ZIMSEC O Level Combined Science Notes: Structure of atoms

  • Elements are made up of peculiar particles that are called atoms
  • Each element has its own unique atoms
  • The atom is the smallest part of matter that can take part in a chemical change
  • All the atoms of the same element for example iron have the same properties
  • Different atoms combine in small numbers to form compounds
  • During chemical reactions in which new atoms are formed atoms are rearranged
  • Atoms are made up of even smaller particles known as protons, neutrons and electrons
  • The atoms one element have the same number of protons and electrons

Atomic structure

  • The atom is the smallest part of an element
  • Atoms are made up of even smaller particles known as protons, neutrons and electrons
  • The atoms of one element have the same number of protons and electrons
  • an atom is made up of a nucleus containing protons and neutrons surrounded by electrons in orbits
