Answer:
It is a fundamental concept that atomic spectra are discontinuous the electron's energy levels are quantized which is a quantum mechanics concept that a system is limited to certain energy states which depends on the particular system being refereed to
Explanation:
Atomic electrons posses only specific energy levels with nothing in between those levels, it can be excited to a higher energy level by gaining the required energy or lose energy in quantized packets to drop to a lower energy level hence the discontinuous spectral lines
Answer:
a. Help accomplish a job
Explanation:
Energy is defined as the ability to do work. It is the ability to get a job done.
Where energy is deficient, no job or work can be done.
- In a water behind a dam, potential energy is stored.
- Potential energy is due to the position of a body.
- A moving car has kinetic energy which the energy due the motion of a body.
- Electrical energy is used to carry the currents in a circuit round about.
