Atoms become more stable when they have a full set of valence electrons. For most atoms, how many electrons are needed for a full set?
8
How many valence electrons does Hydrogen need to have a full set of valence electrons?
2
What is the octet rule?
most atoms need 8 valence electrons to be stable
In what type of bond are electrons shared between atoms?
covalent bonds
In what type of bond are electrons completely transferred from one atom to another?
ionic bond
T/F: Energy is stored in covalent bonds.
true
What is electronegativity?
strength that atoms attract electrons
T/F: Different kinds of atoms, like Carbon and Oxygen, can have different levels of electronegativity. This can affect how they share electrons in covalent bonds.
true
Why do atoms bond with one another?
to be more stable; have a full set of valence electrons (typically an octet)
What type of bond is made when 2 electrons are shared between two atoms?
ionic bond
single bond
double bond
triple bond
What type of bond is made when 4 electrons are shared between two atoms?
triple bond
ionic bond
double bond
single bond
What type of bond is made when 6 electrons are shared between two atoms?
double bond
triple bond
single bond
ionic bond
How many bonds does Carbon want to make?
4
How many bonds does Hydrogen want to make?
1
How many bonds does Oxygen want to make?
2
Rank the covalent bonds (single, double, triple) in order from weakest to strongest.
single bond, double bond, triple bond
