Therefore beryllium has 4 protons, 4 electrons and 5 neutrons.

Pretty much any element is identified by its atomic number or number of protons; in the case of beryllium it has four of them in its nucleus. It's somewhat a matter of convention that it is beryllium by definition so long as it has those four protons; any element might be in a different oxidation state having gained or lost electrons, or be a different isotope by varying the number of neutrons, but the atomic number or number of protons is used to identify elements.
I might be wrong but: I know that beryllium has two electrons total and the first ring can only fit two electrons so the number of valance electrons is most likely two. Please correct me if I'm wrong.
In the excited state of Beryllium the electron configuration is Be = 1s2 2s1 2p1 this is caused by one electron from 2s orbital jumping to 2p orbital to create a new orbital to allow maximum bond capacity. Maximum bond capacity is mostly used in hybridization in organic chemistry. The two new orbitals that have 1 electrons need to get a pair so each can pair with 1 electron thus making Beryllium bond with 2 electrons.
The beryllium atom has 4 electrons. As with all other elements, Beryllium atoms are most stable when they have a full outer shell of electrons. Since the neutral electron configuration of the beryllium element atom is 1s2 2s2 (total of 4 electrons) the atom either needs to pick up another six electrons, thereby becoming 1s2 2s2 2p6, or lose two electrons to become 1s2.
Beryllium has 4 protons and normally 4 neutrons in its nucleus. It usually has 4 electrons orbiting that nucleus, but this number can change depending on its level of ionisation.
The atomic number of Beryllium is four, which is also the number of protons.
Beryllium To figure this out: The atomic number of an element is the number of protons the element has in the nucleus. Using this knowledge you can figure out which element has the atomic number of four, which in this case is Beryllium.
Beryllium has four protons. 4 because that is atomic number
The number of protons determines the atomic number. Since there are for protons, the atomic number is four, and the element is beryllium, symbol Be. The atomic mass number is the number of protons plus neutrons, so in this case it is 9. There are an equal number of protons and neutrons, so there is not charge. The symbol looks like this:94Be
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.
There are four electrons in atomic 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.
The alkali earth metal with the smallest atomic radius would be beryllium(Be), number four

Beryllium.
It is Beryllium ,Be
