What is electron proton and neutron for kids?

All atoms have the same basic parts. These are a nucleus and at least one particle called an electron. The nucleus contains protons and neutrons. Diagrams of two kinds of atoms show that each kind of atom has a different number of electrons.

What is a neutron for kid?

definition: a small particle present in the nucleus of all atoms except the hydrogen atom. Neutrons have no electrical charge. The mass of a neutron is about equal to the mass of a proton.

What is atom easy?

An atom is a particle of matter that uniquely defines achemical element. An atom consists of a central nucleus that is usually surrounded by one or more electrons. The nucleus is positively charged, and contains one or more relatively heavy particles known as protons and neutrons.

What are 4 types of atoms?

Different Kinds of Atoms

  • Description. Atoms are made of tiny particles called protons, neutrons and electrons.
  • Stable. Most atoms are stable.
  • Isotopes. Every atom is a chemical element, like hydrogen, iron or chlorine.
  • Radioactive. Some atoms have too many neutrons in the nucleus, which makes them unstable.
  • Ions.
  • Antimatter.

What is neutron give example?

The definition of a neutron is a nucleon with no charge. An example of a neutron is something that turns into a proton and electron. Neutrons are part of the nucleus of all atoms, except hydrogen, and have a mean lifetime of approximately 1.0×103 seconds as free particles.

What is the number of protons in MG?

Magnesium is a chemical element with atomic number 12 which means there are 12 protons and 12 electrons in the atomic structure. The chemical symbol for Magnesium is Mg.

What is the mass of an electron proton?

Generally, the mass of an electron is 9.1 * 10-31 Kg while that of the proton is 1.67 * 10-27 kg. The addition and removal of electrons to or from the atom are quite easy due to presence in the orbits.

What is the definition of proton in science?

A proton is a positively charged particle that resides within the atomic nucleus. The number of protons in the atomic nucleus is what determines the atomic number of an element, as outlined in the periodic table of the elements.
