<u>Answer:</u> The correct answer is Option A.

<u>Explanation:</u>

There are 3 subatomic particles present in an atom. They are: protons, electrons and neutrons.

Protons carry positive charge, electrons carry negative charge and neutrons does not carry any charge.

Any neutral atom has an equal number of protons and electrons.  An ion is formed when atom looses or gain electron.

  • If an atom gains electrons, it will have more number of electrons than protons. Thus, it will carry negative charge and form an anion.
  • If an atom looses electrons, it will have less number of electrons than protons. Thus, it will carry positive charge and forms a cation.

Thus, an ionized atom will always have unequal number of protons and electrons.

Hence, the correct answer is Option A.

Butoxors [25]

Answer:

One of the main uses of the cathode ray tube is in the Cathode  ray oscilloscope

Explanation:

Cathode rays are produced when a gas in an evacuated glass at very low pressure and high pressure breaks up into positive and negative ions. the negative ions move towards the anode(positive electrode) while the positive ions move towards the cathode(negative electrode), and there they knock off electrons (which are known as cathode rays) from the metal plate of the cathode.

Cathode ray tubes are mainly used in oscilloscopes, television picture tubes and in computer screens.

The cathode ray oscilloscope is used in a.c. and d.c. voltage measurements, observation of waveforms, time measurements, etc.
