Nathan Ramsey is the youngest member of the dance group Diversity.
Rhenium has 7 isotopes. The most stable and abundant isotopes are rhenium-185 and rhenium-187.
Helium 3 and helium 4 are naturally occurring isotopes 5 thru 10 are exotic isotopes.
Hydrogen-1 isotopes have one proton and no neutrons. Hydrogen-2 isotopes have one proton and one neutron.
1. Sodium has 20 isotopes and 2 isomers. 2. Only the isotope 23Na is stable. 3. The stable isotope 23Na and the radioactive isotopes 22Na and 24Na (these isotopes exist in traces) are natural isotopes.
No
Beryllium is a member of group 2, an Alkaline Earth Metal.
well actually you can't delete the group but you can: if you wanna just let the last member be in charge 1. go to the group 2. then click leave group 3. it will notify you that the last member will be in charge if you want the group just to be deleted 1. delete all the members 2. then go to edit 3. then click leave group 4. it will notify you that since you were the only member left the group will be deleted
copper has 2 stable isotopes

Rhenium has 7 isotopes. The most stable and abundant isotopes are rhenium-185 and rhenium-187.
There are three naturally occurring isotopes of hydrogen. The most common isotope, hydrogen-1, has no neutrons. It accounts for 99.99% of all hydrogen. Hydrogen-2 has a single neutron and accounts for most of the remaining .01%. Hydrogen-3 with two neutrons only exists in trace amounts.
Helium 3 and helium 4 are naturally occurring isotopes 5 thru 10 are exotic isotopes.
Hydrogen-1 isotopes have one proton and no neutrons. Hydrogen-2 isotopes have one proton and one neutron.
