Question

Lithium (Atomic #3), sodium (Atomic #11) and potassium (Atomic #19) all show similar chemical properties. Explain how this is possible.

Answer 1

Chemical properties of a compound depends upon the valence electrons of the atoms . As Lithium , sodium and potassium all have 1 valence electron and they all have tendency to lose this 1 valence electron means all are monvalent. So lithium, sodium and potassium have same chemical but different physical peopertiés.
