Which type of bond forms when two or more atoms share electrons?

• A. Ionic bond
• B. Covalent bond
• C. Hydrogen bond
• D. Metallic bond

Answer: (B)

Verified step by step guidance

1. Identify the types of chemical bonds: Ionic, Covalent, Hydrogen, and Metallic.
2. Understand that a covalent bond involves the sharing of electrons between atoms.
3. Recognize that ionic bonds form when electrons are transferred from one atom to another, resulting in oppositely charged ions.
4. Note that hydrogen bonds are weak attractions between a hydrogen atom and an electronegative atom, not involving electron sharing.
5. Remember that metallic bonds involve a 'sea of electrons' shared among a lattice of metal atoms, not just between two atoms.
