Solution
The correct option is E 7
In the modern periodic table, there are 18 columns called groups and 7 rows called periods.
The seventh period is still incomplete in the sense that there are more elements being discovered which will find a place in this row. While their structure can be predicted, most properties cannot be confirmed until tangible proof of existence is witnessed.
