M1: Chemical bonds — Skills

I can

• use the periodic table to:
  • find the symbol and atomic number for an element
  • determine the number of protons and electrons in an atom of an element
  • work out the period and group of an element
• use the chemical formula of a compound to work out how many atoms of different elements are present in it
• for any of the first 20 elements:
  • draw a bohr diagram of it
  • write its electron configuration
  • state the number of valence electrons
• use the number of valence electrons to predict how an atom will achieve a full valence shell
