Answer the following
12. Four students were asked to complete a table for a science assignment. Each student selected one chemical element from each of four groups in the periodic table and then classified each element as a metal, a nonmetal, or a metalloid. Information About Which table was completed correctly? Some Chemical Elements Group Symbol Classification 10 Ni Nonmetal 14 Metalloid 2 Mg Metal 6 Pb Metal Information About Some Chemical Elements Group Symbol Classification 17 Nonmetal Ca Metal Rb Metal 15 As Metalloid Information About Some Chemical Elements Group Symbol Classification 13 B Metalloid 15 Metal 2 Ra Nonmetal 18 Не Metal Information About Some Chemical Elements Group Symbol Classification 11 Cu Metal 15 Sb Metal 16 Metalloid 2 Ne Nonmetal
Metal ions are named by naming the element and adding the word ion. Metal ions that have variable charge need roman numerals to indicate their charge. These are ALL metals except those in groups 1 and 2, Ag+, Cd2+, Zn2+, and Al3+. Use of roman numerals with these exceptions is considered incorrect. Fill in the blank with the name of the metal ion. Be sure to use the capital letter "i" for your roman numerals (do not use lower case "L" or the number 1).
Consider this ionic isotope. The identity of the element is missing. 39 ? 2+ 20 Which three statements are true? It's yttrium The nuclear charge is 39 It has gained two electrons O It's a cation O It's an anion It has more than 17 neutrons O It's calcium The mass number is 20
