Fluorine, F, is in group 17 (7A) and period 2.
Modern periodic table has 7 periods and 18 groups.
7 periods and 18 groups are there on the modern periodic table.
There are 18 groups in the periodic table that categorize elements based on their similar chemical properties._rows."
The horizontal rows on the Periodic Table are called periods, while the vertical columns are called groups or families. For instance, iodine is in the same group, but different period to fluorine, chlorine and bromine.
Nitrogen. There are actually two periods classified as "5", more properly "V" (Roman numeral 5). VB, towards the left side of the Table, and VA, towards the right. In Group 2, there is no Period VB, only Period VA, which is nitrogen.
The periods are the rows, and the groups are the columns, so Fluorine, F, is in Period 2 (and Group 7).
The columns are called groups and rows are called periods. There are 18 groups and 7 periods.

False; That would be called groups. Periods are horiztonal rows.
Nitrogen. There are actually two periods classified as "5", more properly "V" (Roman numeral 5). VB, towards the left side of the Table, and VA, towards the right. In Group 2, there is no Period VB, only Period VA, which is nitrogen.
