Question

How many protons, neutrons, and electrons are in Amethyst?

Answer 1

`30` protons, `30` neutrons, and `30` electrons in `1` molecule.

Explanation:

Pure amethyst is a variety of quartz, also known as silicon dioxide, which has the formula `SiO_2`.
So, the number of protons, neutrons, and electrons in `1` molecule of amethyst would be the sum of the protons, neutrons, and electrons for `1` atom of silicon and `2` atoms of oxygen.

`1` atom of silicon has `14` protons, `14` neutrons (in its most abundant isotope, `"silicon-14"`), and `14` electrons.

`1` atom of oxygen has `8` protons, `8` neutrons (in its most stable isotope, `"oxygen-16"`), and `8` electrons.

So, `1` molecule of `SiO_2` would have `14+2xx8=30` protons, `14+2xx8=30` neutrons, and `14+2xx8=30` electrons.
