Group 7 atoms, also known as the halogens, have a full outer electron shell and are one electron short of having a full shell. Due to their high electronegativity and small atomic radius, they strongly attract electrons in order to achieve a stable electron configuration, making it harder for them to gain an additional electron.

What do atoms of group 17 elments give off when they gain electrons?

Atoms of group 17 elements (halogens) give off energy in the form of light when they gain electrons. This process is known as electron capture, which releases energy as the electron moves to a lower energy level.


When non metals and metal react which atoms gain electrons?

Halogens, group 17 on the periodic table, typically gain or share one electron in covalent bonds


What is a very reactive group of mostly nonmetals whose atoms gain or share one electron in a chemical reaction?

Halogens


The elements Li and F combine to form an ionic compound The electron configurations in this compound are the same as the electron configurations of atoms in which group?

The electron configurations of LiF will be the same as the electron configurations of atoms in Group 18 (noble gases) because Li will lose its single electron to attain a stable octet similar to the noble gases, while F will gain an electron to achieve a complete valence shell.


How does the reactivity of halogens change as you go down group 7?

As you go down group 7 (halogens), reactivity decreases. This is because as you move down the group, the outer electron shells of the halogens are further away from the nucleus, making it harder for them to gain an electron and react with other elements. Additionally, the atomic size increases which leads to weaker intermolecular forces between the atoms.

Do atoms of the halogen family of elements typically gain two electrons when they react?

Yes, halogen atoms typically gain one electron to achieve a stable electron configuration. This results in a full outer electron shell, similar to the noble gases.
