Question

How many protons, neutrons, and electrons are in Hydrogen 2,0,1?

Answer 1

Hydrogen-2, also known as deuterium (often represented as \(^2H\) or D), is an isotope of hydrogen.

In the notation provided (Hydrogen 2,0,1):
- The "2" indicates the mass number (the total number of protons and neutrons).
- The "1" indicates the atomic number (the number of protons).
- The "0" typically refers to the number of neutrons, but generally isn't noted like this in standard notation.

For deuterium:
- Protons: 1 (since the atomic number is 1)
- Neutrons: 1 (since the mass number is 2, and the mass number = protons + neutrons)
- Electrons: 1 (in a neutral atom, the number of electrons equals the number of protons)

So, in summary, deuterium has:
- Protons: 1
- Neutrons: 1
- Electrons: 1
