Question

Compare the Atomic Radius of Lithium (Li) and
Potassium (K) and EXPLAIN.

Answer 1

Lithium has a smaller atomic radius than potassium

Step-by-step explanation:

Lithium has fewer electrons therefore fewer orbitals (1s2, 2s1) vs Potassium with more electron and therefore orbitals (1s2, 2s2, 2p6, 3s2, 3p6, 4s1)
