Lithium and fluorine form LiF
Potassium and sulfur form KS2
Magnesium and chlorine form MgCl2
Sodium and calcium form Na2Ca
Strontium and oxygen form Sr2O2
Beryllium and nitrogen form Be3N2

Answer 1

it´s actually Lithium and fluorine / Magnesium and Chlorine / Beryllium and Nitrogen

Answer 2

The study of chemicals and bonds is called chemistry. There are two types of elements in the periodic table and these are metal and nonmetal.

The correct answer is options B, D, and F.

What is an element?

• An element is a pure substance consisting only of atoms that all have the same numbers of protons in their nuclei.
• Unlike chemical compounds, chemical elements cannot be broken down into simpler substances by any chemical reaction

According to the question, the metals accept electrons and nonmetals give electrons to complete their outer shell.

Hence, the correct answer is:-Lithium and fluorine, Magnesium and Chlorine, Beryllium and Nitrogen.
