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.
Be, or beryllium, has 4 protons, which is the same number as its atomic number
Non-ionized atoms of the chief isotope of beryllium have 4 electrons.
There are four electrons in a beryllium atom.
The atomic number of beryllium is 4. So it has 4 protons.
Be2+ has only 2 electrons
Be has 4 neutrons. It has 4 as atomic number.
Beryllium has 4 protons, 5 neutrons and 4 electrons.
