Compounds
This shows what elements a compound contains and the exact number of the atoms of each element in a unit of that compound.
What is a chemical formula?
This is a charged particle that has either more or fewer electrons than protons.
What is an ion?
Some nonmetal atoms are unlikely to loss or gain electrons by transferring in turn to become stable they must share electrons which is called a ________________.
What is a covalent bond?
When a chemical reaction has taken place the following three things can occur: a color change, production of a _________, and a change of ________________.
What is a solid and temperature?
A _________________ molecule is one in which the unequal sharing of electrons results in a slightly positive end and a slightly negative end.
What is polar?
These are substances in which the atoms or two or more elements are combined in a fixed proportion.
What is a compound?
This is a force of attraction between oppositely charged ions, usually a metal and a nonmetal.
What is an ionic bond?
The resulting neutral particle in a covalent bond is called this.
What is a molecule?
This is a positive or negative number that indicates how many electrons an atom has gained, lost or shared.
What is an oxidation number?
A __________________ molecule is a molecule that does not have oppositely charged ends.
What is nonpolar?
Compounds often have properties that aren’t anything like those of their individual______________.
What are elements?
In ionic compounds, the oxidation number is the same as the _____________.
What is the charge?
A single covalent bond has __________ pair of shared electrons while a double covalent bond has _________ pairs of shared electrons.
What is one and two?
This is the oxidation number for Magnesium (Mg).
What is 2+?
We can use electron dot diagrams to visualize _____________________________ and their roles in chemical bonding.
What are valence electrons?
This type of compound contains two different elements and is neutral.
What is a binary compound?
When discussing ions, metals typically have a _________________ charge while nonmetals typically have a ________________ charge.
What is positive and negative?
These are positively or negatively charged, covalently bonded group of atoms.
What are polyatomic ions?
This is the oxidation number for Iron(III).
What is 3+?
These type of compounds have a tendency to form a variety of compounds with the same two elements making naming extremely important.
What are covalent compounds?
This is the only polyatomic ion that follows the rules from ionic compound naming.
What is the ammonium ion?
The loss of electrons creating a positive charge is known as a ________________, while the gain of electrons creating a negative charge is known as an ___________________.
What is a cation and anion?
This is the overall charge for the phosphate ion.
What is 3-?
This is the overall charge for an ammonium ion.
What is 1+?
Atoms with unstable outer energy levels can ___________________________ electrons to obtain a stable outer energy level.
What is lose, gain, or share?
