Rules for naming compounds

Good morning in the morning :)

Elements

• Found in the periodic table

• pure substances

• their smallest unit is the atom

• 1 type of atoms

• 
  

Metals

• Shine

• Electricity and heat conductors

• Strong

• Magnetic

• Malleable

• Ductil

• High melting points

Non-metals

• Dull

• Brittle

• Do not conduct heat or electricity

• Not magnetic

• Low melting points

• 
  

• 
  

Multiple Select

two of the following statements are false about metalic elements.

• The most of them reflect light, they are shiny

• At low temperatures they melt

• Not all of them are good conductors of heat or electricity

• There are more metals on than non-metals in the periodic table

• They can easily be broken, they are brittle

Compounds

• Combination of elements

• Pure substances

• Fixed ratio H2O (2 atoms of hydrogen bonded to 1 atom of oxygen)

• 2 or more types of atoms

• Their smallest unit is the molecule

• Chemically joined (bonds)

Multiple Select

Select the formulas that represent compounds

• O

• HCl

• Fe

• H₂O

• C₆H₁₂O₆

Rules for naming compounds of two elements

• If contains a metal, the name of it comes first

• NaCl SODIUM chloride; BeS BERYLLIUM sulfide; CaO CALCIUM oxide

• If contains a non-metal, its name is changed using "IDE" at the end

• NaCl sodium chlorIDE; LiF Lithium fluorIDE; CuO copper oxIDE

• If the compound is a combination of a metal and oxygen, its name ends with oxide

• MgO magnesium OXIDE; CaO calcium OXIDE; Al₂O₃ aluminium OXIDE

Open Ended

Select a metal and a non-metal from the periodic table.

Suggest a name for a compound made of those according the previous rules.

Write yes if you did

Write no if you did not

If not, what was your mistake?
