Question

A certain polyatomic ion contains 49 protons and 50 electrons. What's the net charge of this ion?Question 15 options:A) +1B) +2C) –1D) –2

Answer 1

INFORMATION:

We know that:

- A certain polyatomic ion contains 49 protons and 50 electrons

And we must find its net charge

STEP BY STEP EXPLANATION:

Atoms have the same number of protons and electrons, hence atoms are neutral.

Proton is positively charged and electron is negatively charged.

Since one electron is extra in the polyatomic ion, the ion must have negative charge extra.

Therefore,

total net charge of the ion

= +49 -50

= -1

So, the correct option would be C)

ANSWER:

C) –1
