6 to the power of 12C
How many protons are in this isotope

 If you look on the periodic table, you'll see that carbon has an atomic number of 6 6 66. This tells us that carbon- 12 12 1212, like any isotope of carbon, has six protons in its nucleus. Using unified atomic mass units makes the masses of these particles much easier to understand and compare.

"hydrogen bonding is the attraction of h atoms in the water molecule (slight + charge) to o atoms in a neighboring water molecule (slight - charge); it is a weak interatomic force. but it is still strong enough to the water molecules "stick" together."
