which elementary particle is not present in 1H
Answers
Answer:
In particle physics, an elementary particle or fundamental particle is a subatomic particle with no (currently known) substructure, i.e. it is not ... There may be hypothetical elementary particles not described .
Explanation:
Positron is not a subatomic particle. Electrons, protons and neutrons are the subatomic particles.
An atom is the smallest particle of an element, having the same chemical properties as the bulk element. The first accurate theory explaining the nature of matter was Dalton's Atomic Theory: 1. All matter is composed of atoms, and atoms are indivisible and indestructible.
Protons and neutrons can be further broken down: they're both made up of things called “quarks.” As far as we can tell, quarks can't be broken down into smaller components, making them the smallest things we know of.
An electron is a negatively charged subatomic particle. It can be either free (not attached to any atom), or bound to the nucleus of an atom. Electrons in atoms exist in spherical shells of various radii, representing energy levels. ... The charge on a single electron is considered as the unit electrical charge.
