If the p orbital is half filled, then it would have 3 electrons. So, look for the third p-block element in the 5th period. That turns out to be antimony (Sb).
Xe
It could be either Indium or Iodine.
Gallium is the element has three electrons in energy level n = 4.
The energy level of an element is what Period it is in. For example, berylium is in Period 2, so that means it has 2 energy levels.
The valence electrons are the outer most electrons and the principal energy level in which they belong will vary for element to element and generally corresponds to the period number in which the element is present
Xe
Sb (antimony)
It could be either Indium or Iodine.
5s^2 5p^2 is the valance count and a little work, and knowledge of the periodic table will tell you this element is, tin Sn
6(5p)=30p
5p+5p
if question isHow many 5p's are in £22 x 5p = 10p20 x 5p = 100p = £140 x 5p = 200p = £2Answer: forty
sixty2 x 5p = £0.1020 x 5p = £1.0040 x 5p = £2.0060 x 5p = £3.00
20 x 5p = £1 200 x 5p = £10 2,000 x 5p = £100
5p + 15p + 7p = 27p 5p - 15p + 7p = -3p 5p x 15p + 7p = 75p2 + 7p 5p/15p + 7p = 7p + 1/3
25 * 5p = 125p
The GCF is 5p.
