Which feature of the N₂ molecule results in its high bond strength?

the presence of a triple covalent bond

the atoms are joined by metallic bonds

Why does sodium form an ionic bond with chlorine?

transfer of electrons from one atom to another

sharing of protons between atoms

formation of covalent molecules

Based on the diagram of ammonia, what is the main reason nitrogen forms bonds with hydrogen atoms?

A. To achieve a stable electron configuration

B. To lose all its valence electrons

C. To become positively charged

Which of the following best describes a covalent bond?

A. Two atoms sharing a pair of electrons

B. Transfer of electrons from one atom to another

What property of metals allows them to be hammered into thin sheets without breaking?

B. The sea of delocalized electrons allows metal atoms to move past each other.

A. Metal atoms are arranged in a fixed, unmovable pattern.

C. Metals have weak forces holding the atoms together.

D. Valence electrons are tightly bound to individual atoms.

Which of the following are typical characteristics of covalent compounds?
