We can say that elements in the same row have the same number of occupied energy levels.So, the correct option is (b).

The periodic table is a tabular collection of chemical elements arranged according to atomic number, starting with hydrogen and going up to oganesson, which has the highest atomic number. Elements are grouped in the periodic table in increasing order of atomic number. There are seven periods and eighteen groups in it.

The amount of energy levels or shells for the components that are present in the same row or time period will be equal. For instance, each element in the top row (the first period) contains a single electron orbital. The electrons of every element in the second row (second period) have two orbitals.

The complete question is : Now look closely at the patterns in the table. Compare the elements in each column and row. What can we say about elements in the same group and elements in the same period of the periodic table?

Select all the correct answers.

a)The number of electrons in the second energy level increases by one down each column.

b)Elements in the same row have the same number of occupied energy levels.

c)For each column, the last occupied energy level has the same number of electrons.

d)The number of electrons in the first energy level increases by one from Li to Ne.
