An atom of an element has five more electrons than an aluminum ion. Name the element, make up the electronic formulas of its atom in an excited and unexcited state. Indicate the valence capabilities of the atoms of this chemical element.

The Al3 + ion has 10 electrons (subtract three electrons from the serial number in the periodic table). The element you need has 5 electrons more than 10 + 5 = 15. This means phosphorus (P).

As a result of the transition from one s-electron to the d-sublevel, phosphorus can have 5 unpaired electrons. By giving them away in compounds, it can acquire the oxidation state +5 (valence 5), +3, +1. Up to an octet, it lacks 3 electrons. Taking them from other elements, phosphorus can have st.ok -3 (valency 3)
