What element is in group 17 and period 2 of the periodic table?

The periodic table is a tabular classification and arrangement of chemical elements in order of increasing atomic number into groups and periods.

The groups are vertical columns that span from group 1 - group 18The period is horizontal rows that span from period 1 - 7.

Chemical elements in the same groups tend to share the same properties.

The group 1 elements are called alkali metals. They are highly reactive metals. They form an electrovalent bond with group 17 elements (halogens).

The group 2 elements are alkaline earth metals. They are the most abundant metals on earth.

The group 3 - 12 elements are Transition Metals.Group 17 is the halogen family.Group 18 is the Noble gas.

On the periodic table, the element in group 17 is a member of the halogen family.

Since it is in period 2, which is the second row on the periodic table;

Then, the name of the element is Fluorine.

Therefore, we can conclude that the atomic element that is in group 17 and period 2 on the periodic table is Fluorine.
