Beryllium 9 has 5 electrons.
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 is a chemical element with the symbol Be and atomic number 4.
Beryllium typically has 4 neutrons in its nucleus, so an isotope with 5 neutrons would have a mass number of 9. Therefore, the atomic mass of beryllium with 5 neutrons would be approximately 9 atomic mass units (amu).
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.
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 (so it is beryllium) 5 - neutrons, therefore, it is beryllium-9 (4+5 is nine)
Beryllium has an atomic number of 4, which indicates the number of protons in its nucleus. Its atomic mass of 9 includes the total number of protons and neutrons in its nucleus. This means that beryllium has 4 protons and usually 5 neutrons.
Beryllium has four protons. Be9 also has five neutrons, for a total mass of 9.
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
The element beryllium has an atomic number of four. All atoms of this Group 2 metal, regardless of which isotope we might consider, have four protons in their nucleus. And all beryllium atoms have a +4 nuclear charge.
