For the elements in row 2 of the PT discover the relationship between ionization and the family number of the element

Element. Family. Ionization Ener

Lithium. 1 13.6
beryllium. 2. 9.3
boron. 13. 8.3
carbon. 1 4. 11.27
nitrogen. 15 14.53
oxygen. 16. 13.62
fluorine. 17. 17.42
neon. 18. 21.56

Confused

The number of energy levels increases as you move down the group as the number of electrons increases.Each energy level is then further away from the nucleus, so atomic radiud decreases.
As you move across a period, the atomic radius decreases.
ionization energy tend to increase if you move left to right in a given period or up in the periodic table.

I understand all that, but why are the munbers all over the place? This is from the chart they gave us. I double checked the numbers and the only error is lithium. 5.39.
There is supposed to be a trend. There is no specific trend here unless it has something to do with the family number.
please help, I am lost.

your numbers certainly show that trend. Plot them on a graph if you can't see it.
