An atom of carbon-12 and an atom of carbon-14 differ in(1) atomic number(2) mass number(3) nuclear charge(4) number of electrons

Sagot :

atmosfears
(2) mass number
the number after the two carbons is the mass number, the two carbons are different isotopes of each other
isotopes have the same number of protons but different number of neutrons, neutrons and protons make up the atomic mass number, so if you add neutrons to the atom the mass number increases
i hope that makes sense!

Answer:

The correct answer is option (2).

Explanation:

Carbon-12:

Atomic Number = 6

Mass number = 12

Nuclear charge =  number of protons = +6

Number of electrons = 6

Carbon-14:

Atomic Number = 6

Mass number = 14

Nuclear charge =  number of protons = +6

Number of electrons = 6

An atom of carbon-12 and an atom of carbon-14 only differ in their mass number as C-12 has mass number of 12 and C-14 has mass number of 14.
