the study of discharge of electricity through gases leads to the discovery 1)structure of atom
2) nucleus
3)spectral lines
4) electron
Answers
Answer:
1) Structure of Atoms......
Explanation:
The study of electric discharge through gases gives valuable information regarding the structure of atoms. This has led to the discovery of electrons by J. J. Thomson and later on, to the discovery of X-rays by Roentgen. A discharge tube is an arrangement to study the conduction of electricity through gases.
The study of the discharge of electricity through gases leads to the discovery of 4) electrons.
4) Electron:
J. J. Thomson discovered electrons. A discharge tube is a device used to investigate the conduction of electricity through gases. The study of electrical discharge through gases led to the discovery of electrons.
Explanation for incorrect answer:
1)structure of an atom:
The structure of an atom is made up of its nucleus and the arrangement of electrons around it. The primary structure of an atom is made up of protons, electrons, and neutrons. So it is the incorrect answer.
2) nucleus:
On the left, the electrical force is pushing protons apart, while on the right, the strong force is acting on both protons and neutrons inside a nucleus. So it is the incorrect answer.
3)spectral lines:
A spectral line is a dark or bright line in an otherwise uniform and continuous spectrum that results from light emission or absorption in a narrow frequency range when compared to nearby frequencies. So it is the incorrect answer.
As a result, the study of electrical discharge through gases leads to the discovery of electrons.
