Question

He mass of each Wt isotope is measured relative to C-12 and tabulated below. Use the mass of C - 12 to convert each of the masses to amu and calculate the atomic mass of Wt.

Isotope Mass
WI-296 24.6616 x Mass(¹²C)
Wt-297 24.7476 x Mass(¹²C)
Wt-298 24.8315 x Mass(¹²C)

a. What are the atomic number and mass number for the carbon isotope with seven neutrons?

Answer 1

The carbon isotope with seven neutrons has the atomic number 6, representing its protons, and a mass number of 13, which is the total count of its protons and neutrons, thus it is called Carbon-13 or 13C.

Step-by-step explanation:

The atomic number and mass number for the carbon isotope with seven neutrons can be determined by understanding that the atomic number represents the number of protons and the mass number represents the sum of the number of protons and neutrons in the nucleus.

Since all carbon atoms have an atomic number of 6, indicating six protons, and this particular isotope has seven neutrons, the mass number will be the sum of protons and neutrons, which is 13 (6 protons + 7 neutrons).

Therefore, this isotope of carbon is referred to as Carbon-13 or 13C.
