Why is there not a corresponding drop in ionization energies between Bi and Po in the sixth period as N and O?

Stels [109]

Answer:

See explanation

Explanation:

According to the Journal of Chemical Education, Volume 80, No.8 (2003); "The first ionization energy of bismuth appears to be anomalous......It has been claimed that spin– orbit coupling by the Russell–Saunders scheme would lower the ground state of Bi+ ..."

However, the involvement of d and f orbitals in Bi and Po implies that the outermost orbitals are poorly screened hence the drop between nitrogen and oxygen is not observed between Bi and Po.

The same argument could be extended to explain the reason why there not a corresponding drop between Ba and Tl is the sixth period even though they are in the same group as Be and B.

In a neutral atom, the number of protons is always equal to what other part of the atom?

Licemer1 [7]

Answer:

b. The number of electrons

Explanation:

A "neutral atom" has a neutral charge. This means that its charge is equal to zero. In order for the charges to cancel out each other, the atom's positive charge should be equal to the negative charge. These being said, the number of electrons (negatively-charged) is then equal to the number of protons (positively-charged). Those atoms which are not neutral are called "ions." This means that they either have more or less electrons than the protons.
