Question

can anyone help me in explaining the metal excess defect in Non stoichiometric defects extra cation ? i fail to understand it

Answer 1

If as a result of imperfection, the ratio of number of cation to anion becomes different from that indicated by the ideal chemical formula, the defects are called non – stoichiometric defects. These defects arise either due to excess of metal atoms or non metal atom or presence of impurities / foreign particle.

Answer 2

A compound may have excess metal ion if a negative ion is absent from its lattice site leaving a hole which is occupied by electron to maintain neutrality.

The holes that are occupied by electrons are called ‘F’ centres (or colour centres) and are responsible for the colour of the compound and many interesting propertie

Answer 3

But why does it have to change its formula to Zn 1+x

Answer 4

did u really get it which i posted in chat box
