1. BIOCHEMISTRY BS NURSING 13 th Febrauary (Monday) 1

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

3. Modern Atom 3

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 m s 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 7

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 9

12. EXAMPLES EXAMPLES OF PHYSICAL CHANGE Crushing a can Melting an ice cube Boiling water Mixing sand and water Breaking a glass Dissolving sugar and water Chopping wood etc 12

13. EXAMPLES OF CHEMICAL CHANGE Digestion of food Burning of paper and log of wood Boiling an egg Electroplating a metal Milk going sour Photosynthesis Respiration etc 13

17. 17

18. 18

19. Single displacement 19

20. 20

21. Double displacement (Metathesis) 21

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 22
