Naming / Formulas
This is the beginning of the name of every ionic compound, with the sole exceptions being those that have positive polyatomic ions.
What is a metal / the metal atom?
A compound has more than one ________.
What is "element?"
OR what is "type of atom?"
These are the pages of the Chemistry Reference Tables where you can find an element's electronegativity.
What are pages 10 & 11? (Table S)
True or False: A chemical reaction requires a chemical change, aka. a new substance being made.
What is True?
True or False: Something that goes from solid form to aqueous form has undergone a chemical change.
What is False?
[That is a physical change.]
True or False: You don't use prefixes when naming covalent compounds.
What is False?
This type of bonding involves a sharing of electrons, in order for each atom to reach stability.
What is covalent bonding?
Other than lowercase deltas with positive/negative symbols, this is the way to draw a depiction of a dipole.
What is a cross-base arrow?
This type of reaction has oxygen gas as a reactant.
What is combustion?
This is the name of a positive ion.
What is a cation?
This is the molecular formula for iron (II) oxide.
What is FeO?
This type of bonding happens when there is a non-temporary electron transfer.
What is ionic bonding?
This is the accepted range for the electronegativity difference of a polar bond.
What is 0.4-1.8?
[If you're within 0.1 on either side, you still get the point.]
This is the opposite of synthesis (aka. combination).
What is decomposition?
This is the name of a class of ion that is made of multiple atoms, bonded covalently, that operates like a single unit in an ionic bond.
What is a polyatomic ion?
OR what are polyatomic ions?
This is the name of N2O4
What is dinitrogen tetroxide?
OR what is dinitrogen tetraoxide?
True or False: All atoms are trying to reach the stable octet.
What is False?
(Ex: duet rule with the first four elements, B with the sextet rule, P can hold more than 8 electrons, etc.)
If the EN difference in a bond is classified as less than 0.4 (usually, it's a value of 0), then this is what the bond can be classified as.
What is a nonpolar bond?
OR what is a nonpolar covalent bond?
This type of reaction requires an element & (separate from that element) a compound on the left side of the arrow, as well as a full reactionary exchange between the lone element and one of the elements in the compound.
What is single replacement?
This is the formula for carbon diselenide.
What is CSe2?
True or False: This correct name for Mg(OH)₂ is magnesium (II) hydroxide.
What is False?
This type of bonding adopts the electron sea model, in which all the metal atoms in a metallic solid contribute their valence electrons to form a “sea” of mobile electrons.
What is metallic bonding?
[No, this will not be on the test, but it could be on the Regents. This is literally all you need to know about metallic bonding for the Regents.]
If the electronegativity difference in a bond is over 1.8, this is what the bond can be classified as.
What is ionic?
This is a major example of double replacement, often used to help clean and purify things.
What is neutralization?
If all identical bonds on a central atom of a molecule appear to have dipoles that cancel each other out, and there are no lone pairs on the central atom, this is the designation given to that molecule.
What is nonpolar?
