Chemistry Review (pg 2)
Atom
The smallest particle of an element. Nucleus
(protons and neutrons) surrounded by
electrons
Element
A collection of the same type of atom.
Examples: Oxygen (O), Silver (Ag)
Molecule
Particle formed by the chemical bonding of two
or more atoms. Examples: O2, C6H12O6
Ion
A charged particle Examples: Na+, Mg+2, Cl-, PO4
-
3, NO3
-
Isotope
Different forms of an element, each containing a
different # of neutrons and thus differing in mass.
Example:
O-16...
Ionic Bond
The attraction between a cation (+) and an
anion (-). Electrons are transferred from one
atom to another. Examp...
Covalent Bond
A strong chemical bond in which two atoms
share electrons. The sharing can be equal
(non-polar) or unequal (...
Acid/Base
Acid: Produces H+, pH < 7
Base: Produces OH-, pH > 7
Electrolyte
Substances that dissociate (break up) when
dissolved in water to form ions. Example: NaCl
Hydrogen Bond
A weak chemical attraction formed when a
slightly positive hydrogen atom in one
molecule is attracted to a s...

Chemistry review

  1. 1. Construct New Interactive Notes • Need 6 pieces of binder paper • On cover page, write – Chapter 2 and 3a: Chemistry and Cells – Name, Period, Seat # – A color picture
  2. 2. Chemistry Review (pg 2)
  3. 3. Atom The smallest particle of an element. Nucleus (protons and neutrons) surrounded by electrons
  4. 4. Element A collection of the same type of atom. Examples: Oxygen (O), Silver (Ag)
  5. 5. Molecule Particle formed by the chemical bonding of two or more atoms. Examples: O2, C6H12O6
  6. 6. Ion A charged particle Examples: Na+, Mg+2, Cl-, PO4 - 3, NO3 -
  7. 7. Isotope Different forms of an element, each containing a different # of neutrons and thus differing in mass. Example: O-16: 8p 8n O-15: 8p 7n
  8. 8. Ionic Bond The attraction between a cation (+) and an anion (-). Electrons are transferred from one atom to another. Example: Na+Cl-
  9. 9. Covalent Bond A strong chemical bond in which two atoms share electrons. The sharing can be equal (non-polar) or unequal (polar).
  10. 10. Acid/Base Acid: Produces H+, pH < 7 Base: Produces OH-, pH > 7
  11. 11. Electrolyte Substances that dissociate (break up) when dissolved in water to form ions. Example: NaCl
  12. 12. Hydrogen Bond A weak chemical attraction formed when a slightly positive hydrogen atom in one molecule is attracted to a slightly negative atom in another molecule. Not a true bond.
