**R****ecall that the quantum numbers that define an electron are:**

• **Principal Quantum Number (n)**: possible values for n are 1 to ∞

• **Angular Momentum Quantum Number (l)**: possible values for l are 0 to n – 1

• **Magnetic Quantum Number (m _{l})**: possible values for m

• **Spin Quantum Number (m _{s})**: possible values for m

For each electron in a ground-state Beryllium atom, select the set of quantum numbers that represents it. Check all that apply.

a) n = 1, l= 0, ml= –1, ms= 1/2

b) n = 2, l= 0, ml= 0, ms= –1

c) n = 1, l= 0, ml= 0, ms= 1/2

d) n = 1, l= 0, ml= 0, ms= –1/2

e) n = 2, l= 0, ml= 0, ms= 1/2

f) n = 2, l= 1, ml= 0, ms= –1/2

g) n = 2, l= 1, ml= 1, ms= 1/2

h) n = 2, l= 0, ml= 0, ms= –1/2
