Explanation:
Detailed explanation-1: -4 protons, 5 neutrons, and 4 electrons are there in an atom of beryllium.
Detailed explanation-2: -The fourth shell holds 32 electrons; 2 in a 4s orbital; 6 in three 4p orbitals; 10 in five 4d orbitals; and 14 in seven 4f orbitals. The exact arrangement of electrons in an atom’s shells and subshells is the atom’s electron configuration.
Detailed explanation-3: -The element with atomic number 4 is beryllium, which means each atom of beryllium has 4 protons. A stable atom would have 4 neutrons and 4 electrons.
