The most important isotope of beryllium - 9Be - has 5 neutrons. The neutral atom of beryllium has 4 electrons.
4 protons, 4 electrons and 5 neutrons
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.
There are 5 neutrons, 4 protons and 6 electrons.
4 protons 4 electrons 5 neutrons
Beryllium 9 has 5 electrons.
There are 5 neutrons in beryllium 4 electrons and 4 protons.
Beryllium has 4 protons, 5 neutrons and 4 electrons.
Beryllium has 4 protons, 4 electrons and 5 neutrons (in its most stable isotope)
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.
Beryllium has an atomic number of 4, which means it has 4 protons and, in its neutral state, 4 electrons. The most common isotope of beryllium has 5 neutrons. Therefore, in a cubic cubit of beryllium, there would be 4 protons, 5 neutrons, and 4 electrons per atom, but the total number of each would depend on the number of beryllium atoms in that cubic volume.
Beryllium has 4 protons and normally 4 neutrons in its nucleus. It usually has 4 electrons orbiting that nucleus, but this number can change depending on its level of ionisation.
Beryllium has 4 particles, consisting of 4 protons and 4 neutrons in its nucleus, surrounded by 4 electrons.
