How do carbon 12 and carbon 13 differ?
select all that apply.
they have different mass numbers.
they have different amounts of neutrons.
they have different amounts of electrons.
they have different atomic charges

A) & B)

Explanation:

First, the numbers 12 and 13 represent the atomic mass number of the atoms.

The mass number is equal to the total number of protons and neutrons. Consider that any element has the same number of protons, regardless of the number of neutrons. The number of protons in Carbon is 6.

The amount of neutrons can be calculated by: mass number minus number of protons.

For Carbon 12:

For Carbon 13:

In order for the charge of the atom to be neutral, the amount of electrons must be equal to the number of protons (as they have opposite charges). And we now know that the number of protons in Carbon12 and Carbon13 are always the same

The atomic charges in both are neutral, due to the fact that they have the same amount of protons and electrons in both cases. Is only the neutrons (thus the mass numbers)that change

d is the answer i came up with

convex lenses are thicker at the middle. rays of light that pass through the lens are brought closer together (they converge). a convex lens is a converging lens. when parallel rays of light pass through a convex lens the refracted rays converge at one point called the principal focus.
