Question

An element $Z$ has atomic number $16$. Answer the following questions on $Z$.
State the period and group to which $Z$ belongs:

Answer 1

The atomic number of $Z$ is $16$. Its electronic configuration is $2,8,6$. Now, period number tells us about the number of shells present. Here, $3$ shells are there, hence it belongs to period $3$. Group number for the element that have more than $3$ valence electrons is $10+$ the number of valence electrons. So it belongs to the group number $16$ or VI A
