A neutral atom of beryllium has 4 electrons. In a neutral atom, the numbers of electrons and protons are equal. An element's atomic number is the number of protons.
Beryllium has 4 electrons.
2 because it has two outer shell electrons out of 8 (relevant rule only for the first 20 elements)
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.
The beryllium atom has 4 electrons and the valence is 2.
A beryllium atom has 4 electrons.
Beryllium has two valence electrons.
Beryllium has 4 electrons.
Beryllium has 4 electrons.
The electrons in beryllium occupy a total of four orbitals. Beryllium has 4 electrons, which fill the 1s, 2s, and 2p orbitals.
The most important isotope of beryllium - 9Be - has 5 neutrons. The neutral atom of beryllium has 4 electrons.

Beryllium and magnesium have two electrons in their outermost energy level, as do all Group 2 elements.
Beryllium has one outer electron shell with two electrons.
There are four electrons in atomic beryllium.
Beryllium has two valence electrons.
Beryllium tends to lose two electrons to form a 2+ cation.
2 because it has two outer shell electrons out of 8 (relevant rule only for the first 20 elements)
