Answer:
C. Copper (II) nitrate
Explanation:
It's an inorganic compound that forms a blue crystalline solid
Ions are the charged species of the atom that carries an extra or less electron. The chemical name of the compound Cu(NO₃)₂ based on polyatomic ions is copper (II) nitrate. Thus, option C is correct.
An ionic compound is a type of chemical compound that is characterized by the presence of the ions or the charged species that results in electrostatic forces leading to the ionic bond formation.
The copper (II) nitrate compound is an example of an ionic compound as the Cu atom is metal and nitrogen and oxygen atoms are the non-metals. The metallic part of the compound carries a +2 charge while the non-metallic part consists of a negative charge.
Therefore, option C. Cu(NO₃)₂ can be named chemically as copper (II) nitrate.
