Question

how many electrons would be found in the ion whose symbol is given below?
n^{3-}

Explanation:

Step1: Find the atomic number of nitrogen

The atomic number of nitrogen (\(N\)) is \(7\). This means a neutral nitrogen atom has \(7\) electrons.

Step2: Consider the charge of the ion

The ion is \(N^{3 -}\). A negative charge indicates the ion has gained electrons. The charge of \(3-\) means it has gained \(3\) electrons.

Step3: Calculate the number of electrons in the ion

We use the formula: \( \text{Number of electrons in ion}=\text{Number of electrons in neutral atom}+\vert\text{Charge}\vert\). Substituting the values, we get \(7 + 3=10\).

Answer:

\(10\)
