It has traces of gaseous sodium in its atmosphere, which is very tenuous.
Helium: He, 2 protons. Oxygen: O, 8 protons. Iron: Fe, 26 protons. Gold: Au, 79 protons.
The number of protons in Beryllium is 4.
The number of protons in an atom's nucleus determines its chemical identity.
Beryllium has 4 protons
it is not unique because no one can find it
There are no features
hi i am askin that how i Mexico is unique
It has traces of gaseous sodium in its atmosphere, which is very tenuous.
The likely word is "unique" (special, rare, one-of-a-kind).
It is the only state in the lower 48 that can only be accessed via another Country (Canada).
The Autobahn is comparable to a highway or freeway. It connects the cities all over Germany. It is unique since there are parts without speed limit.
There is no unque answer. It could be any one of (17, 71), (28, 82) and (39, 93)
Non for it is imposable to have protons in a proton.
In most cases, if you give me only a serial number, and no info on make, model, caliber, then no. A serial number is not unque, or it would be 20 numbers long.
Helium: He, 2 protons. Oxygen: O, 8 protons. Iron: Fe, 26 protons. Gold: Au, 79 protons.
Protons are protons, no matter what element they are in.
