Looking at the model above, what has happened to the Lithium element to the right of the arrow?
Lithium has lost an electron; therefore a cation has been made
Lithium has lost an electron; therefore an anion has been made
Lithium has lost an electron but the element is still neutral
As Ava was writing the name of CO2 she decided that its name was monocarbon dioxide. This is incorrect. What did Ava do wrong?
Ava did nothing wrong. The correct name of CO2 is monocarbon dioxide.
Ava added the pre-fix "mono" to carbon which is never added to the 1st element's name in covalent bonding.
Ava added the pre-fix "mono" to carbon which is never added to the 1st element's name in ionic bonding.
Ava added the pre-fix "di" to oxygen which is never added to the 2nd element's name in covalent bonding.
Which is true of covalent compounds?
They share electrons
They are good conductors
They are electrically charged
They are made of a metal and nonmetal
Which is true of ionic compounds?
They are electrically neutral when dissolved in a solution
They are made by sharing electrons
They are made of metals and nonmetals
They are good conductors as solids

Two hydrogen and one oxygen atom
One oxygen atom with one oxygen atom
Two phosphorous atoms with five oxygen atoms
Which pair of atoms will form a covalent molecule?
One copper and two fluorine atoms

Covalent solutes are considered non-electrolytes. What does this mean for the conductivity of the solution?
Non-electrolytes do not dissolve in water and cannot conduct electricity
Non-electrolytes dissolve and completely dissociate in water and conduct electricity
Non-electrolytes dissolve and completely dissociate in water and do not conduct electricity
Being a non-electrolyte refers to the type of bonding and has no bearing on conductivity
What is the difference in oxidation #'s and valence electrons?
Oxidation numbers represent the # of electrons in the outermost shell and valence electrons are represented by periods.
Oxidation #s tell how many electrons are in an element and valence electrons are the ones lost or gained in a reaction
Valence electrons are the electrons in the outermost energy level and oxidation #'s tell the charge of an ion after electrons are gained or lost
They represent the same thing
Disodium sulfide
