BEAUTY IS A SOURCE OF ABIDING JOY
ANYTHING THAT IS NATURAL AND INNOCENT BEAUTY LIES IN IT
BEAUTY LIES IN THE INNOCENT FACE OF WOMAN
BEAUTY LIES IN THE SMILE OF A CHILD
BEAUTY LIES IN ANYTHING THAT COMES FROM HEART
BEAUTY IS NOT ONLY PHYSICAL BEAUTY
THE PURITY OF SOUL IS BEAUTY
BEAUTY IS TO SEE , BEAUTY IS TO FEEL
BEAUTY IS NOT TO TOUCH
THAT IS WHAT BEAUTY IS ALL ABOUT

INORGANIC MADE EASY

  1. Remember first and the last element of the group
  2. When first & any element of group is compared then exceptional properties are due to anamolous behaviour
  3. When last & any element of group is compared then exceptional properties are due to inert pair effect
  4. Any compound if fumes in air it is due to formation of HCl
  5. Any question related to angle of bond see the position of bonded electrons on the central atom and size of atom if all electrons-bonded & lone pairs are concentrated on atom & size is small so repulsions & angle increases if not angle is less
  6. Any compound has different bond length it is due to different types of bonds
  7. Any compound is passive towards a reagent only if it forms oxide layer
  8. If last element shows exceptioal properties it is due to presence of poor shielding orbitals
  9. A compound is more covalent if it has more oxidation state
  10. Proticity means number of OH bonds
  11. For predicting oxidant or reductant property of any elememt in compound check:
  • group of element
  • max. & min. oxidation state it can show
  • what oxidation state it is showing in given compound & answer
  • if max. it will be oxidant :if min. it will be reductant: if intermediate it will be both

PROJECTS OF STUDENTS

ACTION

ACTIONS SPEAK LOUDER THAN WORDS
HALF-HEARTED ACTION IS INCOMPLETE WORK LEADING TO UNSATISFACTORY RESULT AND WASTAGE OF TIME.
IF YOU WOULD HAVE A THING WELL DONE DO IT YOURSELF
BRAVE ACTIONS NEVER WANT A TRUMPET
THE WORLD IS PURIFIED NOT BY ACTION, BUT NOBLENESS OF LIFE
THE ONLY MAN WHO NEVER MADE A MISTAKE WAS A MAN WHO NEVER DID ANYTHING
