When a group 7 element takes part in a reaction, its atoms each gain one electron.
Group 7 - physical properties. Elements in the same group of the periodic table show trends in physical properties, such as boiling point. They have the same number of electrons in their...
Physical properties of the group 7 elements Mendeleev made an early periodic table. In the modern periodic table, elements are arranged in order of atomic number in periods and groups.
The group 7 elements are highly reactive non-metals that need to gain an electron to form a 1- ion and achieve a full outer shell of electrons.

Group 7 elements are called the halogens and they're very reactive and the reactivity decreases down the group. And we know that halogen means salt maker. Properties like molecular mass, density, melting and boiling points of the elements increase down the group.
Explains the trends in atomic radius, electronegativity , first electron affinity, melting and boiling points for the Group 7 elements in the Periodic Table. Also looks at the bond strengths of the X-X and H-X bonds.
