Which element has the greatest metallic property?
Think it through first, then pick an option.
- a Na
- b Mg
- c Ca
- d K
Answer and explanation
Correct answer: d K
K is in group 1 (left) and below Na, so the most metallic.
Why the other options are wrong
- a Na: Na is above K, so less metallic. The answer is K.
- b Mg: Mg is in group 2, to the right of Na. The answer is K.
- c Ca: Ca is in group 2, right of K, so less metallic than K. The answer is K.
