why do elements form oxides?

The elements of group 15 combine with oxygen either directly or indirectly to form oxides. The important oxides of group 15 elements along with their oxidation states are listed in tabl..

The elements of group 15 combine with oxygen either directly or indirectly to form oxides. The important oxides of group 15 elements along with their oxidation states are listed in table. Thus, it is nitrogen, which forms all ..

The elements of group 16 form a variety of oxides. Some of these are given below: Element Oxides S SO SO 2 SO 3 S 2 O 7 Se - SeO 2 SeO 3 - Te TeO TeO 2 TeO 3 - Po PoO PoO 2 PoO 3..

Oxidation States - Halogens have only one electron less than the next noble gas. Therefore, they can get the noble gas configuration either by gaining one electron to form uninegative ion, X - , or by sharing electrons with other atoms. Thus, they show an oxidation of ..

When ammonia vapours are passed over heated cupric oxide (CuO), nitrogen is formed...

In this method potassium manganate is treated with chlorine or ozone to form potassium permanganate. ..

Amphoteric oxides are metallic oxides, which show both basic as well as acidic properties. When they react with an acid, they produce salt and water, showing basic properties. While reacting with alkalies they form salt and water showing acidic properties, e.g., ..

All the elements of this group have ns 2 np 4 configuration in their outermost shell. Therefore, the atoms of these elements try to gain or share two electrons to achieve noble gas configuration. Since oxygen has a very high value of electronegativity, it tends to achieve noble ..
