Respuesta :
bc the number of protons & electrons are the same but the number or neutrons are changed
Explanation:
Carbon-12 and carbon-14 are two isotopes of the element carbon. ... Atoms of carbon-12 have 6 neutrons, while atoms of carbon-14 contain 8 neutrons. A neutral atom would have the same number of protons and electrons, so a neutral atom of carbon-12 or carbon-14 would have 6 electrons.
