Question

Define metallic character.

• A. An atom is said to be a metal if it loses one or more electrons when supplied with energy
• B. An atom is said to be an metal if it loses only one electron when supplied with energy
• C. An atom is said to be a metal if it gains one or more electrons when supplied with energy
• D. An atom is said to be a metal if it gains only one electron when supplied with energy

Answer 1

The correct option is A An atom is said to be a metal if it loses one or more electrons when supplied with energy

Metallic character refers to the level of reactivity of a metal. Metals tend to lose electrons in chemical reactions, as indicated by their low ionization energies. So, an atom is said to be a metal if it loses one or more electrons when supplied with energy
