For the first box you are comparing Lithium and Sodium. Second box you are comparing Nitrogen and Oxygen. Last box you are comparing Sodium and Oxygen. Your answer to the questions should be based on where these elements are located on the periodic table. For example, “Strontium has a greater atomic radius because it is in period 5 and thus has 5 energy levels (while magnesium is in period 3 and only has 3 energy levels).”

ACROSS A PERIOD: Even though there are more
electrons, there are also more protons.
This results in MORE ELECTROSTATIC ATTRACTION
which pulls all the orbitals in tighter.

EXTRA CHALLENGE!
Draw the Bohr model of
Li, Na, or K:
#1
Li
Name: Lithium
Group 1A
Period: 2
#2
Draw one of the remaining two
options from #1.
Na
Name: Sodium
Group 14
Period: 3
Draw 4 Bohr Models
#3 If you chose LI for #1, then draw N or O.
If you chose Na, then draw Por 5.
If you chose K, then draw Br.
#4
N
Name: Nitrogen
Group: 5A
Period: 2
If you chose Li for #1, then draw N or C.
If you chose Na, then draw Por S.
If you chose K, then draw Br.
Name: Oxygen
Group: 6A
Period: 2

Expert Solution

Step 1

As we go from left to right in the periodic table, the atomic radius of the atom decreases due to the addition of an extra proton, which results in a stronger pull on the electrons, while the extra electron goes to the same principal energy level.
As you move down the group, another energy level is added to the structure, leading to an increase in the atomic radius. Thus, as you move down a group, the atomic radius increases.
