Periodic table group
Group 7
Group 7 is a vertical column of the periodic table containing Manganese, Technetium, Rhenium, Bohrium. Elements in the same group have the same number of valence electrons, which is why they show related chemical behavior. A d-block transition metal group headed by manganese. Technetium, directly below manganese, was the first element produced artificially.

Frequently asked questions
What elements are in group 7?
Group 7 contains 4 elements: Manganese, Technetium, Rhenium, Bohrium.
What properties do group 7 elements share?
Elements in group 7 have the same number of valence electrons, so they react in related ways. Atomic radius increases down the group as electron shells are added, and first ionization energy generally decreases down the group. A d-block transition metal group headed by manganese. Technetium, directly below manganese, was the first element produced artificially.
