Arrange the elements in ascending order of their non-metallic properties: N, B, O.

Elements N, B, O are in the same period. With an increase in the nuclear charge of elements of one period, the atomic radius decreases and the number of valence electrons increases, as a result of which there is a weakening of the metallic and strengthening of the non-metallic properties of the elements. In the period, the metallic properties weaken from left to right, which means that the non-metallic properties increase. We write in ascending order of non-metallic properties: B, N, O.
Boron has the lowest non-metallic properties, oxygen has the highest.



One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
