Naming / Formulas
This comes first in the name of every ionic compound, with the sole exceptions being those that have positive polyatomic ions.
What is a metal / What is the cation?
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?
True or False: Nonpolar molecules can exhibit hydrogen bonding.
What is a FALSE? In order to have a hydrogen "bond", the molecule MUST be polar, have a dipole, and also contain Hydrogen!
This type of reaction has only one reactant and two or more products.
What is synthesis?
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 an electron transfer.
What is ionic bonding?
This is the accepted range for the electronegativity difference of a polar bond.
What is 0.4-1.7?
[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 Na2SO4
What is Sodium Sulfate?
True or False: Most atoms are trying to reach the stable octet of electrons.
What is TRUE?
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 exchange between the lone element and one of the elements in the compound.
What is single replacement?
This is the formula for Magnesium Phosphide.
What is Mg3P2?
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?
If the electronegativity difference in a bond is over 1.8, this is what the bond can be classified as.
What is ionic?
This type of reaction results when two compounds react and all the cations are switched with new anions.
What is double replacement?
If all identical bonds on a central atom of a molecule appear to have electronegativity differences that cancel each other out, resulting in a symmetrical charge distribution, this is the designation given to that molecule.
What is nonpolar?
