In the formula, 2n2 for finding the maximum number of electrons in an orbit, n represents ____.
the orbit's or shell's serial number
According to Niel Bohr, the shells or orbits in which electrons are present in an atom are represented by K (n=1), L (n=2), M (n=3), N (n=4). The term, 'n' represents the orbit's number. For instance, n=1 represents the first orbit; n=2 represents the second orbit.
