Spectroscopic studies show that li can have electrons in its 1s, 2s, and 2p hartree orbitals, and that zeff(2s) 5 1.28 for the 1s22s1 con guration. estimate the energy of the 2s orbital of li. calculate the average distance of the electron from the nucleus in the 2s orbital of li.

Step-by-step explanation:

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16
