Question

Select the correct answer.
An ion has a net charge of 3+. If this ion has 8 protons, how many electrons does it have?
A. 3
B.
un
OC. 7
D.
00
E.
11

Answer 1

answer is 5 tho idk why the options so weird. anyways u have to use the periodic table, check for the element which has 8 protons. this will be oxygen.

to calculate electrons, take 16-8 hence u will have 8 electrons.

qn said u have net charge of 3+. this means that u have to minus 3 from the electrons

so 8-3 = 5

Answer 2

Answer:

5

Explanation:

An ion has a net charge of 3+

ion has 8 protons

How many electrons does it have

A neutral atom has equal number of electrons and protons.

If a neutral atom loses electron it acquires a positive charge.

So to acquire 3+ charge the atom must have lost three electrons.

So the number of protons exceeds the number of electrons by 3.
