four states of mind

. Thus, state of the system may be defined as its conditions of existence of the system when its macroscopic properties have definite values. When the state of a system changes its macroscopic properties also change and acquire new definite values. The macroscopic properties are..

Oxidation States - 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 tend..

Lanthanides exhibit different oxidation states like +2, +3 and +4. Among these +3 is the most stable oxidation state. The elements that attain stable electronic configuration by losing 2 or 4 electrons exhibit +2 and +4 oxidation states. ..
