An electron is a subatomic particle with a negative electric charge. It is one of the basic building blocks of matter, and is the main constituent of atoms. The electron was first discovered in 1897 by J.J. Thomson. Is an electron a particle? Yes, an electron is a particle. It is a subatomic particle with a negative electric charge. What is electron and example? An electron is a subatomic particle that has a negative electric charge. It is one of the basic building blocks of matter, and it is the primary carrier of electricity in solids. What is electron made of? Electrons are particles that have a negative charge. They are found in atoms, and they are what give atoms their structure. Electrons are held in place by the nucleus, which is made up of protons and neutrons.
What are 3 facts about electrons?
1. Electrons are negatively charged particles that orbit the nucleus of an atom.
2. Electrons are responsible for the electrical conductivity of materials.
3. Electrons can be moved from one atom to another, creating an electric current. How many electrons are in a atom? The number of electrons in an atom is determined by the number of protons in its nucleus. The number of protons in an atom's nucleus determines the element, and therefore the number of electrons in an atom of that element. The number of protons in an atom's nucleus also determines the charge of the atom.
