List the number of protons, neutrons, and electrons there is a pic)

The number written on bottom is called the atomic number. Atomic number is the number of protons in an atom and it is also equal to the number of electrons in an atom.

So having a look at the pic, we see a “6” written at the bottom.

So,
The number of protons are 6
The number of electrons are 6

The number written on top is called mass number and it is equal to the sum of number of protons and number of neutrons. The number written on top is 13, so mass number is 13.

So, mass number = number of protons + number of neutrons

To calculate number of neutrons using the equation I wrote we will need to subtract the number of protons from the mass number.

Number of neutrons = (mass number - number of protons)
Number of neutrons = 13 - 6 = 7.

ANSWER:

Number of protons = 6
Number of electrons = 6
Number of neutrons = 7
