Answer:
The correct option is A. Lithium Iodide
Explanation:
According to the system for naming an ionic compound, the name of the metal ion is always written first and the name of the non-metal ion is written after it.
Lithium is a metal whose ion is named as lithium ion Li+ and Iodine is a non-metal whose ion name is iodide and is written as I-. The charges on metal atoms depend on the number of group they are present on, in the periodic table. The charge on the non-metal ion would be the group number minus eight. Hence, lithium iodide is the correct answer.
D) The same number of each type of atom will always be present before and after a chemical reaction takes place.
Mass is never created or lost in a chemical reaction, so the atoms of each element must stay balanced.
