    What are valence electrons?
    1. AElectrons in the outermost shell
    2. BElectrons closest to the nucleus
    3. CElectrons that are exchanged with other atoms to form bonds
    4. DElectrons that have a negative charge
    5. EElectrons that repel from positive protons
  2. 2What does the number 18.998 represent?Imagen de la pregunta 2
    1. AAverage Atomic Mass
    2. BNumber of Protons
    3. CNumber of Neutrons in an ion
    4. DAtomic Number
  3. 3An [blank_start]ion[blank_end] is when there is an atom with more or less electrons that the usual. Usually, in a stable atom, there are the same number of protons as electrons.
    [blank_start]Cation[blank_end] - more protons, less electrons >> [blank_start]positive[blank_end]
    [blank_start]Anion[blank_end] - less protons, more electrons >> [blank_start]negative[blank_end]
    1. Aion
    2. BCation
    3. CAnion
    4. Dpositive
    5. Enegative
  4. 4Ionic Bonds - [blank_start]Metal[blank_end] (loses electrons) and [blank_start]Nonmetal[blank_end] (gains electrons)
    Covalent Bonds - 2 [blank_start]nonmetal[blank_end] atoms
    Polar Covalent Bond - 2 [blank_start]different[blank_end] atoms, [blank_start]Unequal[blank_end] Sharing
    Non Polar Covalent Bond - 2 [blank_start]same[blank_end] atoms, [blank_start]Equal[blank_end] Sharing
    1. AMetal
    2. BNonmetal
    3. Cdifferent
    4. DUnequal
    5. EEqual
    6. Fnonmetal
    7. Gsame
