Since the 2s electron has more density near the nucleus of an atom than a 2p electron, it is said to shield the 2p electron from the full effective charge of the nucleus. Therefore the 2p electron feels a lesser effect of the positively charged nucleus of the atom due to the shielding ability of the electrons closer to the nucleus than itself

Explanation of 2s-2p mixing effect on molecular orbital energy levels for homonuclear diatomic molecules/molecular ions: When mathematically mixing atomic orbitals of two atoms to form molecular orbitals for homonuclear diatomic molecules/molecular ions, one might assume that the atoms' atomic s-orbitals only mix with each other and atomic p-orbitals only mix with each other, because we assume As the 2s and 2p energies become farther apart in energy, there is less interaction between the orbitals (i.e., less mixing).

The mixing of 2s-2p orbitals is greater in which period 2 elements? what does this mean? B,C and N It means places sigma 2p at a higher energy level than pi 2p. lower energy orbitals make a greater contribution to the .. orbital and the higher energy orbitals make a greater contribution to the

Plug in the bonding electrons from the sigma 1, sigma 3 and pi orbitals and you get 8 electrons. The sigma 2 is the only anti-bonding MO that has electrons. Add these in and you get Bond order= 1/2 (8–2) which equals 6/2=3.

Mixing equal parts of the 2s, 2p x and 2p y orbitals results in three new “sp2” hybrid orbitals whose major lobes make an angle of 120˚. These new hybrid sp2 orbitals are ideal for trigonal planar geometry, i.e., atoms configured with three 2EPDs. Each sp orbital has 33% s character. The 2p y is not used in sp2

We need orbitals that have the correct directional properties and we can synthesize these from our known atomic orbitals by mixing, a process known here as hybridization .

As the 2s and 2p energies become farther apart in energy, there is less interaction between the orbitals (i.e., less mixing). A plot of orbital energies is shown below. Because of the very large energy difference between the 1s and 2s/2p orbitals, we plot them on different energy scales, with the 1s to the left and the 2s/2p to the right.

As we proceed from boron to carbon, that first 2s electron is effective in screening the second 2s electron because of its spherical orbit (2s effective nuclear charge increase=0.641). However, the first 2p electron is not as effective in screening the nucleus because of its non-spherical shape. Since the three sp 2-hybridized orbitals are created by mixing one 2s orbital and two 2p orbitals, the energy of an sp 2-hybridized orbital falls between those of a 2s orbital and a 2p orbital. The three atomic orbitals used in hybridization had a total of three electrons, which are to be distributed in the three sp 2 -hybridized orbitals equally, following the Hund’s rule.
