Match the following

Answer

A-Q; B-PQRS ; C-PQR ; D-PQR

Explanation

a) Orbital angular momentum `=h/(2pi) sqrt(l(l+1))`
b) An electron in an orbital is defined by using four quantum numbers n, l , m, s.
c) Size of atomic orbital depends upon principal quantum number (n) , shape upon azimuthal quantum number (l) adn orientation upon magnetic quantum number (m).
d) Probability density of electron at the nucleus in H-like atom depends upon square wave function which depends upon three quantum numbers n , l and m
