Question

Label the following image:

Answer 1

Answer:

I think...

A. Same atomic number

B. Isotopes of carbon

C. Different atomic mass/mass number

Answer 2

Answer :

A represent the atomic number.

B represent the element that is carbon element.

C represent the atomic mass.

Explanation :

Isotope : It is defined as the element that have the same number of protons but have the different number of neutrons of each of the atom.

Atomic number is defined as the number of protons or number of electrons.

The given element is, carbon (C)

Atomic number of carbon = 6 = number of protons = number of electrons

Mass number is defined as the sum of number of protons and number of neutrons.

Number of neutrons = Mass number - Number of protons

As we are given, $^6C_{12}$ and $^6C_{13}$

In this, the number 6 represent the atomic number of carbon, the number 12 and 13 represent the atomic mass of carbon and the symbol C represent the element is carbon.
