First of all: telerium is not a correct name of an element.
Most probably is meant:
rather than:
Occupied (sub)levels are:
Te: [Kr] 4d10 5s2 5p4
(or Tb: [Xe] 4f9 6s2 )
The electron configuration of arsenic can be written as [Ar]4s^2 3d^10 4p^3. Therefor, 4p would be the highest occupied sub-level of an arsenic atom.

Sb (antimony)
Arsenic has 5 [valence electrons] in them.
As: Arsenic 33
As,Arsenic belongs to nitrogen family in periodic table so it has 5 valence electrons.

The chemical element arsenic, or As, is in group 15, period 4. Thus its electron configuration is 1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p3. Since its outermost shell is 4, arsenic has 5 valence electrons.

Arsenic has 5 [valence electrons] in them.
Antimony (Sb, # 51) has 5 valence electrons (and so do all the other elements in that group.)
As: Arsenic 33
To determine this look at the periodic table. The larger the atom, the farther its valence electrons are from the nucleus. Therefore, potassium's valence electrons have the highest energy.
