Using the periodic table and your knowledge of atomic structure. compare the number of electrons in a carbon-12 and carbon-14 isotope. a) both have 6 electrons. b) carbon-12 has 6 electrons and carbon-14 has 8 electrons. c) carbon-12 has no electrons and carbon-14 has 2 electrons. d) carbon-12 has 12 electrons and carbon-14 has 14 electrons.

a.both have 6 electrons

Explanation:

Every Carbon atoms has 6 electrons. So, both have 6 electrons.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
