4 protons 4 electrons 5 neutrons
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.
Beryllium has 4 protons, 4 electrons and 5 neutrons (in its most stable isotope)
There are 5 neutrons, 4 protons and 6 electrons.
There are 5 neutrons in beryllium 4 electrons and 4 protons.
The element is number 4 on the periodic table- it thus has 4 protons and 4 electrons (the number of protons and electrons is always the same in an element, unless it becomes an ion). The # of neutrons will vary based on the isotope; if you are given the isotope number, subtract the number of protons (aka atomic number) from it to get the # of 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.
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's atomic number is 4. To remain neutral, it must have 4 protons and 4 electrons. Beryllium's only stable isotope is 9Be, meaning it has 9 - 4 = 5 neutrons.
Beryllium has 4 particles, consisting of 4 protons and 4 neutrons in its nucleus, surrounded by 4 electrons.
