Keep this in • Binding energy- amount of

energy it takes to completely separate the protons and neutrons• Chain reaction- is a sequence

of reactions where by-product causes additional reactions to take place

Keep this in • Strong Nuclear Force- force

that pulls the protons and neutrons together• Electric Force (charge of

protons)- force which causes for the nucleons to be apart

GUIDE QUESTIONS

1. What is FISSION?2.How does FISSION reaction is

induced?3.What are the products of

FISSION reaction?4.What is FUSION?5.What are the requirements for

FUSION reaction to be possible?

6.What are the products of FUSION reaction?

FISSION REACTION

FISSION REACTION

• it is a decay process in which a unstable nucleus

splits into two fragments of comparable mass• it is induce by bombarding a heavy

nucleus using a neutron

HOW DOES FISSION REACTION OCCUR?

URANIUM ATOM

+

PRODUCTS of FISSION REACTION

• 2 DAUGHTER NUCLEI• EXCESS NEUTRONS

FUSION REACTION

FUSION REACTION

Two or more small light

nuclei come together to form

large nucleus

HOW DOES FUSION REACTION OCCUR?

Deuterium

Tritium

Helium

Energy

neutron

What are needed for Fusion to occur?

Extreme HEAT and PRESSURE like that

of the sun

GREAT POWER COMES FROM
