Question

protons: 9
neutrons: 10
electrons: 10
ion
neutral

Explanation:

Step1: Determine charge

In a neutral atom, number of protons = number of electrons. Here, protons = 9, electrons = 10.
Charge = \( ( + 1)\times\text{Number of protons}+(- 1)\times\text{Number of electrons}\)
\(=9\times( + 1)+10\times(-1)\)
\(=9 - 10=-1\)

Answer:

Ion
