Question

Magnesium (Mg) will have chemical properties most like (2 points)

manganese (Mn).
calcium (Ca).
sodium (Na).
aluminum (Al).

Answer 1

Answer: Option (b) is the correct answer.

Step-by-step explanation:

Elements that belong to same group tend to show similar chemical properties because they contain same number of valence electrons.

For example, magnesium is a group 2 element that has atomic number 12 and its electronic distribution is 2, 8, 2.

On the other hand, calcium is also group 2 element that has atomic number 20 and its electronic distribution is 2, 8, 8, 2.

Whereas sodium is a group 1 element which has just one valence electron. And manganese is a transition element that can lose up to 7 valence electrons.

Therefore, we can conclude that both magnesium and calcium will show alike chemical properties.

Answer 2

Magnesium (Mg) will have chemical properties most like

Calcium
This is because both magnesium and calcium are in the same group of periodic table that group two. They are both alkaline earth metal hence they have same properties example they have two valence electrons.
