Why do elements form bonds?
To have full valence shells/to be stable
A positively charged ion is called a/an _____.
cation
Rank the types of bonds possible in covalent bonding from shortest to longest.
triple, double, single
Does CO2 contain ionic or covalent bonds?
covalent
Which group does not tend to form bonds?
Noble gases
This bond is when two or more atoms share electrons.
covalent bond

A negatively charged ion is called a/an _____.
anion
True or False: All elements want to have eight valence electrons.
False. (ex: hydrogen and helium need only 2, sulfur and phosphorous can hold 10)
Does HF contain covalent or ionic bonds?
covalent
What determines which type of bond forms between atoms?
Difference in electronegativity
element class
The bond formed when two or more atoms transfer electrons.
ionic bonding

Alkali metals will always ionize to form ions with a ____ charge.
+1
Rank the types of bonds possible in covalent bonding from weakest to strongest.
single, double, triple
Does Li2O contain ionic or covalent bonds?
ionic
Why do ionic bonds form between metals and nonmetals?
The big difference in electronegativity means the nonmetal can completely steal the metal's electron
If an atom loses an electron, then that atom will become ____ charged.
positively charged

Halogens always ionize to form ions with a ____ charge.
-1
Up to how many covalent bonds can form between 2 atoms?
3
(triple bond)
Would Cl2 have a nonpolar covalent bond or polar covalent bond?
nonpolar covalent bond
In a polar covalent bond, there will be an uneven distribution of charge. This means part of the molecule will be more negative than other parts. Would it be more negative towards the more electronegative atom or less electronegative atom?
More electronegative
If an atom gains an electron, then that atom will become ____ charged.
negatively charged

Alkaline earth metals always form ions that have a ____ charge.
+2
What is the difference between polar and nonpolar covalent bonds?
Polar is unequal sharing while nonpolar is equal sharing.
Would HBr have a polar covalent bond or nonpolar covalent bond?
polar covalent bond
How do you draw ionic bonds between Lithium & Fluorine in Lewis dot structures?

Which electrons are responsible for the reactivities of the elements?
valence electrons
outermost electrons
electrons in outermost shell
Why do the atoms stay together after transferring electrons?
They're oppositely charged, so they attract each other.
Why do nonmetals share electrons instead of transferring them?
They're close in electronegativity values, so neither can completely overpower the other.
Would H2O be polar or nonpolar?
polar
How do you draw covalent bonds between Carbon & Oxygen in Lewis dot structures?
