How many electrons have been removed from a positively charged electroscope?

In summary, the conversation is about solving a problem involving the number of electrons removed from a positively charged electroscope with a net charge of 7.5x10^-11 C. The solution involves dividing the net charge by the charge of a single electron, which is 1.6x10^-19 C. The result is the number of electrons that have been removed.

Hello everyone! I'm having a problem with this question from my book...

How many electrons have been removed from a positively charged electroscope if it has a net charge o 7.5x10^-11 C?

Can someone explain to me how to solve this problem>?
Thank you very much!

Hello,

What is the charge of a single electron? What about two? What about an arbitrary number call it "x" electrons?

What's the charge on each electron?
 
  • #4


it's 1.6x10^-19 C

so does it mean that 7.5x10^-11/ 1.6x10^-19 is the number of electrons?

yes!
 

FAQ: How many electrons have been removed from a positively charged electroscope?

What is the definition of an electron?

An electron is a subatomic particle that carries a negative charge and orbits around the nucleus of an atom.

What are the properties of an electron?

Electrons have a mass of approximately 9.11 x 10^-31 kilograms and a charge of -1.602 x 10^-19 coulombs. They also have a quantum property called spin, which can be either "up" or "down".

How are electrons arranged in an atom?

Electrons are arranged in energy levels or shells around the nucleus of an atom. The closest shell to the nucleus can hold a maximum of 2 electrons, while the second and third shells can hold up to 8 electrons each.

What is the role of electrons in electricity?

Electrons are responsible for carrying electric charge and creating electrical currents. When electrons move from one atom to another, they create a flow of electricity.

How do electrons behave in different situations?

Electrons can behave like particles or waves, depending on the experiment being conducted. They also exhibit behaviors such as interference and diffraction, similar to light waves.
