NAMING ELEMENTS

1
NAMING ELEMENTS

• The chemical symbol and the name of the elements
  must be known before starting any discussion in
  chemistry. There is a correlation between the
  name and the chemical symbol.
• The chemical symbol is usually the first or the
  first and second letter of the name.
• H stands for the hydrogen atom
• He is helium Li is lithium
• Or it could be the first and third letter
• Mg is magnesium Mn is manganese
• Or it could be the letters for the Old (Latin,
  Greek, etc.) name
• Fe is iron (ferrum latin) Cu is copper
  (cuprum)

NAMING ELEMENTS

• There are 7 homonuclear diatomic elements.
• These elements do not exist alone readily
  under the conditions experienced on the surface
  of the Earth.
• H - hydrogen atom H2 - hydrogen
• N - nitrogen atom N2 - nitrogen
• O - oxygen atom O2 - oxygen
• F - fluorine atom F2 - fluorine
• Cl - chlorine atom Cl2 - chlorine
• Br - bromine atom Br2 - bromine
• I - iodine atom I2 - iodine
• You must be extra careful ( specific) when
  naming these elements
