Let's learn about the shapes of atomic orbitals in this video lesson. • 1. s orbitals • There is only 1 s orbital in each s subshell. • Shape of s orbital is spherical and non-directional. • Size of s orbital increases as principal quantum number n increases. • 2. p orbitals • There are 3 p orbitals in each p subshell, namely npx, npy and npz orbitals. • The orbitals are dumb-bell shaped or look like the number 8 or infinity sign. • npx lies along the x-axis, npy along the y-axis and npz along the z-axis. • Orbitals in the same subshell are degenerate or have the same energy. • Size of p orbital increases as n increases. • 3. d orbitals • Each d subshell has 5 degenerate orbitals, namely ndxy, ndyz, ndxz, ndx^2-y^2 and ndz^2 • Shape of ndxy, ndyz, ndxz and ndx^2-y^2 is cloverleaf shape with 4 loops or butterfly shaped. • Shape of ndz^2 is dumb-bell shape with a ring around its centre. • ndxy lies on the xy plane, ndxz on the xz plane and ndyz on the yz plane, but they are not along the axis. • ndx^2-y^2 lies directly along the x and y axis. • ndz^2 lies directly along the z axis. • Remember the orbitals with a square term (ndx^2-y^2 and ndz^2) will be lying directly along the axis. • Topic: Atomic Structure, Physical Chemistry, A Level Chemistry, Singapore • Please SUBSCRIBE to my channel and SHARE this video with your friends if you find it helpful! • View the full video with description at my website https://chemistryguru.com.sg/shapes-o... • This video is extracted from our Chemistry Guru on-demand video lessons. • Learn A Level Chemistry online anytime, anywhere and at your own pace!
