quester [9]

No, this is false!

Renewable resources can be syntesized by humans, or not: some of them can, and some can't. This is not what makes them renewable, instead it's the fact that they will still be present in the nature after usage - they will be replaced (the sun will still shine tomorrow even if we harvest its power).

Hydrogen is the simplest element it has an atomic number of 1. There are three hydrogen isotopes: H1, H2, and H3. Explain how th

Archy [21]

All isotopes of hydrogen will always contain one proton, as a change in the amount of protons will change the substance. Assuming all isotopes aren’t ions and therefore don’t have a charge, then each of these isotopes has one electron. The only difference between them is the amount of neutrons to account for the different atomic masses.

H1
one proton
one electron
zero neutrons

H2
one proton
one electron
one neutron

H3
one proton
one electron
two neutron
