STD 11 - 4. Chemical bonding and molecular structure — NEET STD 11 Science — Question

$(1)$ An electron in an orbital of high angular momentum stays away from the nucleus than an electron in the orbital of lower angular momentum.

$(2)$ For a given value of the principal quantum number, the size of the orbit is inversely proportional to the azimuthal quantum number

$(3)$ According to wave mechanics, the ground state angular momentum is equal to $\frac {h}{2\pi }$

$(4)$ The plot of $\Psi \,\,Vs\,\,r$ for various azimuthal quantum numbers, shows peak shifting towards higher $r$ value

$(i)$ Ionization $(ii)$ Hydrate $(iii)$ Coordination $(iv)$ Geometrical $(v)$ Optical
