2. What Determines an element’s chemistry?
Valence Electrons – The number of electron’s in an element’s highest electron shell.
Helps to determine the chemical properties of an element.
Electron Dot Diagrams – Show the number of valence electron’s for an element.
Chemical Bond – Force of attraction that holds atoms together.
Results from the electron arrangement of two or more elements

Chemical Bonds

5. Ionic Bonds Ionic Bonds: form when 2 or more elements combine.
One elements GAINS electrons
One element LOSES electrons
Ions are charged atoms because the number of protons is not equal to the number of electrons.
Positively Charged Ions – have more Protons than Electrons (Sodium)
Negatively Charged Ions – have more Electrons than Protons (Chlorine)
