30% of 66 = 30% * 66 = 0.3 * 66 = 19.8

858, which is 66 x 13

30 electrons. Zinc-66 stands for Zinc having 66 as the Atomic Mass. We know Zinc has 30 protons and we can assume that it's in a stable state so there would be 30 electrons. This means there's 36 neutrons. (30[protons] + 36[neutrons] = 66[atomic mass]

90 because 66+24 = 90

61 is one.

66 and 605 are both multiples of 11.

The GCF of 30 and 66 is 6.

The common factors are: 1, 2, 3, 6

Like all Zinc isotopes, Zinc-66 has 30 protons and 30 electrons. It has 36 neutrons, which is why it is called zinc-66. 30+36=66.
