Orbital having shape of dumbbell with a doughnut is:

Explanation

The orbital with a shape of a dumbbell with a doughnut is called a d-orbital. d-orbitals are found in the third and higher electron shells of atoms. They have a dumbbell shape with a doughnut around the middle. The doughnut is called the nodule.The d-orbitals are named after the German word doppelt, which means "double". This is because the d-orbitals are made up of two dumbbell-shaped lobes. The lobes are oriented along the x, y, and z axes.There are five d-orbitals in total. They are called the dxy, dyz, dxz, dx2-y2, and dz2 orbitals. The dxy orbital has lobes that are oriented along the x and y axes. The dyz and dxz orbitals have lobes that are oriented along the y and z axes, respectively. The dx2-y2 orbital has a single lobe that is oriented along the x and y axes. The dz2 orbital has a single lobe that is oriented along the z axis. The d-orbitals are important for the bonding of atoms in molecules. They can also be used to explain the magnetic properties of atoms.
