Electrons are precisely distinguished by what are known as quantum numbers. i.e., n, l, ml and ms. n defines the shell. There are n subshells in the nth shell. There are (2l + 1) orbitals of each type in subshell that is, one s-orbital (l = 0), three p orbitals (l = 1), five d orbitals (l = 2) and seven f orbitals (l = 3) per subshell. ml designates the orientation of the orbital and for a given value of l, ml has (2l + 1) values. ms refers to orientation of spin of the electrons.Q. For an atom of Zn, how many electrons has n + l = 4?
प्रश्न - Zn परमाणु के लिए कितने इलेक्ट्रॉनों के लिए n + l = 4 होता है?
