What conclusions can be drawn about the existence of carbon-12, carbon-13, and carbon-14?
question 5 options:
these are forms of carbon and they accommodate 6 neutrons and 6 electrons but each contains a difference number of protons - 6, 7, and 8 respectively.
these are isotopes of carbon and they all contain 6 protons and 6 electrons but each contains a difference number of neutrons - 6, 7, and 8 respectively.
these are configurations of carbon and they have 6 protons and 6 neutrons but each contains a difference number of electrons - 8, 7, and 6 respectively.
these are ions of carbon and they consist of 6 protons and 6 electrons but each contains a difference number of neutrons - 8, 7, and 6 respectively.

These are isotopes of carbon and they all contain 6 protons and 6 electrons but each contains a difference number of neutrons - 6, 7, and 8 respectively.

Explanation: Isotopes of an element have similar number of protons but different number of neutrons.

General representation of an element is given as: where,

Z represents Atomic number  (for neutral atom) = number of protons= no of electrons

A represents Mass number  = number of protons + number of neutrons

X represents the symbol of an element

Thus   ,   and   all contain same number of protons i.e 6 but contain (12-6) =6, (13-6)=7 and (14-6)=8 neutrons respectively.

the earths atmosphere is made up of nitrogen and oxygen. solids can turn into gasses through a process called sublimation. sublimation is the transition of a substance directly from the solid to the gas phase, without passing through the intermediate liquid phase.
