Answer 1

Hi Friends !!

Here is ur Answer !!

Answer:

Electrons

Electrons are one of three main types of particles that make up atoms. Unlike protons and neutrons, which consist of smaller, simpler particles, electrons are fundamental particles that do not consist of smaller particles. They are a type of fundamental particles called leptons. All leptons have an electric charge of −1 or 0. Electrons are extremely small. The mass of an electron is only about 1/2000 the mass of a proton or neutron, so electrons contribute virtually nothing to the total mass of an atom. Electrons have an electric charge of −1, which is equal but opposite to the charge of a proton, which is +1. All atoms have the same number of electrons as protons, so the positive and negative charges "cancel out", making atoms electrically neutral.

Explanation:

Unlike protons and neutrons, which are located inside the nucleus at the center of the atom, electrons are found outside the nucleus. Because opposite electric charges attract each other, negative electrons are attracted to the positive nucleus. This force of attraction keeps electrons constantly moving through the otherwise empty space around the nucleus. The figure below is a common way to represent the structure of an atom. It shows the electron as a particle orbiting the nucleus, similar to the way that planets orbit the sun. This is however, an incorrect perspective, as quantum mechanics demonstrates that electrons are more complicated.

Answer 2

J.J Thomson along with other contributions from researchers discovered the electron.

In 1897, while experimenting with a Crookes or tube professor J.J Thomson discovered the electron.

Some of the features or characteristics of an electron are as follows:

• The negatively charged particles found in an atom are called electrons.
• The symbol for electrons is $e^{-}$
• The mass of an electron is the same as the mass of a hydrogen atom.
• Unlike neutrons and protons, the electrons are found outside the nucleus of an atom.

• The number of electrons in an atom is equal to the number of protons hence, balancing and neutralizing the atom of an element.
