Ions, Ionic Nomenclature, Molecular Compounds, and Metals, Metalloids, and Nonmetals

Ions, Ionic Nomenclature, Molecular Compounds, and Metals, Metalloids, and Nonmetals. What and how are ions formed?. Ions are charged atoms. To become an ion they have to lose or gain an electron. When an atom gains an electron, it gains a negative charge.

Presentation Transcript

  1. Ions, Ionic Nomenclature, Molecular Compounds, and Metals, Metalloids, and Nonmetals

  2. What and how are ions formed? • Ions are charged atoms. • To become an ion they have to lose or gain an electron. • When an atom gains an electron, it gains a negative charge. • When an atom loses an electron, it becomes more positive charge. • How to Draw them…To the board..

  3. Monatomic vs. Polyatomic Ions • Monatomic Ions • S • O • N • Polyatomic Ions • Look at list

  4. Rules for Ionic Compounds • Ionic compounds have one positive ion and negative ion. • What are positive ions called? • What are negative ions called? • When making a compound, the positive charge has to equal the negative charge • The number of ions in a compound are listed as subscripts. • How many Lithium ions are in Li2O? • How many Phosphideions are in Mg3P2?

  5. Rules for Ionic Compounds • Changing the ending of the negative ions to “ide” • What is the nitrogen ion called? • What is the magnesium ion called? • What is MgCl2 called? • When making compounds, the positive ions is listed first.

  6. What is an Ionic Compound? • A compound that is produced from a metal and a nonmetal element reacting. • Sodium Metal and Chlorine (nonmetal) for NaCl • Magnesium Metal and Oxygen for MgO • Iron metal and Nitrogen for FeN

  7. What is a Molecular Compound • A compound that is produced from two or more nonmetals (orange on the periodic table) reacting • Oxygen Gas • Nitrogen Gas • Ozone • CH4 • Hydrogen is a nonmetal. • Molecular Compounds have different Nomenclature Rules.
