Periodic Table Review Worksheet Answers

ANSWER HEY I. ​PERIODIC TABLE REVIEW 1. Color on the periodic table below where the metals are and where the nonmetals are. Shoehorning 2. Label on the table above which of the metals are transition metals (metals with variable charge). Hint: the short columns in the middle generally have variable charge, except for zinc (Zn). Zinc always has +2 charge. Label these “short” columns. O 3. Metals always form (circle one answer): cations / anions O Nonmetals always form (circle one answer): cations / anions 4. Mark on the highlighted columns of the periodic table below what charge ions originating from that column will have. + I 1- 2 +3 - 3 - 2 - 1 ktBToEsnAog→ II. ​NAMING BINARY COMPOUNDS a. Naming a ​metal with consistent charge​ + a nonmetal Name of metal + ROOT of nonmetal + “ide.” Write the formula and name of the compound that will be formed between these elements: " Al and S 'S AP Ahs aluminum sulfide Formula: _______________________ Name: ______________________ - , H and F HF Formula: _______________________ Name: ______________________ hydrogen fluoride Ca and N → nitride Ca "N3 calcium Cask Formula: _______________________ Name: ______________________ - Zn and O aide zn" OZ → ZnO Formula: _______________________ Name: ______________________ - zine b. Naming a ​metal with variable charge​ + a nonmetal chromium Same as before, except we add a roman numeral after the metal with the variable charge. Write the systematic name of the compound: Formula: CrS 2- sulfide ( It ) Name: ________________________________ Formula: FeCl​3​ iron chloride (E) Name: ________________________________ Formula: Cu​2​O I aide Name: ________________________________ copper ( ) Write the formula of the compound: ARCHAIC WAY : Snfz Formula: _______________________ Name: Tin (II) fluoride FeBr3 Formula: _______________________ Name: Iron (III) bromide " " OUS " IC " IS HIGHER IS LOWER CHARGE CHARGE Ex . FERROUS = " Fe . . FERRIC = Fe " 🎡👫 🎡👫🕺 c. Naming nonmetals with nonmetals Prefix + name of first nonmetal + prefix + name of second nonmetal. Whichever element is leftmost or lowest on the periodic table is read first. Don’t put “mono” on first element. Write the systematic name of the compound: Formula: BCl​3​ Formula: S​2​F​10​ Boron trichloride Name: ________________________________ deca Name: ________________________________ fluoride disulfwe Write the formula of the compound: I Formula: _______________________ 409 Name: Tetraiodine nonoxide d. Naming binary acids in water. When HF, HCl, HBr, or HI are in water, we can give them acid names. “Hydro” + root of nonmetal + “ic” + “acid.” hydrofluoric acid Acid name (in water) of HF: ________________________________ hydrogen fluoride Anhydrous name of HF: ________________________________ Acid name (in water) of HCl: ________________________________ hydrochloric acid Anhydrous name of HCl: ________________________________ hydrogen chloride Acid name (in water) of HBr: ________________________________ hydro bromic acid bromide Anhydrous name of HBr: ________________________________ hydrogen Acid name (in water) of HI: ________________________________ hydro iodic acid Anhydrous name of HI: ________________________________ hydrogen iodide III. ​NAMING COMPOUNDS CONTAINING POLYATOMIC IONS MEMORIZE THESE!!!!!!!!!!! Write the name of the cation + the name of the anion. Formula: ZnCrO​4​ chromate zinc Name: ________________________________ calcium Name: ________________________________ sulfate Formula: CaSO​4​ Formula: NH​4​OH ammonium Name: ________________________________ hydroxide - " Cu Cuz ( ASO 4) ( As 0413 Formula: _______________________ → " Formula: ( z Name: Copper (II) arsenate " → Ca Croy Ca Croy ) _______________________ Name: Calcium chromate IV. NAMING POLYATOMIC ACIDS 😡👯 " fight " " us 🍵🤢 ate . . . ich " Name these acids: Formula: H3PO4 acid Name: ______________________________ phosphate phosphoric Formula: H2SO3 sulfurous acid sulfite Name: ______________________________ Formula: H2CO3 acid carbonic carbonate Name: ______________________________ - → → → Formula: HIO3 Name: ______________________________ Formula: H2NO2 nitrous acid nitrite Name: ______________________________ Formula: HClO Name: ______________________________ Formula: HNO3 nitric acid nitrate Name: ______________________________ × → → Formula: HClO4 Name: ______________________________ Formula: H2SO4 Name: ______________________________ sulfuric sulfate → acid Toga (ACIDS WITH EXTRA OXYGEN) ACIDS V. ​NAMING OXY-ACDIS Reference the polyatomics table again, and name the following. acid Formula: H​3​PO​3 Acid Name: ______________________________ phosphorous Formula: H​3​PO​2 acid Acid Name: ______________________________ hypaphasphauous Formula: H​2​CO​4 acid Acid Name: ______________________________ percarbonie Formula: H​2​CO​2 acid carbonous Acid Name: ______________________________ V.
