2n²

Question 3

What are ORBITALS?

Answer 3

A region where UP TO TWO ELECTRONS of OPPOSITE SPINS are found.

Question 4

What are the 4 types of orbitals and how many electrons can each hold?

Answer 4

’s’ orbitals can hold 2 s electrons in each shell.
‘p’ orbitals can hold 6 p electrons in each shell.
‘d’ orbitals can hold 10 d electrons in each shell.
‘f’ orbitals can hold 14 f electrons in each shell.
