Question

Another carbon isotope has six protons and seven neutrons in its nucleus. What do you think this carbon isotope is called?

Answer 1

Answer: C-13 isotope

Step-by-step explanation:

Mass number is defined as the sum of number of protons and neutrons that are present in an atom.

Mass number = Number of protons + Number of neutrons

Atomic number is defined as the number of protons or number of electrons that are present in an atom.

Atomic number = Number of electrons = Number of protons

For carbon : number of protons = 6

number of neutrons = 7

Thus Atomic number = 6

Mass number = 7+ 6= 13

Thus isotope is called as carbon-13 isotope.

Answer 2

Carbon - 13

Step-by-step explanation:

For most of the elements other than that of hydrogen, the isotopes are named for the mass number.

Example : Carbon atoms with 6 neutrons have mass number of 12 ( as
`6\ protons +6\ neutrons=12` ), so they are known as carbon-12.

Given that:

Protons = 6

Neutrons = 7

Mass = 6 + 7 = 13

So the name is Carbon - 13 . The symbol is
`^(13)_(6)C`
