- 13ElementContains only one type of atom e.g. Hydrogen, Oxygen, Carbon, Chlorine
Only one capital letter should be present - 14CompoundContains more than one type of element
e.g. sodium chloride, hydrogen peroxide - 15MixtureHaving more than one substance present however, they do NOT mix e.g. sand and salt
- 16dio- ... e.g. carbon DIOxide2 atoms (in this case 2 oxygen atoms combined with 1 carbon atom)
- 17Mono- ... e.g. carbon monoxide1 atom (in this case there is only 1 oxygen atom combined with the carbon atom)
- 18AtomAtoms are the building blocks of molecules. They are smaller than molecules
e.g. H2 (2 should be subscript): 2 atoms - 19Moleculeone group of element or compound bonded together
E.g. 3H2 (2 should be subscript)
3 molecules
6 atoms - 20Periodic tableA table of all the elements. There are a lot of elements (118 elements). They are all written in symbols
- 21Metalsconduct electricity
conduct heat
can be bent
shiny when polished
all are solids except for mercury
Example: cobalt, iron, gold,copper, magnesium, calcium - 22Non-Metalsdo not conduct electricity
do not conduct heat
cannot be bent (brittle)
are not shiny
can be solids, liquids and gases
Example:Hydrogen, oxygen, carbon, nitrogen, sulfur, chlorine
