What characteristics do atoms of carbon-12 carbon-13 and carbon-14 have in common?

Answer 1

Well, the most important similarity they share is that they're both carbon. This means they have the same number of protons (six) in their nucleus. Assuming they're both electrically neutral, they will also each have six electrons. The difference is in their number of neutrons. Carbon-12 has six neutrons, carbon-14 has eight. This makes carbon-14 an isotope of carbon. Isotopes are a (usually) tiny minority of atoms of an element with a different number of neutrons than normal, maybe more, maybe less. It often means that the isotope is unstable, and may undergo one or more types of radioactive decay. In the case of carbon-14, it undergoes what is called beta decay, where one of those extra neutrons turns into a proton and an electron. The new proton makes it nitrogen, and the extra electron gets expelled from the atom's nucleus.

Answer 2

same number of electrons and protons, different number of neutrons, (two more) the molecular weight is different, but bond lengths formed with other molecules are the same (or extremely close.) However different IR spectrums are seen due to different bending/stretching.

Answer 3

Atoms of carbon-12, carbon-13, and carbon-14 all have the same number of protons (6) and electrons. The difference lies in the number of neutrons in their nuclei - carbon-12 has 6 neutrons, carbon-13 has 7 neutrons, and carbon-14 has 8 neutrons.

Answer 4

They have the same number of protons and electrons.

Answer 5

Both C-12 and C-14 isotopes of carbon have 6 protons and 6 electrons. C-12 has 6 neutrons whereas C-14 has 8 neutrons

Answer 6

they're both isotopes of the same element
