Define
Define the term "Chemical Formula"
What is "Something used to tell what element and how many of each element are in a unit of a compound."
Name the Word: Atoms or molecules that have a charge due to having lost or gained electrons
What is "Ion"
Why do elements for compounds
What is "So they can be stable/balanced"
How do you determine a chemical formula from an ionic compounds name?
(Ex. How do you know that sodium chloride is NaCl)
What is finding their charges from the periodic table or Roman numerals, then use the criss-cross method to make the charge neutral
How do you determine a chemical formula from a covalent compounds name
What is using Greek prefixes (di-, tri-, tetra-) to find the number of atoms for each nonmetal element, write the element symbols in the order they appear, use the prefix for the first element (omit 'mono-'), and add '-ide' to the second element's name
Define the term "Chemical Bond"
What is "Oxidation Number"
What elements never form compounds and why
What is "Noble Gases". They are already stable
How do you determine the ionic compounds name from the chemical formula
What is stating the metal cation first (as written), then the nonmetal anion with an "-ide" ending
How do you determine a covalent compounds name from a chemical formula
What is using Greek prefixes (mono-, di-, tri-, etc.) for the number of atoms, name the first element as is, change the second element's ending to "-ide," and omit the "mono-" prefix for the first element if there's only one atom
Define the term "Ionic Bond"
What is "A bond that consists of a metal and a nonmetal"
Name the Word: Positively charged ions; atoms or molecules that have lost e-
What is "Cation"
What is the difference between ionic and covalent bonds
What is Ionic bonds involve the transfer of electrons from a metal to a nonmetal, while covalent bonds involve the sharing of electrons between two nonmetals
What is the polyatomic ion exception to naming ionic compunds
What is the rule that you don't change the ending to -ide
What number does the prefix di- mean
What is 2
Define the term "Covalent Bond"
What is "A bond that consists of two nonmetals"
Name the Word: Negatively charged ions; atoms or molecules that have charged electrons
What is "Anion"
What are 2-3 characteristics of an ionic compound
What are high melting/boiling points, are hard but brittle crystalline solids, and conduct electricity when melted or dissolved in water, but not as solids
What is the transitional metal exception to naming ionic compounds
What is transitional metals need Roman numerals.
What number does the prefix tetra mean
What is 4
Define the term "Octet Rule"
What is "Atoms will gain, lost, or share electron in order to have 8 electrons in outer energy shell"
Name the Word: Two or more elements are covalently bonded
What is "Molecule"
What are 2-3 characteristics of a covalent compound
What are low melting/boiling points, are poor electrical conductors, and often exist as gases, liquids, or soft solids at room temperature due to weak intermolecular forces, though they can vary in water solubility
What number does the prefix Nona stand for
What is 9
