Binding Energy Flashcards
Define mass defect of an atom
Is the difference between the mass of an atom and the total mass of the particles in the atom
What is the mass defect of a nucleus?
Is the difference between the mass of the separated nucleons and the combined mass of the nucleus
Define Binding energy of a nucleus
The energy released when components join up to form an atom
The energy required to break an atom into its individual components
State the law of conservation of mass and energy
The total amount of mass and energy in the universe is constant
What is Fission
The process by which one large atoms splits up to form 2 smaller atoms with the release of energy
What is Fusion
The process by which 2 smaller atoms join together to form one larger atom with the release of energy
What is the binding energy per nucleon?
It is the binding energy of the nucleus divided by the number of nucleons.
a higher binding energy per nucleonratio implies great stability
What is the atomic mass unit or a.m.u?
It is a small unit of mass that is relevant on an atomic scale and is defined as 1/12th of the mass of a carbon-12 atom
What is mass defect of an atom ?
The difference between the mass of the atom and the total mass of particles in the atom
Einstein‘s theory and the law of conservation of mass and energy
Einstein showed from his theory of relativity that mass an energy can be converted from one Form to the other. Mass and energy are the same things in different forms. Mass can be converted to energy and therefore has an energy equivalent.
