The most common isotope of Beryllium is Beryllium 9, which has 5 neutrons.
5
Beryllium (Be-9) has 5 neutrons.
Beryllium has 5 neutrons.
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-10: protons:4 electrons:4 neutrons:6 atomic #:4 Mass #: 10
Therefore beryllium has 4 protons, 4 electrons and 5 neutrons.
Each isotope of beryllium has a different number of neutrons.
Beryllium 9 has 5 electrons.
Beryllium (Be-9) has 5 neutrons.
The most important isotope of beryllium - 9Be - has 5 neutrons. The neutral atom of beryllium has 4 electrons.
No neutrons are neutral.
Beryllium has 5 neutrons.
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.
