TEST ONE STUDY GUIDE ATOM - smallest unit of an element and retains all of the elements properties! Molecule compound! Valence electrons - the number of bonds the atom needs to fill its outermost shell! Example- oxygen has an atomic number of 8. It has 2 electrons in the first shell, and 6 in the second shell (the valence shell) it needs TWO BONDS to get to 8 electrons, a full shell. Carbon has an atomic number of 6. It needs to form FOUR BONDS to fill its outershell up to 8. Electronegativity - how badly an atom needs electrons. Greatest to Least- Oxygen, Nitrogen, Carbon, Hydrogen and Sodium. The periodic table: electronegativity increases from left to right! covalent bond - H-H. they each share one electron! Monosaccharides or simple sugars are classified by their carbonyl group. (Aldehyde or Ketone) Molecular weight- 1 mol = the exact molecular weight. .5 mole = ½ the molecular weight. All of these can change the shape of a protein:
