The aim of this experiment is to help establish the idea that the pH of oxides vary. The shielding by d electrons causes a major size decrease However, a few react with oxygen in the air to form their oxides and water when heated to high temperatures. Aluminium oxide is amphoteric, meaning it reacts with both acids and bases. ↶ 4.5 Elements in a period The periodic table is laid out in rows to illustrate recurring, (periodic) trends in the chemical behavior of the elements as their atomic number increases: a, new row is begun when chemical behavior begins to repeat, meaning that elements with a. similar behavior fall into the same vertical columns. When period 3 elements are reacted with chlorine gas the chlorides X Chlorine and argon are omitted - chlorine because it is meaningless to talk about "chlorine chloride", and argon because it doesn't form a chloride. The oxides of elements in Period 3 change from basic to amphoteric, and then to an acidic nature when across Period 3 from left to right. Physical properties. Sodium ions, with only +1 charge and a relatively large radius, hence have a low charge density and hydrolysis does not occur. Hydrides do not react with air at room temperature.
