inter conversion of the three states

Inter-conversion of the States of Matter - Depending on the conditions of temperature and pressure, matter can exist in any of the three main states i.e., solid, liquid or gas. Matter can be inter-converted from one state to the other by the additio..

Depending on the conditions of temperature and pressure, matter can exist in any of the three main states i.e., solid, liquid or gas. Matter can be inter-converted from one state to the other by the addition or removal of heat energy. All the three states of..

A solid possesses a definite size (volume) and a definite shape under ordinary conditions; and tends to maintain these even under deforming conditions. The substances in solids are closely packed and bound by strong inter particle attraction, making them rigid and geometrical. Some commo..

BF 3 and BCl 3 are gases; BBr 3 is volatile liquid and BI 3 is a soli..

These elements have five electrons in the valence shell. The loss of five electrons is quite difficult because of energy considerations. Hence they do not form ionic compounds by loss of 5 electrons. On the other hand, these elements can also gain three electrons to complete their octets. But gain..

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 state of l..

. On further excitation, the one of the 3s electron is promoted to vacant d-orbital and this makes available 6 unpaired electrons. This accounts for oxidation state of +6. These are illustrated belo..
