The halogens (group 17) gets less and less reactive as you go down the group. With Flourine being the most resctive and then the others below it becoming less reactive (not to say the others arent reactive though)
The element in group 7 period 5 is element 43, Technetium (Tc). Its chemical symbol is Tc.
The element is iodine (I). It is in group 7 of the periodic table and has 5 energy shells.
there is no element found in such a place because that spot doesn't exist. there is a period 4-7 but not 1-3 for group 6. that particular spot is open and doesn't include any elements
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.
Group 7. Fluorine, which belongs to group 7, is the most reactive 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.
Fluorine (F) is the most reactive element in group 7A (also known as group 17 or the halogens). It has a strong tendency to gain an electron to achieve a stable octet configuration, making it highly reactive.
The element in group 7 period 5 is element 43, Technetium (Tc). Its chemical symbol is Tc.
group-17 elements are called halogens. They are non-metals.They have 7 valence electrons.
Halogen oxides are acid forming, most of which are strong
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.
Element group 1 is called the alkali metals, while element group 7 is called the halogens.
The element in period 4, group 7 of the periodic table is Manganese (Mn).
