atoms, elements, compounds & mixtures\ntask: rewrite the sentences if you think they are wrong\n1) all matter is made of tiny particles called elements\n2) an element is a substance made of one atom\n3) air, sea water and oxygen are mixtures\n4) compounds are easily separated as their atoms are not chemically joined together

atoms, elements, compounds & mixtures\ntask: rewrite the sentences if you think they are wrong\n1) all matter is made of tiny particles called elements\n2) an element is a substance made of one atom\n3) air, sea water and oxygen are mixtures\n4) compounds are easily separated as their atoms are not chemically joined together

Answer

Brief Explanations:

  1. All matter is made of tiny particles called atoms, not elements. Elements are made of one - type of atom.
  2. An element is a substance made of only one type of atom, not one atom.
  3. Air and sea - water are mixtures, but oxygen is an element, not a mixture.
  4. Compounds are not easily separated because their atoms are chemically joined together.

Answer:

  1. All matter is made of tiny particles called atoms.
  2. An element is a substance made of only one type of atom.
  3. Air and sea - water are mixtures, oxygen is an element.
  4. Compounds are not easily separated as their atoms are chemically joined together.
