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 = 0 = -1
Answer
Explanation:
Step1: Determine charge of carbide ion
Count electrons (-1) and protons (+1). There are 10 electrons and 6 protons, so charge is - 4.
Step2: Recall neutral atom condition
A neutral carbon atom has equal number of protons and electrons. Carbon has 6 protons, so for neutrality, it should have 6 electrons.
Step3: Calculate electron - change
Current number of electrons is 10. To get 6 electrons, we need to remove 4 electrons.
Answer:
remove 4 electrons
