There are 5 neutrons, 4 protons and 6 electrons.
The most important isotope of beryllium - 9Be - has 5 neutrons. The neutral atom of beryllium has 4 electrons.
Beryllium 9 has 5 electrons.
four protons and 5 neutrons in Be-9
The most common isotope of Beryllium is Beryllium 9, which has 5 neutrons.
There are 5 neutrons in beryllium 4 electrons and 4 protons.
Beryllium has 4 protons, 5 neutrons and 4 electrons.
Beryllium-10 has 4 protons and 4 electrons. Since the atomic number of beryllium is 4, this is how many protons and electrons it has. Beryllium-10 is an isotope, which means it has 6 neutrons, as the total mass number of beryllium-10 is 10.
Each isotope of beryllium has a different number of neutrons.
4 protons, 4 electrons and 5 neutrons
One beryllium atom has four (4) electrons, four (4) protons, and three (3), five (5) or six (6) neutrons, depending on the isotope being considered. The only stable isotope is Beryllium-9 (with 5 neutrons) but beryllium-10 (with 6 neutrons) has a relatively long half-life of 1.51 million years.
4 protons 4 electrons 5 neutrons
No neutrons are neutral.
