Question

1. how are molecules formed?

Explanation:

Molecules are formed when atoms bond together. This can occur through different types of chemical bonds such as covalent bonds (where atoms share electrons), ionic bonds (where electrons are transferred between atoms creating ions that attract each other), or metallic bonds (in metals where electrons are delocalized among a lattice of metal atoms).

Answer:

Molecules are formed when atoms bond together through covalent, ionic, or metallic bonds.
