Beryllium 9 has 5 electrons.
3: Beryllium with 5 neutrons is stable, while 4 and 6 neutrons are not, and almost never occur naturally.
5 neutrons
Beryllium should be expected to have a charge of 2+ as is expected of all the elements in Group 2 of the periodic table. But its behavior is somewhat different than other Group 2 elements because it has so few electrons. This element tends to form covalent bonds.All nuclei have a positive charge.So beryllium-9 has a positive charge.

Beryllium is a chemical element. It's used as a hardening agent in alloys. It's widely used in the aerospace industry. To find out all the details about beryllium, type in "beryllium" in your web browser and you'll get several websites describing it.
Beryllium: It passes x-rays, reflects neutrons is light, rigid and really toxic.
four protons and 5 neutrons in Be-9
The most common isotope of Beryllium is Beryllium 9, which has 5 neutrons.
Beryllium (Be-9) has 5 neutrons.
Since the mass number is protons plus neutrons, it would have 5 neutrons.
The most important isotope of beryllium - 9Be - has 5 neutrons. The neutral atom of beryllium has 4 electrons.
An element is defined as atoms with the same number of protons (and thus electrons). Beryllium has 4 protons and 4 electrons. The number of neutrons is determined by subtracting the atomic number from the atomic mass. At least three isotopes of Beryllium have been identified but there is only one stable naturally occurring isotope - Beryllium 9. If there are 4 protons, there must be 9 - 4 = 5 netrons in this isotope. The other stable isotope is beryllium 10 with a half life of 2,700,000 years and this must have 6 neutrons. This does not occur naturally but is made in atomic reactors. The other identified isotope is Beryllium - 8 which is made in the same way but immediately splits into two helium nuclei. So for most naturally occurring Beryllium, there are 5 Neutrons.
4 - protons (so it is beryllium) 5 - neutrons, therefore, it is beryllium-9 (4+5 is nine)
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.
Any element can have 4 neutrons but most of them aren't metallic. Anyway's on the periodic table it would be Be and that stands for Beryllium
Beryllium has four protons. Be9 also has five neutrons, for a total mass of 9.
The atomic number of beryllium (Be) is 4 and the atomic mass is 9 for the most stable isotope. Be-9 isotope has 5 neutrons (9 - 4 = 5).Beryllium's stable isotope (Be-9) has 5 neutrons. There are about 11 other isotopes known, Be-7 and -10 the next most common and have 3 and 6 neutrons respectively but only exist in nature in trace amounts.
Therefore beryllium has 4 protons, 4 electrons and 5 neutrons.
