Question

the model below shows a carbide ion. what could be done to change this carbide ion to a neutral carbon atom? remove 2 electrons add 2 electrons remove 4 electrons add 4 electrons ●=+1 〇=0 〇=-1

Explanation:

Step1: Understand ion - atom conversion

A neutral atom has equal number of protons and electrons. An ion has a charge due to a difference in the number of protons and electrons.

Step2: Analyze carbide ion

Carbide ion usually has a charge of - 4. This means it has 4 more electrons than a neutral carbon atom.

Step3: Determine the change

To change a carbide ion to a neutral carbon atom, we need to remove the extra electrons. Since it has 4 extra electrons, we should remove 4 electrons.

Answer:

remove 4 electrons
