Question

9) One difference between carbon-12 ( 2C) and

carbon-14 (CO) is that carbon-14 has
A) two more protons than carbon-12.
B) two more clectrons than carbon-12.
C) two more neutrons than carbon-12.
D) A and C only
E) B and C only

Answer 1

C

Step-by-step explanation:

this is because that Carbon 12 has 6 protons and electrons and the same goes for Carbon 14 so Choice A and choice B can't be answers so D and E arent equivalent too that means Choice C can be the appropriate answer.

further more explanation:

it's also Choice C because both carbon atoms are neutral which means that the number of protons and the number of electrons are the same so that leaves us with neutron and we get the neutron number by subtracting the mass number with the proton number so let's go on shall we!

for carbon 12= 12-6=6

for for carbon 14=14-6=8 which means the best alternative is Choice C.

Best of luck!!!
