| 1/2 of the distance between nuclei of two atoms of the same element in a diatomic molecule. | Atomic Radius |
| The energy needed to remove the attraction of the nuclear charge and remove an electron (from a gaseous atom) is called. | Ionization Energy |
| The reduction of attractive force of the nucleus for the outer electrons caused by electrons in energy levels between nucleus and the outer electrons. | Electron Shielding |
| A positively charged ion | Cations |
| A negatively charged ion | Anions |
| Are the most reactive nonmentals | Halogens |
| The ability of an atom to pull on the electron | Electronegativity |
| Groups labeled with an "A" are the ____________ | Representative Elements |
| Instead of ordering the elements by increasing atomic mass, Henry Moseley arranged them by ________ | Atomic Number |
| What is the meaning of the word Periodic? | Means to exhibit a repeating pattern |
| One way to clarify the elements on the periodic table is by the ________ and __________ to which they belong. | Period - Group |
| Are the vertical columns on the periodic table, numbered 1 to 8 | Groups / Families |
| The groups labeled with B are the ___________________ | Transition Elements |
| What are the name of the elements under the Group 2A? | Alkaline Earth Metals |
| These elements are harder, denser, stronger than alkali metals they also have higher melting point | Alkaline Earth Metals |
| Three types of Bonds | Ionic, Metallic and Covalent |
| Three types of Covalent bond | Single bond, Double bond and Triple bond |
| Properties of Ionic Bonding | Hard, High Meting Boiling Point and Brittle |
| The kind of bonding between metallic elements which the valence electrons can move freely from an atom to another. | Metallic Bonding |
| Properties of Metallic Bond | High Melting and Boiling points - Electrical and heat conductor |
| Example of metals elements | Lithium, Magnesium and Sodium |
| These bond are usually formed between non-metals elements | Covalent Bonding |
| Three types of Covalent Bonding | Single Bond, Double Bond and Triple Bond |
| This type of Covalent bond is formed when two atoms bond and share a single pair of electron | Single Bond |
| T or F In triple bonds, their valence electrons are associated with how many pairs they can create. | True |
| Are the weaker bonds, they are formed when parallel orbitals overlapped to share the electrons | Pi Bonds |
| A compound that results when a metal reacts with a non-metal to forms ions called Cations and Anions | Ionic Compound |
| Binary means __________ | Two Elements |
| Ionic means ____________ | A metal and a non-metal (or cation and anion) |
| Ternary means __________ | Three different elements |
| Composed of molecules in which elements share electrons | Molecular Compounds |
| Electronegavity (EN) difference > 2.0 | Ionic bonds |
| EN difference is between .21 and 1.99 | Polar covalent bonds |
| EN difference is < .20 | Non-polar covalent bonds |
| It is a chemical change in which one or more substances are destroyed, and one or more new substances are created | Chemical Reaction |
| The numbers within the formula | Subscripts |
| Single uncombined element replaces another element in an Ionic compound | Singe Displacement Reaction |
| There are two reactants and two products | Single Displacement Reaction |
| General Formula of Single displacement reaction | A +BC --- AC + B |
| Parts of 2 acqueous ionic compounds switch places to form two new compounds | Double Displacement Reaction |
| General Formula of Double displacement reaction | AB + CD --- AD + CB |
| Two or more simple substances (the reactants) to form a more complex substance (the product) | Synthesis Reaction |
| General Formula of Synthesis reaction | A + B --- AB |
| Produces two or more elements and or/ compounds | Decomposition Reactions |
