- Use the periodic table to classify each element as a main-group metal, a transition metal, an inner-transition metal, a metalloid, or a nonmetal. Main-group metal tin platinum Transition metal vanadium Inner-transition metal uranium Answer Bank Metalloid boron lithium Nonmetal carbon argonarrow_forwardDoes any element with Z ≤ 92 match the description? An element in period 6 and group 6A.arrow_forwardHi, can someone pls tell me if these answers are correct and help me find the answers to the ones I didn't know, thanks ?arrow_forward
- 3. Classify each of the following elements as a noble gas, a representative element, a transition element, or an inner-transition element. Also state whether the element is paramagnetic or diamagnetic: (a) potassium; (b) phosphorous; (c) promethium; (d) platinum; (e) krypton.arrow_forwardthe distinction between metals and nonmetals is really not a clear one. Some elements called metalloids are intermediate in their properties. Which of these elements would you reclassify as metalloids? What other elements in the periodic table would you expect to be metalloids?arrow_forwardhave varied physical properties and are found in many different compounds. Nonmetals Metals Metalloidsarrow_forward
- 4. Identify the Z + 8 element for Si.arrow_forwardWhen a nonmetal oxide reacts with water, it forms an oxoacid with the same oxidation number as the nonmetal. Give the name and formula of the oxide used to prepare each of these oxoacids: (a) hypochlorous acid; (b) chlorous acid; (c) chloric acid; (d) perchloric acid; (e) sulfuric acid; (f ) sulfurous acid; (g) nitric acid; (h) nitrous acid; (i) carbonic acid; ( j) phosphoric acid.arrow_forward2. The elements vary from metals through metalloids to nonmetals. They form halides in oxidation states +5 and +3 and the hydrides are all toxic gases. Identify this group of elements.arrow_forward
