Question
An element having atomic number $120$ have not yet been discovered. What will be its its position in long form fo periodic table ?
✓
Answer
b
$120 = [U_{40}]\, 8s^2$
Therefore it can be placed in 8th period and $2^{nd}$ group.
$120 = [U_{40}]\, 8s^2$
Therefore it can be placed in 8th period and $2^{nd}$ group.
