How is the periodic table organizedThe rows are called periods with shells that increase in the amount as you go further down the table. The rows are groups and depending on the group the valence electrons have a certain amount. Each type of element (metals. non-metals, metalloids).What is atomic radius?The radius of an atomWhat is ionization energy?The amount of energy needed to remove a valence electronDo metals or non-metals have a higher ionization energy? Why?Non-metals have a higher ionization energy because non-metals are trying to pull electron off of other atoms not lose electronsWhy does ionization energy decrease as you go down a group?The attraction of the valence electrons to the nucleus decreases as the valence shells get further awayWhat is electronegativity?How much the atom wants to gain an electronDo metals or non-metals have a higher electronegativity? Why?Non-metals have a higher electronegativity because the distanceWhat is the octet rule?Every valence shell(except Helium which has one valence shell so there is only two valence electrons) want 8 valence electronsWhat is the difference between an element and a compound?An element cannot be separated or made of something else. A compound is two atoms joined together.Why do atoms bond? Hint: think about the valence electronsAtoms bond together to have a full valence shellWhat types of elements for ionic bonds?Metals and non-metals form ionic bondsWhy are ions important in forming an ionic compound?Ions are important because the atom is either losing or gaining electronsWhat do ionization energy and electronegativity have to do with ionic bonds? Hint: think about what types of atoms (metals and non-metals) want to gain/lose electrons.Ionization energy and electronegativity have to do with which electrons are going to be pulled awayWhat do oxidation numbers tell you?Whether the element gained or lost an electronWhat is a cation and an anion? What types of elements (metals or non-metals) form each?A cation is an element with a positive charge and is a metal. Anions are non-metals and have a negative charge.Explain how to name an ionic bond.The name of the metal goes first then the non-metal with prefixes to tell how many atoms are in the compound.Name the following ionic compounds.LiCl Lithium monochloride CaF2 Calcium difluoride Al2O3 Dialuminum trioxideUse the swap and drop method to write the formula from the name of the ionic compounds:Aluminum Oxide AlO Calcium Nitride CaN Potassium Sulfide KSList 2 everyday substances that are held together by ionic bonds.Salt and waterDescribe a covalent bond. Include the types of elements involved and the behavior of the electrons in a covalent bond.Covalent bonds share valence electrons and is between two non-metalsExplain how to name a covalent bond.The element farthest to left or bottom goes first with a prefix, then the element farthest to the top or right gets a prefix and "ide"Name the following covalent compounds:P2Cl6 Diphosphorus Hexachloride CO2 Carbon dioxide CO Carbon monoxide SBr4 Sulfur TetrabromideList 2 everyday substances that are held together by covalent bonds.Water and diamondWhy don't noble gases form ionic or covalent (chemical) bonds?They have a full valence shell
