PPT-IONS! How they are formed

Valence Electrons Valence Electrons of an atom are the electrons that are in the outermost s and p sub shells ONLY S AND P To determine how many electrons are in your valence shell look at where your element is on the periodic table. Adduct ionAn ion formed by interaction of two species, usually an ion and a molecule, and often within an ion source, to form an ion containing all the constituent atoms of one species as well as an - To be able to explain how mountains are formed . Plate Tectonics . The Earth's surface is made up of a series of large plates (like pieces of a giant jigsaw puzzle) called tectonic plates. . These plates are in constant motion travelling at a few centimetres per year. This is called continental drift.. and stuff like that.. A complex ion is the exception to a rule.... It is an ionic compound that has an overall charge.. Complex ions are identified using square brackets. [ ]. Complex Ions. Are soluble.. _____ . is a chemical compound that increases the concentration of ________________ ions (H. +1. ), in aqueous solution. The hydrogen ions are attracted to the water molecules in an aqueous solution and form . SNC2D. Polyatomic Ions. Polyatomic ions are groups of atoms that tend to stay together and carry an overall ionic charge. The ion is typically held together with covalent bonds. The polyatomic ion is capable of bonding with other ions. Learning objective: To understand how unknown compounds can be identified.. Must: Explain what a precipitate is – E. Should: Be able to use different tests to identify metal and non-metal ions – C. Many ions are monoatomic BUT. Most ions are polyatomic (>1 atom). 330.07.01b.Names & Formulas - Polyatomic. There are . five common polyatomic. ions:. nitrate NO. 3. –. carbonate CO. 3. 2– . How elements become charged. How elements become charged. ION – A charged atom. All elements on the periodic table are NEUTRAL because they have the same number of . protons (+) and electrons (-). What are we testing to find?. This test is to confirm the presence of sulphate ions.. Sulphate ions are negatively charged (SO. 4. 2-. ) therefore they are anions.. How do we do the test?. Place the sample solution in a test tube.. Types of bonds. Ionic bonding. results from electrostatic attractions among ions, which are formed by the . transfer. of one or more electrons from one atom to another.. Covalent bonding. results from . MACROSCOPIC SCALE. Elements combine to make compounds.. ATOMIC SCALE. Atoms combine to make molecules, or extended structures.. What we’ll cover…. Compound Formulas. Ions. Monatomic. Polyatomic.
