Question

which option correctly matches the characteristics of both ionic and covalent bonds?

ionic bonds occur between metals and non-metals; atoms gain or lose electrons. covalent bonds occur between non-metals; atoms share electrons.

ionic bonds occur between non-metals; atoms share electrons. covalent bonds occur between metals and non-metals; atoms gain or lose electrons.

ionic bonds occur between metals and non-metals; atoms share electrons. covalent bonds occur between non-metals; atoms gain or lose electrons.

Explanation:

To determine the correct option, we recall the characteristics of ionic and covalent bonds:

• Ionic bonds: Form between metals (lose electrons) and non - metals (gain electrons); atoms transfer (gain/lose) electrons.
• Covalent bonds: Form between non - metals; atoms share electrons.

Now we analyze each option:

• First option: Matches the correct definitions (ionic: metal - non - metal, electron transfer; covalent: non - metal - non - metal, electron sharing).
• Second option: Swaps the bond types and their electron behaviors (ionic is misdefined as non - metal - non - metal with sharing, covalent as metal - non - metal with transfer).
• Third option: Misdefines ionic (non - metal - non - metal) and covalent (metal - non - metal) bond formations.
• Fourth option: Swaps the electron behaviors (ionic as sharing, covalent as transfer) and misaligns with bond type definitions.

Answer:

The first option (Ionic bonds occur between metals and non - metals; atoms gain or lose electrons. Covalent bonds occur between non - metals; atoms share electrons.)
