Concept explainers
(a)
Interpretation:
The chemical formula of a compound that contains hydrogen and potassium should be written. Whether the compound is ionic or covalent should be mentioned.
Concept introduction:
The location of each element in the periodic table determines the formula of the hydride it forms. Alkali metals form ionic hydrides and have the formula
(b)
Interpretation:
The chemical formula of a compound that contains hydrogen and sulfur should be written. Whether the compound is ionic or covalent should be mentioned.
Concept introduction:
The location of each element in the periodic table determines the formula of the hydride it forms. Alkali metals form ionic hydrides and have the formula
