50; 8; 2; 6; 10; 14

Question 2

1: n = 2, l = 0 2p: ⇒ 4 2: n = 3, l = 2 3d: ⇒ 2 3: n = 1, l = 0 2s: 4: n = 2, l = 1 4f: ⇒ 5 5: n = 4, l = 3 1s: ⇒ 3

Question 10

Did your answer include at least one of the items listed in each category below?

Revolt · Accepted Answer

Dot structures make it easy to count electrons and they show the number of electrons in each electron shell.; Arrow and line diagrams show the spin of electrons and show every orbital.; Written configurations require minimal space and show the distribution of electrons between subshells.
