An atom loses or gains electrons to__________________?
Correct answer: D. all are accurate justifications
- A. Gain stability
- B. Form a bond
- C. Complete its outermost shell
- D. all are accurate justifications
Explanation
Atoms may lose or gain electrons to obtain a more stable electronic arrangement, often by completing their valence shell, and this electron transfer can produce an ionic bond. Thus all three statements describe valid purposes or consequences of electron loss or gain. The likely mistake is choosing c because the octet rule is commonly emphasized, but it is not the only valid justification.

About Periodic Properties and Trends
Periodic properties arise from electron configuration and effective nuclear charge, producing trends in atomic and ionic radius, ionization energy, electron affinity, electronegativity, metallic character and reactivity. Comparisons run across periods and down groups, with attention to common exceptions. The topic also relates these trends to the behavior of s-block and p-block elements.
