Question

what type of elements are present in a metallic bond?
only non - metal elements
both metal and non - metal elements
only metallic elements

Explanation:

Metallic bonds are formed between metal atoms. In a metallic bond, the valence electrons are delocalized and move freely among the metal cations. Non - metal elements typically form covalent or ionic bonds (ionic bonds with metals), not metallic bonds. So metallic bonds consist of only metallic elements.

Answer:

only metallic elements
