| Question | Answer |
| What is an atom? | Smallest possible unit of an element that retains the physical and chemical properties of its element. |
| what is an element? | A substance that cannot be broken down into simpler substances by chemical reactions. |
| Ion | Charged atom or molecule. |
| isotope | Atoms of an element that have the same atomic number but different mass number. |
| compound | molecules made from more than one type of atom. |
| molecule | made of atoms that have combined chemically. |
| What is the difference between atoms and elements? give an example of each. | Both share the same chemical properties. An element cant be broken down further. And an atom is a smallest form of an element that still regains its physical and chemical properties. |
| What is the difference between molecules and compounds? | Molecules are made of atoms that have combined chemically. But compounds are molecules that have more than one atom. |
| How is an ion formed? | An ion is formed by a charged atom or molecule |
| What is a polar covalent bond? how is it made? give an example. | Covalent bond formed by an unequal sharing of electrons between atoms. Ex:molecular hydrogen (H2) |
| What is a non-polar covalent bond? how is it made? give an example. | Covalent bond formed by an equal sharing of electrons between atoms. Ex:molecular hydrogen (H2) |
| What is a ionic bond? how is it made? give an example. | Bond formed by the electrostatic attraction after the complete transfer of an electron from a donor atom to an acceptor. Ex: NaCl(salt :D) |
