Boron Valence Electrons

Can you estimate the approximate valence electrons of boron and oxygen?

B +3 and +6

To calculate the efficient atomic charge, subtract: (atomic number) (atomic electron)

There are other ways to calculate the specific value of an effective core load, but there is no need to pay attention to that problem.

For Boron:

Order number: 5

Nuclear electrons: 2

But finding electrons in the nucleus? Electronic configuration: 1s2 2s2 2p1

Bourne has 2 basic electrons and 3 valence electrons.

(Atomic number) (atomic electron)> (5) (2) = +3

For oxygen:

Atomic number: 8

Nuclear electrons: 2

But finding electrons in the nucleus? Electronic configuration: 1s2 2s2 2p4

Bourne has 2 basic electrons and 6 valence electrons.

(Atomic number) (atomic electron)> (8) (2) = +6

+3 and +6

B is correct because the atom number of boron is 5 and the electrons are reduced by 2 = nucleus i.e. 52 = 3.

Boron and oxygen

The valence electrons of an oxygen atom are attracted to a positive charge about twice as much as boron, where oxygen electrons are placed close to the nucleus, giving it a small radius.

B is fine.

Does anyone care to tell me why it is B?

The electron shield causes an efficient atomic charge, ZEEF, which is why boron is more than oxygen. Assume that the valence of boron or oxygen is close to that of the electron.

There are other ways to calculate the effective cost of an effective center load, but this issue does not need to be addressed.

B is correct because the atom number of boron is 5 and electrons = 2 are subtracted from the nucleus, i.e. 52 = 3.
The valence electrons of the oxygen atom attract about twice as much positive charge as the boron, where the oxygen electrons are placed close to the nucleus, giving it a small radius.
