THE ATOM

Protons (+)

Neutrons (0)

Electrons (-)Notice the size

Why are VALENCE ELECTRONS important?1. Atoms want to be stable (Nobel Gas Configuration)

2. Atoms will steal/share valence electrons to do this

3. When valence electrons are removed or added, atoms form or break bonds and a CHEMICAL REACTION occurs

VALENCE ELECTRONS (ELECTRONS ON THE LAST RING)

Few ve- = more likely to give them away

Lots of ve-= less likely to give them away

Lewis dot structures show an elements valence electrons

and can help you with showing ATOMIC BONDING

IS IT A CATION OR AN ANION?

Chlorine

Remember electrons have

NEGATIVE (-) charges

IONIC• Bond that forms when one atom gives away a valence

electron to another atom

• Occurs between METALS and NON-METALS

BALANCING EQUATIONS

Balance an equations so that the reaction obeys the Law of Conservation of Mass

Steps/Rules:

1. Make a chart to count the atoms in your reactants and your products *If an equation is unbalanced, you MAY NOT change the subscript. You are only allowed to change the coefficient out in front.

2. Count how many atoms you have for each element in EACH compound BEFORE you start placing coefficients out in front.

3. If you do not put a coefficient in front of a compound, we treat it as a 1.
