Question

identify the number of atoms found in the chemical below: mg(no3)2? magnesium atom(s)? nitrogen atom(s)? oxygen atom(s)

Explanation:

Step1: Analyze magnesium atoms

The subscript of \(Mg\) in \(Mg(NO_3)_2\) is \(1\), so there is \(1\) magnesium atom.

Step2: Analyze nitrogen atoms

In the \(NO_3\) group, the subscript of \(N\) is \(1\), and there are \(2\) \(NO_3\) groups (because of the subscript \(2\) outside the parentheses). So the number of nitrogen atoms is \(1\times2 = 2\).

Step3: Analyze oxygen atoms

In one \(NO_3\) group, the subscript of \(O\) is \(3\), and there are \(2\) \(NO_3\) groups. So the number of oxygen atoms is \(3\times2=6\).

Answer:

• Oxygen atoms: \(6\)
• Nitrogen atoms: \(2\)
• Magnesium atoms: \(1\)
