How do you write the full electron configuration for beryllium?
Answer: The full electron configuration for beryllium is 1s2 2s2.
Explanation: The electron configuration represents the arrangement of electrons in the energy levels (shells) and subshells of an atom. Beryllium (Be), with an atomic number of 4, has four electrons. According to the Aufbau principle, electrons fill the lowest energy levels first. In beryllium’s case, the first two electrons occupy the 1s subshell, and the remaining two electrons go into the 2s subshell. Read More…
