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.

A negatively charged particle?
A negatively charged atom is called an electron.
A negatively charged subatomic particle is?
This is the electron.
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.
Which of the following particles is negatively charged?
An electron is negatively charged.
What is a Negatively charged particle's?
Negatively charged particles in an atom are known as electrons.
What is a negatively charged subatomic particle'?
electronThe electron is a negatively charged particle.
What's negatively charged particle?
A negatively charged partical is an electron.
Is a electron neutrally charged?
No, its negatively charged.
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.
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.
Do electrons have a Negative Charge or a positive charge?
They are ALWAYS negatively charged. If positively charged it would be a positron and not an electron.
What does electron?
Electrons are negatively charged.
