Answer

Explanation:

Step1: Determine ion charges

Potassium (K) forms a +1 ion ($K^+$) and bromine (Br) forms a - 1 ion ($Br^-$). To form a neutral compound, the ratio of ions is 1:1.

Step2: Write the formula

The formula of the compound formed by potassium and bromine is $KBr$.

Step3: Name the compound

The name of the compound is potassium bromide.

Step4: For calcium and hydrogen

Calcium (Ca) forms a +2 ion ($Ca^{2+}$) and hydrogen (H) forms a -1 ion ($H^-$). To balance the charges, we need 2 hydrogen ions for each calcium ion.

Step5: Write the formula

The formula of the compound formed by calcium and hydrogen is $CaH_2$.

Step6: Name the compound

The name of the compound is calcium hydride.

Answer:

Part 1: formula: $KBr$ name: potassium bromide Part 2: formula: $CaH_2$ name: calcium hydride
