A + (positive) charge states that (an) electron(s) have been lost, while a- (negative) charge shows that electrons have been gained.  \nIonic Charges of the Periodic Table:  \n\n| Group \\# | Valence Electrons | Electrons Needed To Lose or Gain | Ionic Charge |\n| --- | --- | --- | --- |\n| 1 | 1 | -1 | +1 |\n| 2 | 2 | -2 | +2 |\n| 13 | 3 | -3 | +3 |\n| 14 | 4 | -/+4 | +/-4 |\n| 15 | 5 | +3 | -3 |\n| 16 | 6 | +2 | -2 |\n| 17 | 7 | +1 | -1 |\n| 18 | 8 | 0 | 0 |\n\n• Valence electrons are the electrons in the outermost shell of an atom. They are loosely bound and available for compound formation.  \n• The number of valence electrons inan atom is equal to its group number on the periodic table.  \n• For groups 13-18, remove the 1 to get the number of valence electrons.  \n• Atoms like to be stable when forming compounds.  \n• Noble gasses don't form compounds since they're already stable.  \nBohr-Rutherford Diagrams:  \n1. Write the standard atomic notation.  \n2. Calculate the number of protons, electrons, and neutrons (PEN) .  \n3. Draw a circle for the nucleus and write the number of protons and neutrons inside it.  \n4. Draw a larger circle around the nucleus for the first orbital and dot the number of electrons (max of 2) .  \n5. If needed, continue the pattern, however the max becomes 8  \n6. If you’re drawing an ion rather than an atom, make it stable  \nGrade 10 Science — Exam Notes Andrew Abosh  \nFive Special Transition Metals:  \n1. Copper (Cu): 2+, or 1+  \n2. Iron (Fe): 3+, 2+  \n3. Lead (Pb): 4+, 2+  \n4. Tin (Sn): 4+, 2+  \n5. Manganese (Mn): 4+, 2+  \nCompounds:  \n1. Ionic: An ionic bond between a non-metal and a metal, the metal being positive while the non-metal being negatively charged.  \n2. Polyatomic: An ion made up of more than one atom that acts as a single particle. A polyatomic compound is similar to an ionic compound, only different being the polyatomic ion acting as the non-metal.  \n3. Molecular: A substance formed from two or more non-metals.  \nWRITING CHEMICAL FORMULAS FOR IONIC COMPOUNDS  \n1. Write the symbols for each element, the metal being first.  \n2. Write the ionic charges above each symbol.  \n3. Crisscross the numbers downwards, lose the signs, and then write them as subscripts. Do not write the “1”.  \n4. Divide subscripts by the highest common denominator.  \nNAMING IONIC COMPOUNDS  \n1. Name the metal first using the name on the periodic table.  \n2. Name the non-metal second, change the ending of the name to“ide”. If one of the metals is one of the five special ones, state their charge with roman numerals.  \nWRITING CHEMICAL FORMULAS FOR POLYATOMIC COMPOUNDS  \n1. Write symbols for the metal and polyatomic ion, write the metal first.  \n2. Write the ionic charges above each symbol, place brackets around the polyatomic ion.  \n3. Crisscross the numbers downwards, lose the signs and then write them as subscripts. Remove the brackets if the subscript outside is 1.  \n4. Divide the subscripts by the highest common denominator.  \nGrade 10 Science — Exam Notes Andrew Abosh  \nNAMING POLYATOMIC COMPOUNDS  \n1. Name the metal ion first.  \n2. Name the polyatomic ion second. Do no change the ending of a polyatomic ion.  \nWRITING CHEMICAL FORMULAS FOR MOLECULAR COMPOUNDS  \n1. Write symbols for each non-metal element, the element with the smaller group number first.  \n2. The prefix indicates the number of atoms for each element. Write it as a subscript behind the element.  \nNAMING MOLECULAR COMPOUNDS  \n1. Name the first element.  \n2. Name the second element, using the ending“ide”.  \n3. Use the correct prefix to indicate the number of atoms present for each element.  \n\n| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |\n| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |\n| Mono | Di | Tri | Tetra | Penta | Hexa | Hepta | Octa | Nona | Deca |\n\nThe Law of Conservation of Mass:  \nIn any given chemical reaction, th","cbCaiqtw8yKWiW3H","https://ap.wps.com/l/cbCaiqtw8yKWiW3H","pdf",3603034,"English","# Unit One: Chemistry\n## How Ions Are Formed\n## Ionic Charges of the Periodic Table\n## Bohr-Rutherford Diagrams\n## Five Special Transition Metals\n## Compounds and Bond Types\n## Writing Chemical Formulas (Ionic/Polyatomic/Molecular)\n## Naming Chemical Compounds (Ionic/Polyatomic/Molecular)\n## The Law of Conservation of Mass\n## Balancing Equations (Word and Skeleton)\n## Types of Reactions (Synthesis, Decomposition, Displacement, Combustion)","[{\"question\":\"How do ions form, and what do positive and negative charges indicate?\",\"answer\":\"Ions form when electrons move from one atom to another.
