What is the name of Group 7 elements?

Explanation:
Group 7 elements are called halogens. The name Halogen comes from Greek roots meaning “salt-former,” because these elements readily form salts with metals, like sodium chloride. They are non-metals with seven electrons in their outer shell, so they gain one more electron to achieve a stable eight-electron arrangement. In reactions they typically form −1 ions (halide ions). At room temperature they mostly exist as diatomic molecules such as F2, Cl2, Br2, and I2.
