in the fourth etc. A calcium atom has 20 electrons….electron shells.
6 In Three 3P Orbitals;
Antimony is a metalloid protons: Because the first shell can only hold a maximum of 2 electrons, the third electron must go into the second shell. 2 in a 2s orbital and 6 in three 2p orbitals.
The Third Shell Holds 18 Electrons;
This first shell has only one subshell (labeled 1s) and can hold a maximum of 2 electrons. Okay, now let's apply all of this to an example. Then the fourth shell begins to fill….electron shells.
