1pt. An atom of carbon-14 contains six protons, eight neutrons, and six electrons. Which will an atorn of carbon-12 contain? O A. seven protons, five neutrons, and six electrons
OB. six protons, six neutrons, and six electrons
OC. five protons, seven neutrons, and five electrons
OD. 12 protons, no neutrons, and 12 electrons

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.

OB. six protons, six neutrons, and six electrons

Explanation:

Atoms of carbon - 14:                      Carbon -12

              Protons  = 6                                6

              Neutrons  = 8                             6

              Electrons  = 6                               6

An atom of carbon-12 will have an equal number of protons and electrons but different number of neutrons. The two give species are isotopes.

Therefore, the two isotopes will differ in the number of neutrons they have.

in scientific notation, the value of the  speed of light in a vacuum

  will be written as 2.995 * 10^8. when this value is represented in the form of

  a * 10^b, then, a = 2.995 and b = 8.

the value of the speed of light in a vacuum given above can also be rounded up to approximately 300000000. in this case, the scientific notation will be written as 3 *10^8.
