Elements with three p-electrons....
That would be N, P, As, Sb, and Bi -- elements in group 15
For example, energy diagram showing "empty" orbitals up through the 3p.

According to Hund's rule, the electrons singly occupy the p-orbitals, and all have the same spin.
Answer:
Exit velocity of air is 96.43 m/s.
Explanation:
Given that
For air
Now from first law of thermodynamics for open system at steady state
For diffuser
We know that
So the exit velocity of air is 96.43 m/s.
If they're different sizes and densities, you are able to separate the substances.
Lithium has charge of +1 and bromide has charge of - 1. So they combine to form the compound lithium bromide which is expressed as LiBr.
<h3><u>Explanation:</u></h3>
Lithium is an alkali metal placed in group 1 or periodic table. It has a valency of 1 which is achieved as lithium loses an electron to achieve a charge of +1.
Bromine is a halogen which is placed in group 17 of periodic table. It has a valency of 1 which is achieved as bromine looses an election to achieve a charge of - 1.
Lithium is the cation and bromide is the anion. So lithium is written in front and bromine following the cation. And as both of their valencies are 1, so they form the compound LiBr.
