Two electrons can occupy the 2s subshell, and 8 electrons can occupy the 3d subshell.
Sc is a 3d element. It has 21 protons and 21 electrons.
2 electrons in the K shell and 8 electrons in the L shell
Potassium ion has 18 electrons.
None. Zinc fills up its 3d sublevel with 10 electrons, all pairs. So, there are no remaining unpaired electrons
Potassium (K) is atomic number 19. It has 19 electrons.1s2 2s2 2p6 3s2 3p6 4s1 so it has ZERO 3d electrons. The 3d doesn't receive electrons until you reach scandium (atomic number 21).
Zinc has ten 3d electrons.
3d10 Ten electrons is the maximum number of electron in 3d.
There are a maximum of 10 electrons in the 3d sub-level.
The 3d subshell is completely filled in Arsenic. Therefore it has 10 electrons.
3d^6 Six electrons in the outer shell.
Two electrons can occupy the 2s subshell, and 8 electrons can occupy the 3d subshell.
10
Titanium has two electrons in its 3d sublevel.
One Mn atom contains 5 electrons in it's 3d subshell, all of which are unpaired.
The K shell of an atom can hold up to 2 electrons.
An electric-neutral K atom has 19 protons and 19 electrons.
