How many electron proton and neutron are there in berullium?

Beryllium (watch the spelling) is element number 4. That means that a beryllium atom has 4 protons; if the atom is neutral it has 4 electrons (however, it might not be neutral, in this case it can have more or less), and the number of neutrons varies, depending on the isotope - between 1 and 13 neutrons in the case of beryllium.
