How many electrons have angular momentum quantum number ℓ=1? (Part A) n=4n=1n=3n=2 n can be 2 or 3 Tries 0/99. Show transcribed image text. Expert Answer. WebEach 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. The general formula is that the nth shell can in principle hold up to 2(n2) electrons.[1]
