Question

a covalent bond would most likely be formed between which of the following elements?
na & fe
n & f
cl & ca
zn & br

Explanation:

Covalent bonds form between nonmetals, which share electrons instead of transferring them.

• Na (sodium) and Fe (iron) are both metals, so they form metallic bonds.
• N (nitrogen) and F (fluorine) are both nonmetals, so they form a covalent bond.
• Cl (chlorine, nonmetal) and Ca (calcium, metal) form an ionic bond.
• Zn (zinc, metal) and Br (bromine, nonmetal) form an ionic bond.

Answer:

B. N & F
