Explanation:

Step1: Identify alkali metal

Alkali metals are Group 1 elements. On the periodic table, A is in Group 1, so it matches column B 1.

Step2: Identify alkali earth metal

Alkaline earth metals are Group 2 elements. B is in Group 2, so it matches column B 2.

Step3: Identify halogen

Halogens are Group 17 elements. H is in Group 17, so it matches column B 3.

Step4: Identify transition metal

Transition metals are in the d-block (Groups 3-12). C is in the d-block, so it matches column B 4.

Step5: Identify noble gas

Noble gases are Group 18 elements. I is in Group 18, so it matches column B 5.

Step6: Identify Group 14, Period 2 element

Group 14, Period 2 is carbon's position, which is E, so it matches column B 6.

Step7: Identify 8 valence electrons (noble gas)

Noble gases have 8 valence electrons (except He). I is a noble gas, so it matches column B 7.

Step8: Identify element with 2 shells

Elements in Period 2 have 2 electron shells. E is in Period 2, so it matches column B 8.

Step9: Identify full octet valence electrons

A full octet is 8 valence electrons, which describes noble gases like I, so it matches column B 9.

Step10: Identify most electronegative element

The most electronegative element is fluorine, in Group 17, Period 2: H, so it matches column B 10.

Step11: Identify most electropositive element

The most electropositive elements are Group 1, Period 1/7. A is a Group 1 alkali metal, so it matches column B 11.

Step12: Identify element that gains 2 electrons

Elements in Group 16 gain 2 electrons to fill valence shells. F is in Group 16, so it matches column B 12.

Step13: Identify element that accepts 2 electrons

Group 16 elements accept 2 electrons. F is in Group 16, so it matches column B 13.

Step14: Identify +2 charge cation

Group 2 elements form +2 cations. B is in Group 2, so it matches column B 14.

Step15: Identify -1 charge anion

Halogens (Group 17) form -1 anions. H is in Group 17, so it matches column B 15.
