Question 5

Name the blocks on the periodic table

Answer 5

Question 6

Full electronic configuration

Answer 6

1s2 2s2 2p6 3s2 3p6 3d10 4s2 4p6 5s2

they usually put 3d10 first and then 4p6

Question 7

Answer 7

Question 8

How do electrons spin in orbitals ?

Answer 8

They spin in opposite directions

Question 9

Energy level in sub shells

Answer 9

3d has higher energy level than 4s this is why we fill that subshell fully first and then go onto 4s

Question 10

Give the elcectronic configuration for Ca²⁺

Answer 10

Question 11

Electronic configuration for K

Answer 11
