Electronic Structure

Question 1

Chromiums electronic structure

Answer 1

Chromium donates one electron to 3d so has 5 in 3d and one in 4s

It is more stable this way

Question 2

Copper electronic structure

Answer 2

Copper donates one electron from 4s to 3d so it has full shell

More stable

Question 3

Transition metals electronic structure trend

Answer 3

When transition metals become ions they lose 4s electrons before 3d electrons

Question 4

Electronic configuration up to 4p

Answer 4

1s, 2s, 2p, 3s, 3p, 4s, 3d, 4p

P- 6

D- 10
