U1: Atomic Structure/Properties
This is the weighted average of the isotopic masses in a typical sample of an element.
What is relative atomic mass (average atomic mass)?
This is the solid structure of an ionic compound.
What is a crystal lattice?
This is the ability of an atom to form temporary/induced dipoles.
What is polarizability?
This is the process by which solvent particles break solute particles away from one another, forming a solution.
What is dissolution?
This is the hybridization around the indicated atom in the molecule shown on the board.
What is sp3?
This is a decrease in attraction between electrons and the nucleus of an atom caused by other electrons building up repulsion.
What is electron shielding (shielding effect)?
This is the compound with the greatest bond enthalpy out of the following:
H2, O2, N2.
What is N2?
This type of substance is only conductive of electricity when molten or when dissolved in solution.
What is ionic?
This type of chromatography allows for collection of significant quantities of components of a mixture.
