7th 7s + 7p + 7d + 7f 2+6+10+14=32

Answer 1

Look at goodnotes drawing

Question 2

All s hold ? electrons in 1 orbitals

Answer 2

2e

Question 3

All p hold ? electrons in 3 orbitals

Answer 3

6e

Question 4

All d hold ? electrons in 5 orbitals

Answer 4

10e

Question 5

All f hold ? electrons in 7 orbitals

Answer 5

14e

Question 6

Electron Configuration

Fe

Answer 6

First use periodic table to find electrons
Fe has atomic number of 26 so 26e

Using the chart fill in the sub shells until all electrons are used

1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d⁶

Question 7

Electron Configuration

P

Answer 7

First use periodic table to find electrons P has atomic number of 15 so 15e

Using the chart fill in the sub shells until all electrons are used

1s² 2s² 2p⁶ 3s² 3p³
