2. LEARNING OUTCOMES
 STRUCTURE OF ATOM
 CHANGES IN MATTER
 TYPES OF REACTION
2

3. Modern Atom

4. Quantum numbers
 THERE ARE FOUR BASIC QUANTUM NUMBERS
PRINCIPAL QUANTUM NUMER (n)
THE ORBITAL ANGULAR MOMENTUM QUANTUM
NUMBER(l=n-1)
THE MAGNETIC QUANTUM NUMBER (ml)
ELECTRON SPIN QUANTUM NUMBER(ms)
4

5. SHELL &SUB SHELLS
 n value depicts energy level
 while l=n-1
 l depicts shape and angular momentum of sub energy level
example
 K SHELL HAVING n value =1 while l=1-1=0
 Subshell will b having l=0 (spherical in shape) it will b s orbital
 ms having value –l……0……+l
 Energy levels are filled by following four rules
5

6. RULES FOR FILLING ENERGY LEVELS
 AUF BA PRINCIPLE
 PAULI EXCLUSION RULE
 HUNDES RULE
6

7. Conti…..
 n=1,l=0 orbital will be s
 L shell having n=2,l=1 orbital will have three possible states-1,0,+1
orbital will be p having three forms
 px,py,pz
 If n=3 shell is M
 l=n-1=2 orbital will b d having sausage shape
 Orbital will have -2,-1,0,+2,+1,possible energy sub level or
magnetic states
 d orbital have 5 energy sub levels

9. MODERN QUANTUM MODEL
 Proposed by SCHRODINGER
 According to which each orbital around nucleus of an atom resembles a fuzzy
cloud around the nucleus.
 The area where the probability of finding electron is more,.
 the cloud is more dense
 Where the cloud is less thick ,the probability of electron is less
 This gives the introduction of the concepts of sub energy level that are s,p,d,f

22. What is metathesis
 Are chemical reactions in which two molecules or
hydrocarbons are converted to two new hydrocarbon by the
exchange of carbon-carbon single,double or triple bonds.
 Examples
 Sodium chloride and sodium nitrate react and gives sodium
nitrate and silver chloride etc
