1pt. An atom of carbon-14 contains six protons, eight neutrons, and six electrons. Which will an atorn of carbon-12 contain?
ladessa [460]

Answer:

B. six protons, six neutrons, and six electrons

Explanation:

Carbon-14 and Carbon-12 are the isotopes of carbon.

Isotope:

An atom of an element that contain same atomic number but different atomic mass.

The difference in atomic mass is due to the different number of neutrons present, but the number protons and electrons are remain same.

In C-14 there are six protons and six electrons while number of neutrons are,

Mass number - number of protons  = number of neutrons

14- 6 =  8

In C-12 there are six protons and six electrons while number of neutrons are,

Mass number - number of protons  = number of neutrons

12- 6 =  6

Thus in C-12, there are six protons, six neutrons and six electrons present.
