Chemical elements: sulfur, chlorine phosphorus – arrange in the order of increasing non-metallic properties.
To answer this question, it is enough to find out the regularity of the arrangement of chemical elements in the periodic table.
1) Along the period from left to right, metallic properties weaken, that is, from right to left – increase. Non-metallic ones increase from left to right and decrease from right to left.
2) Along the group, non-metallic properties increase from bottom to top, respectively, metallic properties – vice versa.
What are metallic properties? This is the disposition of the atom to donate electrons. You can navigate by fluorine. Fluorine is the most electronegative element (by the way, electronegativity increases / decreases similarly to non-metallic properties). We know that it gives off electrons the worst of all (because it has the smallest radius, this is also one of the properties. Me and HeMe sv-va are just determined by the radius of the atom. From right to left and from top to bottom it increases). Since it donates electrons poorly, then the elements below or to the left of it will donate electrons more easily => can be judged by the metallic properties of substances.
