Manganese has the symbol Mn and is not in Group 7 of the Periodic Table because it falls under Group 7 only when considering transition metals. When considering the entire periodic table, manganese is located in Group 7B.
The element in group 7 period 5 is element 43, Technetium (Tc). Its chemical symbol is Tc.
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.
The element in group 7 and period 5 is iodine, represented by the symbol I on the periodic table. It is a nonmetal that is commonly used in a variety of applications, including pharmaceuticals and dyes.
The electron configuration 1s22s22p63s23p64s23d7 corresponds to the element Manganese (Mn), which is in Group 7 (previously known as "VIIIB" or "8") and Period 4 of the periodic table.
that's manganese.
The element in period 4, group 7 of the periodic table is Manganese (Mn).

At stands for astatine which is in group 7 of the periodic table.
The electron configuration 1s22s22p63s23p64s23d7 corresponds to the element Manganese (Mn), which is in Group 7 (previously known as "VIIIB" or "8") and Period 4 of the periodic table.
that's manganese.
There are only 7 groups. There are no more.
O.S of Mn = 3+ O.S. of Cl = 7+ O.S. of O = 2-
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.
The element is iodine (I). It is in group 7 of the periodic table and has 5 energy shells.
If you mean group 7A, the element that is a liquid at room temperature is bromine.
