Valence Electron

• Electrons in the outermost orbit

  are used to bond with other atoms

• Atoms tend to gain, lose or share electrons to fill their outmost energy level with 8 valence electrons

• A positively charged ion

• A negatively charged ion

Octet Rule

• Electrons in the outermost orbit

  are used to bond with other atoms

• Atoms tend to gain, lose or share electrons to fill their outmost energy level with 8 valence electrons

• A positively charged ion

• A negatively charged ion

Cation

• Electrons in the outermost orbit

  are used to bond with other atoms

• Atoms tend to gain, lose or share electrons to fill their outmost energy level with 8 valence electrons

• A positively charged ion

Anion

• Electrons in the outermost orbit

  are used to bond with other atoms

• Atoms tend to gain, lose or share electrons to fill their outmost energy level with 8 valence electrons

• A positively charged ion

• A negatively charged ion

Polyatomic Ion

• When more than one element groups together and has a charge

  Ex: OH^- Hydrogen ion

• Forces that hold atoms together within a molecule (chemical bonds)

  3 types: ionic, metallic, covalent

• Metallic Bonding: the outermost electron shells overlap creating a ____ and positive ion. AKA Delocalized

• Combo of 2 or more metals

Intramolecular Bonding

• When more than one element groups together and has a charge

  Ex: OH^- Hydrogen ion

• Forces that hold atoms together within a molecule (chemical bonds)

  3 types: ionic, metallic, covalent

• Metallic Bonding: the outermost electron shells overlap creating a ____ and positive ion. AKA Delocalized

• Combo of 2 or more metals

Sea of Electrons

  Ex: OH^- Hydrogen ion

• Forces that hold atoms together within a molecule (chemical bonds)

  3 types: ionic, metallic, covalent

• Metallic Bonding: the outermost electron shells overlap creating a ____ and positive ion. AKA Delocalized

Alloy

• When more than one element groups together and has a charge

  Ex: OH^- Hydrogen ion

• Forces that hold atoms together within a molecule (chemical bonds)

  3 types: ionic, metallic, covalent

• Metallic Bonding: the outermost electron shells overlap creating a ____ and positive ion. AKA Delocalized

• Combo of 2 or more metals

Substitutional Alloy

• Atoms of the original metal are replaced by other metal atoms of the same size

  Ex: Brass

• The small holes in a metallic crystal are filled with smaller atoms

  Ex: Steel

• The atoms share a single pair of electrons

• The atoms share 2 pairs of electrons

• The atoms share 3 pairs of electrons

Interstitial Alloy

• Atoms of the original metal are replaced by other metal atoms of the same size

  Ex: Brass

• The small holes in a metallic crystal are filled with smaller atoms

  Ex: Steel

• The atoms share a single pair of electrons

• The atoms share 2 pairs of electrons

• The atoms share 3 pairs of electrons
