a. it has 13 protons c. it has 13 neutrons
b. it has 13 electrons d. it has 7 neutrons
Answer:
Option-d is the correct answer.
Explanation:
As we know that C-13 has a atomic mass of 13. Also, atomic mass is given as,
Atomic Mass = # of Protons + # of Neutrons --- (1)
Since;
Atomic Mass = 13
And,
# of protons = 6 (as number of protons = atomic number)
Putting values in equation 1,
13 = 6 - # of Neutrons
Solving for Number of Neutrons,
# of Neutrons = 13 - 6
# of Neutrons = 7
Carbon-13 is a natural isotope of carbon. The isotope's mass is 13 units. The isotope consists of 7 neutrons and 6 protons.
Atomic mass of an element is defined as the summation of number of protons and number of neutrons. As given in the question, Carbon-13, the isotope of carbon has atomic mass 13.
Now, calculating the number of neutrons:
Atomic mass = No. of protons + No. of neutrons
Therefore, Carbon-13 have 6 protons and 7 neutrons.
