L1: Why do some compounds melt at a different temperature than others?
I CAN collect data and use it to rank compounds according to relative melting point.
I CAN use similarities in compounds of known relative melting point to predict the relative melting point of substances.
L2: Why do elements combine in different ratios when forming a compound?
I CAN predict the charge of an ion based on the location of the atom on the Periodic Table.
I CAN use the ionic charge to predict the correct formula for an ionic compound.
L3: Why do electrons require different amounts of energy in order to be removed from an atom?
I CAN describe the relative amount of energy requires to remove an electron from an atom.
L4: Why do elements in the same group have common ion charges that are the same?
I CAN identify, describe and use the patterns of the Periodic Table.
L5: How do electrostatic attractions differ between ionic and covalent bonds?
I CAN describe the difference between ionic and covalent bonding.
I CAN revise my current bonding model to include new information.
L6: Why do atoms in the same period or in the same group have different sizes, ionization energies, and electronegativities?
I CAN identify, describe and use the trends of the Periodic Table.
L7: Why do some elements have different properties than others?
I CAN use experimental data to classify elements.
L8: Why does the dye mix in the water but not the oil?
I CAN cite evidence to support my rationale in explaining the results of the experiment.
L9: Why do some liquids evaporate faster than others?
I CAN collect data and use it to rank compounds according to relative rate of evaporation.
I CAN use similarities in compounds of known relative rate of evaporation to predict the relative rate of evaporation of substances.
L10 - How can we determine the identity of an ink sample?
I CAN use the results of this investigation to support the existence of intermolecular forces.
