Atoms, elements and compounds: definitions, isotopes and RAM

1. 1What is an atom
   [blank_start]Small particle[blank_end] that [blank_start]makes up all substances[blank_end]

   1. ASmall particle
   2. Bmakes up all substances
2. 2What is an element
   Substance that is made up of only [blank_start]1 type of atom[blank_end]

   1. A1 type of atom
3. 3What is a compound
   Formed by [blank_start]chemical reactions[blank_end]. Compounds contain [blank_start]two or more elements[blank_end]

   1. Achemical reactions
   2. Btwo or more elements
4. 4What is a mixture
   [blank_start]Impure substance[blank_end] made up of [blank_start]more than one type of atom[blank_end] but [blank_start]can be separated[blank_end]

   1. AImpure substance
   2. Bmore than one type of atom
   3. Ccan be separated
5. 5Top number is [blank_start]atomic mass[blank_end]
   Bottom number is [blank_start]proton number[blank_end]

   

   1. Aproton number
   2. Batomic mass
6. 6What is an isotope
   Form of an atom that contains the same [blank_start]summer or protons[blank_end] but a different [blank_start]number of neutrons[blank_end]

   1. ANumber of protons
   2. Bnumber of neutrons
7. 7What is the equation for RAM
   [blank_start](Isotope A relative mass × abundance A)[blank_end]+[blank_start](isotope B relative mass × abundance B)[blank_end]

   1. A(Isotope A relative mass × abundance A)
   2. B(isotope B relative mass × abundance B)
