Any atom with 4 protons is an atom of beryllium. If the atom is neutral, it must also have 4 electrons. However, 5 neutrons specifies an isotope, specifically Be-9, rather than an element as such.
There are particular isotopes that have similar number of electrons and neutrons. Some of these isotopes include hydrogen-2, helium-4, carbon-12 and nitrogen-14.
Lithium has 3 protons and typically 4 neutrons in its nucleus.
There is no such element: an element is neutral, so it has equal numbers of protons and electrons.Impossible:2 protons 4 neutrons and 3 electrons is the IMpossible He-1 isotope with mass number 6 (=2p+4n). Helium does not accept electrons because it is noble.Possible:2 protons 4 neutrons and 2 electrons is (elemental) Helium, isotope with mass number 6 (=2p+4n)3 protons 4 neutrons and 3 electrons is (elemental) Lithium
The atomic mass of an element is the sum of the number of protons and neutrons in the nucleus. In this case, the element has 4 protons and 5 neutrons, so its atomic mass is 4 + 5 = 9 atomic mass units (amu). The number of electrons does not affect the atomic mass.
4 protons, 4 electrons and 6 neutrons.

berylium has 4 protons. It has 4 electrons too.

The mass of the isotope 7Be is 7,01692983(11) u. The isotope 7Be has 4 protons, 3 neutrons and 4 electrons (not 6).
It could possibly be a stable isotope of Beryllium
There are too many electrons. This would be a negative ion of lithium-6 (stable but less common isotope) that does not occur naturally. The element with 3 electrons, 3 protons, and *4 neutrons* is lithium-7, the most common isotope. It forms a stable positive ion (2 electrons).
All beryllium atoms have 4 protons and 4 electrons. The number of neutrons is characteristic of a particular isotope, not of beryllium as a whole, and may be determined by subtracting 4, the number of protons, from the mass number of the isotope.
