atomic radius

Question 1

why are there large jumps in atomic radius between He and Li and again between Ne and Na?

Answer 1

because lithium and neon have less shells than helium and sodium

Question 2

why does the atomic radius of drop between lithium and Florine?

Answer 2

because the number of protons in fluorine is greater than the amount of protons on lithium ( making fluorine a greater force)

Question 3

what is strange about the radius of noble gasses in this graph?

Answer 3

the radius slightly increases because there’s more shells as you go down the row of noble gasses
