How many electrons are shared between two atoms during the formation of a double covalent bond?

• A. 6 electrons
• B. 4 electrons
• C. 2 electrons
• D. 8 electrons

Answer: (B)

Verified step by step guidance

1. Understand that a covalent bond involves the sharing of electron pairs between two atoms.
2. Recall that a single covalent bond consists of one shared pair of electrons, which means 2 electrons are shared.
3. Recognize that a double covalent bond consists of two shared pairs of electrons.
4. Calculate the total number of electrons shared in a double bond by multiplying the number of pairs (2) by the number of electrons per pair (2), giving \$2 \times 2 = 4$ electrons.
5. Conclude that during the formation of a double covalent bond, 4 electrons are shared between the two atoms.
