Answer: all atoms of the same element have the same atomic number.
Explanation:
atomic mass differentiates them, which is the same as the mass number.

Answer:
1.) Yes, Cs₂S
2.) Yes, MgF₂
3.) Yes, MgS
4.) No
Explanation:
Nonmetals are located on the right side of the periodic table in the p-block. It is safe to assume that all the other elements are metals.
Ionic bonds form between a metal and nonmetal. When determining the empirical formula, the cation (the element losing electrons) is written before the anion (the element gaining electrons). The charges can be balanced by modifying the quantity of element.
1.) Cs₂S
-----> Cesium = metal and Sulfur = nonmetal
-----> Cesium = Cs⁺
-----> Sulfur = S²⁻
2.) MgF₂
-----> Magnesium = metal and Fluorine = nonmetal
-----> Magnesium = Mg²⁺
-----> Fluorine = F⁻
3.) MgS
-----> Magnesium = metal and Sulfur = nonmetal
-----> Magnesium = Mg²⁺
-----> Sulfur = S²⁻
4.) Both cesium and strontium are metals
