The Nature of Bonds
What is an ionic bond?
This type of bond is a complete transfer of valence electrons.
What is MgF2?
The ionic formula for the compound formed between Mg^+2 and F^-1.
What is malleability?
The physical property that allows metals to be hammered into shapes.
What is insoluble?
The term for an ionic compound that does not readily form a solution in water.
What is electrostatic attraction?
The type of attraction that forms the metallic bond.
What is a polyatomic ion?
A stable group of atoms with an overall charge, such as NO3^-.
What is Lead (II) nitrite?
The name for the compound Pb(NO2)2.
What is brittleness?
This is the reason ionic crystals are brittle: like charges repel when the lattice is distorted.
What is Iron (III) hydroxide (FeOH3)?
The name and formula of the insoluble precipitate formed from FeCl3 and NaOH.
What are delocalized electrons?
The core term for electrons that are not tied to one atom and move throughout the lattice.
What is a cation?
An atom that acts as an electron donor will form this positively charged ion.
What is Iron (III) sulfate?
The name for the compound Fe2(SO4)3, which requires Roman numerals.
What is electrical conductivity?
This property is conducted well by metals due to the mobility of delocalized electrons.
What is dissociate?
When a soluble ionic solid dissolves in water, it completely undergoes this process to form aqueous ions.
What is the boiling point?
The strength of a metallic bond is best indicated by this temperature point.
What is the octet rule?
The rule that atoms try to satisfy by losing or gaining electrons to achieve a full valence shell.
What are parentheses?
When writing a formula like Ca(OH)2, these are used to show more than one polyatomic ion is present.
What is the solid state?
A key difference: Ionic compounds conduct electricity only when molten or dissolved, while metallic solids conduct electricity in this state.
What are sparingly soluble (or slightly soluble)?
The term for compounds that dissolve only to a small extent.
What is an alloy?
A substance made by melting two or more elements together, like brass, that improves properties.
What is a monatomic ion?
The specific name for an ion that has a charge of 3+ or higher, like the aluminum ion.
What is Al2O3?
The ionic formula for aluminum oxide, Al^+3 and O^-2.
What is ductility?
The term for a metal being able to be drawn into wires.
What is decanting?
The separation technique used to remove a solid precipitate from its solution by pouring off the liquid.
What is density?
The metal property explained by the closely packed atoms fitting "as many as possible into the available volume."
