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.

The element is number 4 on the Periodic Table- it thus has 4 protons and 4 electrons (the number of protons and electrons is always the same in an element, unless it becomes an ion). The # of neutrons will vary based on the isotope; if you are given the isotope number, subtract the number of protons (aka atomic number) from it to get the # of neutrons
Beryllium's atomic number is 4. Thus, it has 4 positively charged protons per atom. To remain electrically neutral then, it must also have 4 electrons per atom.
Beryllium has 4 protons and electrons and 3,5 or 6 neutrons, depending on the isotope.
Neutrons and protons are found in the cell nucleus, while electrons are found in the electron cloud surrounding the nucleus.
Atoms are composed of protons, neutrons, and electrons. Protons and neutrons are found in the nucleus of the atom, while electrons orbit the nucleus in energy levels.
In a gold atom, there are 79 protons, 79 electrons, and typically 118 neutrons in the nucleus.
Protons and neutrons are located in the nucleus of an atom. The nucleus is at the center of the atom, and protons have a positive charge while neutrons have no charge.
Protons and neutrons are found in the nucleus of an atom. Protons have a positive charge while neutrons are neutral. The nucleus is surrounded by a cloud of negatively charged electrons.
