The determination of charge of an electron was done by R.A. Millikan in 1913,
In R.A. Millikan's working (Millikan's oil drop experiment) explained as follows
the terminal velocity of charged oil drop is measured under two conditions viz. under gravity alone and under the combined action of gravity and electric field oppose the gravity . Negatively charge drop is selected and its motion is studied.I think it's due to this electron has (-)ve charge.In fact, it is a very long experiment ,i can't explain all of it.
What else can I help you with?
Is an electron positively or negatively charged?
An electron is negatively charged.
A negatively charged subatomic particle is?
This is the electron.
Which of the following particles is negatively charged?
An electron is negatively charged.
Are electron negatively charged atoms?
No. An electron is negatively charged but it is not an atom. It is a subatomic particle and the negatively charged component of an atom.
What is a Negatively charged particle's?
Negatively charged particles in an atom are known as electrons.
Is a electron neutrally charged?
No, its negatively charged.
What is a negatively charged subatomic particle'?
electronThe electron is a negatively charged particle.
When an atom loses an electron and becomes negatively charged we refer to it as?
When an atom loses an electron and becomes negatively charged we refer to it as a positive ion
What happens to an atom's overall charge if it gains an electron?
since an electron is negatively charged, adding an electron to an atom will cause it to become negatively charged.
What's negatively charged particle?
A negatively charged partical is an electron.
What are negatively charged particles in atoms called?
.The electron is a subatomic particle that carries a negative electrical charge.(The proton carries a positive charge, and the neutron carries no charge.)In the atom the electron is negatively charged.
A negatively charged particle?
A negatively charged particle is an electron, which is a fundamental subatomic particle that orbits the nucleus of an atom. Electrons carry a negative charge equal in magnitude to the positive charge of a proton, and they play a crucial role in chemical bonding and electrical conductivity.
