Period ______ Date __________________
Covalent bond =
Molecule =
Atoms combine to become more __________________________.
An atom becomes more stable when it fills it’s outer energy level with the ______________
of electrons it can hold.
Trying to be more stable… two hydrogen would prefer to be together than alone!
2 Hydrogen atoms
Making water =
Hydrogen
Making Methane=
Oxygen
Hydrogen
Carbon
How many electrons can a carbon atom share? (Hint – how many empty spaces?)
Draw your own hydrogens bonded to the empty spots on the carbon to form Methane.
1
What is an ion?
Ionic bond =
Ionic bonds are not sharing, one takes, the other loses.
Compound =
Making salt =
Sodium Atom
11 electrons
Chlorine Atom
17 electrons
How many electrons would sodium need to
fill its outer energy level?
How many electrons would chlorine need to
fill its outer energy level?
Is it easier for this atom to gain or lose
an electron?
Is it easier for this atom to gain or lose
an electron?
Ions
Who gained the electron?
They are the ion - ! Write its symbol here:
Who lost the electron?
They are the ion + ! Write its symbol here:
