What is an electron simple definition?

What is an electron simple definition?

An electron is a negatively charged subatomic particle that can be either bound to an atom or free (not bound). An electron that is bound to an atom is one of the three primary types of particles within the atom — the other two are protons and neutrons.

What is an electron simple definition for kids?

Kids Definition of electron

: An elementary particle that has a negative charge of electricity and travels around the nucleus of an atom.

What is electron with example?

Electrons are The smallest of the particles that make up an atom, and they carry a negative charge. The number of protons and electrons is equal in a neutral atom. The hydrogen atom, for example, has just one electron and one proton. The uranium atom, on the other hand, has 92 protons, and therefore, 92 electrons.

What is an electron in science terms?

(ee-LEK-tron) A small particle with a negative charge that is found in all atoms. Streams of electrons made by special equipment can be used for radiation treatment.

What is a good sentence for electron?

Electron in a Sentence

1. Inside of the atom, the electron serves as a negatively active neutron and balances the positive proton. 2. Our science teacher explained that the electron is a particle with a negative charge and is much smaller than other parts of a cell.

Where are the electrons?

Where Are Electrons? 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.

What is electron in real life?

Electrons are The subatomic particles that orbit the nucleus of an atom. They are generally negative in charge and are much smaller than the nucleus of the atom. If you wanted a proper size comparison the size of the earth in comparison to the sun would be a pretty close visualization.

Do humans have electrons?

At a pretty basic level, we’re all made of atoms, which are made of electrons, protons, and neutrons. And at an even more basic, or perhaps the most basic level, those protons and neutrons, which hold the bulk of our mass, are made of a trio of fundamental particles called quarks.

What are elements kid definition?

Science >> Chemistry for Kids. An element is A pure substance that is made from a single type of atom. Elements are the building blocks for all the rest of the matter in the world. Examples of elements include iron, oxygen, hydrogen, gold, and helium.

What is a proton kid definition?

Kids Definition of proton

: An atomic particle that occurs in the nucleus of every atom and carries a positive charge equal in size to the negative charge of an electron.
