Charge on oil droplet = – 1.282 x 10^-18C

Charge on an electron = – 1.602 x 10^-19C

Number of electrons = q /e = (– 1.282 x 10^-18C) / (– 1.602 x 10^-19C) = 8

The number of radial land angular nodes in 4d orbital are, respectively

Payal Gupta

In 4d orbital, n = 4 and $l = 2$

Radial nodes = $n - l - 1$

Radial nodes = 4 – 2 – 1 = 1

And angular nodes, $l = 2$
