Science atoms

Science atoms

1. Electrons

   • a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.

2. Protons

   • a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign.

3. Particles

   • a minute portion of matter.

4. Neutrons

   • an uncharged elementary particle that has a mass nearly equal to that of the proton and is present in all known atomic nuclei except the hydrogen nucleus.

5. Atoms

   • the basic unit of a chemical element. atoms as a source of nuclear energy.

6. Positive Charge

   • In an atom, a positive charge occurs when an atom has more protons than electrons. The proton is what determines its positive charge. ... It attracts negative charges and repels other positive charges.

7. Negative Charge

   • negative charge - having a surplus of electrons; having a lower electric potential. electric charge, charge - the quantity of unbalanced electricity in a body (either positive or negative) and construed as an excess or deficiency of electrons; "the battery needed a fresh charge"

8. Elements

   • a part or aspect of something abstract, especially one that is essential or characteristic.

9. Nucleus

   • the central and most important part of an object, movement, or group, forming the basis for its activity and growth.
