Question

Metals are structures of atoms held together by metallic bonds, which is the force of attraction between X and Y. Identify X and Y.

• A. Valence shell electrons and the metal ions

Answer 1

The correct option is A Valence shell electrons and the metal ions
In a metallic substance, all the metal atoms are bound together with the strong force of attraction between valence electrons and the metal ions. The electrons from every metal atom form a ‘sea of electrons’. They are detached electrons between many positive ions. The sea of electrons acts as a "glue" which increases the strength of the metal.
