True [87]3 years ago
8 0
I think the correct answer from the choices listed above is option D. Members of the alkali metals easily lose an electron to form a +1 cation. The halogens represents element like F, Cl which easily gain an electron. Alkaline earth metals represents element like Mg, Ca which easily lose two electrons. Noble gases are Ne, Ar which are usually stable.

Answer:

The answer to your question is letter b) He and Ne

Explanation:

Elements that have similar properties are placed in the same group in the periodic table.

So

A C and F  These elements do not have similar properties because C is in group 4A and F is in group 7A. This is not the right answer.

B He and Ne  These elements have similar properties becase they are in the same group (8A).

C Al and Si  These elements do not have similar properties because Al is in group 3A and Si is in group 4A. This is not the right answer.

D N and S These elements do not have similar properties because N is in group 5A and S is in group 6A. This is not the right answer.
