Question

A certain polyatomic ion contains 49 protons and 50 electrons. What's the net charge of this ion?A. +1B.-2C. +2D. -1

Answer 1

Net charge = -1. Option D is correct

Explanations:

Protons are positively charged ion while electrons are negatively charged electron.

Given the following parameters

`\begin{gathered} Proton\text{ number}=49protons \\ Electron\text{ number}=50electrons \end{gathered}`

Determine the net charge

`\begin{gathered} Net\text{ charge}=-50+49 \\ Net\text{ charge}=-1 \end{gathered}`

Hence the net charge of this ion is -1
