Brewer is correct but he has just described Entanglement without realising it. Viewed simply, electrons are arranged in shells around an atoms nucleus . As you know, a given orbital can hold a maximum of 2 electrons, which is why the maximum number of electrons that can be added to a given energy level n is twice the number of orbitals present on said energy level. How many electrons does each energy level hold? Each has its own specific energy level and properties. Since each orbital can hold a maximum of two electrons, the number of electrons that can share the two quantum number n=3 and ml=2 will be equal to 2 , each having opposite spin. 10 How many electrons are needed for the ground state? Electronic orbitals are regions within the atom in which electrons have the highest probability of being found. when n=2, then l= 0 and 1. In row two of the periodic table, there are two orbitals, 0=s, and 1=p. These electrons are arranged in specific energy levels surrounding the nucleus. This time, you are given both the energy level, #n=4#, and the subshell, #l=3#, on which the electrons reside. Each shell can contain only a fixed number of electrons: The first shell can hold up to two electrons, the second shell can hold up to eight (2 + 6) electrons, the third shell can hold up to 18 (2 + 6 + 10) and so on.
