Question

an isotope of carbon has 6 protons and 8 neutrons. how is this isotope written symbolically? a. c2 b. c6 c. c8 d. c14

Answer 1

Its C-14  as the mass number (C-Χ) is the sum of the protons and the neutrons 

hope that helps 

Answer 2

Answer: The correct answer is Option d.

Explanation:

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

Atomic number = number of protons = number of electrons

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

Atomic mass = Number of protons + Number of neutrons

General representation of an isotope is $_Z^A\textrm{Z}$

where,

A = atomic mass

Z = atomic number

X = symbol of an atom

We are given:

Number of protons = atomic number = 6

Number of neutrons = 8

Atomic mass = 6 + 8 = 14

The atomic symbol is $_{6}^{14}\textrm{C}$

Hence, the correct answer is Option d.
