Question

chemistry unit 3 common assessment
question 9/11
9 which of the following is a similarity between ionic and covalent bonds?
a both include the gaining and losing of electrons
b both include the sharing of electrons
c both make the elements more stable
d both are typically found as solids at room temperature

Explanation:

• Option A: Ionic bonds involve gaining and losing electrons (transfer), but covalent bonds involve sharing electrons. So this option is incorrect.
• Option B: Only covalent bonds involve sharing of electrons. Ionic bonds do not. So this option is incorrect.
• Option C: Both ionic and covalent bonds form to make elements more stable. Ionic bonds form to achieve a full - outer electron shell (octet rule) through electron transfer, and covalent bonds form through electron sharing to achieve a more stable electron configuration.
• Option D: Covalent compounds can be gases (e.g., \(O_2\)), liquids (e.g., \(H_2O\) at room temperature in some cases), or solids. Ionic compounds are typically solids at room temperature. So this option is incorrect.

Answer:

C. Both make the elements more stable
