Atoms

Atoms

  • All matter, such as solid, liquid and gases, is composed of atoms.


Atoms and molecules

Atom

Atoms have three basic parts

  • Proton

  • Neutron

  • Electron

Atoms

Nucleus – is the center. There are two types of charges found in the nucleus.

  • Protons

  • Neutrons


Protons neutron

Protons & Neutron

  • Protons have a positive charge.

  • Neutrons have no charge.


Electrons

Electrons

  • Electrons have negative charge.

  • They are found circling the nucleus in paths called orbits.


Facts on atom

Facts on Atom

  • Protons have a positive charge equal in magnitude to the electron’s negative charge.

  • Neutrons have the same mass as a proton, but no charge.


Atomic number atomic mass

Atomic Number & Atomic Mass

  • Atomic Number – the number of protons in an atom.

  • Atomic Mass = Number of protons + number of neutrons.

  • Symbol – one or two letters that stand for the name of the element.
