Energy in the Atom (2)

Question 1

Potential Energy

Answer 1

Energy stored in the system. Could be released.

- In Atoms PE is stored in the mass of the particles and the binding system that hold the structure together.

Question 2

Kinetic Energy

Answer 2

Generated by motion.

- In Atoms the movement of Electrons generates Kinetic Energy.

Question 3

Law of Conservation of Matter

Answer 3

Matter can neither be created nor destroyed; only change in form

Energy can neither be created nor destroyed; only change form

Question 4

Electron Volts (eV)

Answer 4

• Measure for Radiation

- The amount of energy gained by the charge of one Electron moved across the potential difference of one volt.

Question 5

Energy Prefixes

Answer 5

• Kiloelectro-Volts (KeV = 1000 V)

- Megaelectron-Volts (Mev = 1,000,000 eV)
