Class-Thursday,March 03/04/10

Review: compare and contrast between chemical reactions and nuclear reactions

Today  students learned about radioactive/nuclear decay in terms of alpha decay,beta decay and gamma decay.

Homework: study your class notes at home.

Class-Wednesday,March 03/03/10

Review: Isotopes v/s radioisotopes
Today students learned about :

• Nulear Decay in which an unstable atomic nuclei convert into stable nuclei by emitting alpha,beta perticles and/or gamma radiations.
• What are alpha particles and their properties?

Homework: Study your class notes at home.

Reminder: 3rd 9 weeks exams from March 17-19

Class- Tuesday,March 03/02/10

Review: Chemical reactions and Isotopes

Today student learned about the

• difference between the chemical and nuclear reaction.
• Activity: Students made a model of the Beryllium atom having 4 protons(red pom-pom balls) and 4 neutrons(green pom-pom balls).They showed the decay of the Be-atom by losing a particle thas has 2-protons and two neutrons.So they removed 2 red and 2 green pom-pom balls from the atom.Their nuclear models was representing new element.Which is contradictory to chemical reactions.(Visual, Logical)
