The element is Technetium with the symbol, Tc.
Tc The element is Technetium
The element with the symbol At is Astatine. Astatine is a Group 17(7) Halogen and is radioactive. It has 85 electrons in 6 shells, with 7 electrons in the outer shell.
O.S of Mn = 3+ O.S. of Cl = 7+ O.S. of O = 2-
There are only 7 groups. There are no more.

Mn, Manganese

The element with the symbol At is Astatine. Astatine is a Group 17(7) Halogen and is radioactive. It has 85 electrons in 6 shells, with 7 electrons in the outer shell.
At stands for astatine which is in group 7 of the periodic table.
The 107th element on the Periodic Table of Elements is Bohrium. Bohrium Symbol: Bh Atomic Number: 107 Group: 7
O.S of Mn = 3+ O.S. of Cl = 7+ O.S. of O = 2-
There are only 7 groups. There are no more.
a group 7 element
Group one elements are the most reactive with group 7 elements as it is the easiest way for the elements to complete their outer shell as the group one element gives its extra electron to the group 7 element and then the group 7 element has a full shell too.
If you mean group 7A, the element that is a liquid at room temperature is bromine.
that's manganese.
