As we go farther from the nucleus, the energy of orbitals increase. Also, the farther an electron is from the nucleus, the more repulsion it has to face because of other electrons(more screening effect) and hence it is easier to remove that electron.so n=1 which is very close to the nucleus has least energy and n=7 which is far away from nucleus has higher orbital energies.

Convert 32.56 km/hr into ft/hr
Gekata [30.6K]
Note that
1 m = 3.2808 ft

Therefore
1 km = 3280.8 ft
and
32.56 \,  \frac{km}{h} = (32.56 \,  \frac{km}{h})*(3280.8 \,  \frac{ft}{km}) =  1.0682 \, \times 10^{5} \, \frac{ft}{h}

Answer: 1.0682 x 10⁵ ft/hr

Judging by the electron domain geometry, which type of hybrid orbitals does this molecule have? s sp sp2 sp3
Aleksandr-060686 [28]
The molecule have TETRAHEDRAL HYBRID ORBITAL.
SP3 hybridization involves the mixing of one orbital of S sub level and three orbitals of P sub level of the valence shell. All the orbitals possess equivalent energies and shapes. The SP3 orbital has 25% S character and 75% P character. S and P refers to the s and p sub shells.<span />
