Beryllium has 4 protons and 4 electrons. This is because the number of protons in an atom determines its elemental identity, and an atom is electrically neutral, so it has an equal number of protons and electrons.
The isotope berrylium-8 has four each of protons, electrons, and neutrons.
Nobelium has 102 protons and 102 electrons, as the number of protons is equal to the atomic number, and in a neutral atom, the number of protons is equal to the number of electrons.
Yes, the atomic number is equal to the number of protons. The number of protons is also equal to the number of electrons
The number of electrons should = the number of protons.
protons. The number of protons in an atom is equal to the number of electrons to maintain overall neutrality.
