How many orbits, orbitals and electrons are there in an atom having atomic mass $24$ and atomic number $12$ ?

Open in App

Solution

Configuration of atom= ${1 s}^{2} {2 s}^{2} 2 p^{6} {3 s}^{2}$
Three shells(orbits) are present i.e. $n = 1 (K), n = 2 (L), n = 3 (M)$
Total number of orbitals=one $1 s$ +one $2 s$ +three $2 p$ +one $3 s$ = $6$ orbitals
