Electron Distribution for Nitrogen, Arsenic, and Antimony

The electron distribution for elements can be determined by using the periodic table. Nitrogen (N) is located in Group 15, Arsenic (As) is in Group 15, and Antimony (Sb) is in Group 15 as well.

The electron distribution for these elements can be determined by following the Aufbau principle, which states that electrons fill the lowest energy levels first before moving to higher energy levels.

For Nitrogen (N), it has an atomic number of 7. Therefore, its electron distribution is as follows:

- 1s^2 2s^2 2p^3

For Arsenic (As), it has an atomic number of 33. Therefore, its electron distribution is as follows:

- 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^3

For Antimony (Sb), it has an atomic number of 51. Therefore, its electron distribution is as follows:

- 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^3

Relationship between Group Number and Atomic Structure

The group number of an element corresponds to the number of valence electrons it has. Valence electrons are the electrons in the outermost energy level of an atom.

In the case of Nitrogen, Arsenic, and Antimony, they all belong to Group 15. This means that they all have 5 valence electrons. The valence electrons are located in the outermost energy level, which is the p orbital for these elements.

The atomic structure of these elements is determined by the number of energy levels and the arrangement of electrons within those energy levels. The number of energy levels is determined by the period number of the element on the periodic table.

In summary, the group number of these elements (Group 15) corresponds to the number of valence electrons they have, which determines their chemical properties. The atomic structure of these elements is determined by the number of energy levels and the arrangement of electrons within those energy levels.
