Today students learned about:
Covalent Bonding- Sharing of electrons
when two atom share one pair of electrons- single bond
when two atom share two pairs of electrons- double bond
when two atom share three pair of electrons- triple bond

Class-Tuesday,January 12,2010

In today's class students learned about:
Review: Main Energy levels(K,L,M,N)
Main energy level      # of sublevels
1   K                           s
2   L                            s,p
3   M                           s,p,d
4   N                            s,p,d,f

• s,p,d and f sublevels
• writing electron configuration of 1st 10 elements of periodic table

Max numer of electrons present in the sublevels.i.e.
Sublevels         #of orbitals     Max. Number of electrons
s=2 electrons      1                                     2
p=6 electrons      3                                     6
d=10 electrons    5                                    10
f=14 electrons     7                                    14

Homework: write the summary about the atom and its structure

Class-Monday,January 011,2010

Today students worked  in pairs on the station related to the Atomic Structure Of The Atom
They applied their previous learning to find out

# of Electrons
# of Protons
# of Neutrons and atomic number 

Homework:Complete the guided reading assignment on The structure of the atom

Class-Thursday,January 07,2010

 SPS1: Discussed the structure of the atom and the locations of the subatomic particles.
           Atomic Mass and Mass Number
           Relationship of the proton Number to the electron's Identity

# of protons # of electrons (In a neutral atom)
 # of protons= atomic number
Mass Number=Protons+Neutrons
# of netrons=mass number -atomic number

Homework: Study class notes and previous tests at home.
Reminder: Class test is on Friday(01/08/10)
