Answer 1

Answer:

Your answer is....

Explanation:

b. Mg² & Al

Answer 2

Explanation:

Mg : 12 protons pulling 12 electrons

Mg2+ : 12 protons pulling 10 electrons.

so, size of mg2+ is smaller than Mg

Al : 13 protons pulling 13 electrons.

Al3+ : 13 protons pulling 10 electrons.

so, size of Al3+ is smaller than Al.

we also know that atomic size decreases along a period from left to right. Al and Mg both belong to 3rd period and Mg comes first from left.

So, Mg is greater in size than Al.

Now think in Al3+ and Mg2+:

Al3+ is smaller in size than Mg2+ as 13 protons pulling will be greater than 12 protons pulling same number of electrons that is 10.

So let arrange the sizes:

Mg > Al > Mg2+ > Al3+

So,

Largest species: Mg

Smallest species: Al3+

correct option is (c)
