Electrons are particles that are very small (1836 times smaller than a nucleon and 9.109 X 10 to the --31 times less massive than a nucleon). They have an equal amount of charge as a proton, but obviously, the electron's charge is negative. An electron is both a particle and a wave, sharing characteristics of both. Their orbits are found in cloud-like structures, and you can never exactly know where an electron is, only which structure it is found in (depending on which orbital and spin it has). Electrons can be used as valence electrons, meaning they determine the chemical properties of an element, by how that atom is able to interact with other atoms (for more see Periodic Table). Electrons can be ejected from a atom in one type of Beta decay (an antineutrino is also released, but that's a different story). The corresponding antimatter particle of an electron is the positron. Electrons are leptons (a type of fundamental particle, including 2 other similar particles and 3 corresponding antineutrinos). There is so much more to say about Electrons, consult most physics textbooks or a chemistry textbook for more!

What else can I help you with?
What are facts about electrons?
Electrons are subatomic particles with a negative charge found in atoms. They orbit the nucleus of an atom in specific energy levels or shells. Electrons are responsible for chemical bonding, electricity, and the flow of currents in electronic devices.
What 3 experimental facts about the photoelectric effect could only be explained by the idea of atoms absorbing photons of lights of a certain energy?
The existence of a threshold frequency below which no electrons were emitted. The direct proportionality between the frequency of incident light and the kinetic energy of emitted electrons. The instantaneous emission of electrons once the threshold frequency was surpassed, rather than a delayed response as would be expected in a classical wave model.
Which subatomic particle determines reactivity?
Electrons are the subatomic particles that determine the reactivity of an element. The number of electrons in the outermost shell of an atom, known as valence electrons, determines how likely an atom is to form chemical bonds with other atoms.
What are the electrons in the outer shell?
The electrons in the outermost shell of an atom are called valence electrons. These electrons are involved in forming chemical bonds with other atoms to create molecules. The number of valence electrons influences the reactivity and chemical properties of an element.
The electrons that occupy the outermost filled shell are called?
Outer energy level electrons, or valence electron.
What are some facts about electrons?

What are facts about metallic bonds?
In metallic bonding, there is a sea if delocalized electrons surrounding the positve metal ions that are held closely together. These delocalized electrons enable a metal to conduct electricity. Metals are malleable and ductile as the layers of ions are not rigidly held together and can slide past each other.
What are three facts about atoms?
They all contain electrons, protons, and neutrons. They are always neutral, or they would be Ions (I-ons) They have quarks that make up all or the protons and neutrons and electrons there are 623 billion atoms in 1g of hydrogen and 4g of helium and 7g of lithium ect 623 billion=1 mol
Is there any What are facts about helium?
Helium atom has full valence electrons in its first(or s) shell. It's very stable therefore it's inert or unreactive." It's commonly used in balloons.
What is one facts about neon?
Neon has completely filled orbitals. It has 8 valence electrons and obey octet rule (stable electronic configuration). Hence it is chemically inert (or do not react with other elements).
Facts about the element fluorine?
It is a halogen, its most common oxidation state is -1, it is a gas at room temperature (F2), It forms a weak acid (hydrofluoric acid, HF), and it has seven valence electrons.
What is another name for outermost electrons?
Electrons in the outermost shell are valence electrons!
What are the electrons in the outmost shell of an atom called?
the electrons in the outermost shell of an atom are considered to be the valence electrons.
What 3 experimental facts about the photoelectric effect could only be explained by the idea of atoms absorbing photons of lights of a certain energy?
The existence of a threshold frequency below which no electrons were emitted. The direct proportionality between the frequency of incident light and the kinetic energy of emitted electrons. The instantaneous emission of electrons once the threshold frequency was surpassed, rather than a delayed response as would be expected in a classical wave model.
The outermost electrons in an atom are called?
Valence electrons
Whuch of the following are classified as an electron group?
Lone-pair electrons, Bonded pairs of electrons
