Periodic Table Test – Study Guide What state of matter are almost all metals in at room temperature? Solid, liquid, or gas? What state of matter are nonmetals in at room temperature? Solid, liquid, or gas? What is similar for elements in a group/family on the periodic table? (2 things) number of valence e-, properties/reactivity What kind of ion is formed when an atom gains an electron? negative anion Loses an electron? positive cation Classify the following as either metals, nonmetals, or metalloids. Mg H C Si Cu O H Li Sn Ge B Ne M NM NM Md M NM NM M M Md Md NM Who published the first periodic table? Mendeleev How did Dobereiner classify elements? similar properties How did he place these elements together? in triads (groups of 3) with increasing atomic mass Why did Mendeleev leave blank spaces on the periodic table? for undiscovered elements What does the modern periodic law say? chemical and physical properties repeat in a regular pattern when elements are arranged in order of increasing atomic number Which elements are the most unreactive? noble gases Which of the following are transition elements? Mg H Cl Cu Al Ni Ga How many valence electrons are there for Group 1 elements? Group 2? Group 14? Group 16? 1 2 4 6 What are horizontal rows on the periodic table called? periods What are columns on the periodic table called? groups or families Classify these properties as either for metals or nonmetals. Malleable ductile M M high melting points M brittle NM lustrous M gases flexible NM M conductors M insulators NM Which groups are transition metals? Halogens? Alkaline earth metals? Alkali metals? 3-12 17 2 1 Which elements are used to make semiconductors? metalloids – specifically Si and Ge Which block on the periodic table contains the most active metals? S, p, d, or f? Label the s, p, d, and f blocks. Fill in the correct trend for each thing. (increasing or decreasing) Atomic radius / Size increase Ionization energy decrease Electronegativity decrease Metallic character increase Metal reactivity increase Nonmetal reactivity decrease S Atomic radius / Size decrease Ionization energy increase Electronegativity increase Metallic character decrease nonmetal reactivity - increase P D F Define ionization energy. Amount of energy required to remove an electron Define electronegativity. Ability for an atom to attract electrons in a bond Which one is larger? Na or Li S or Mg What are positive ions called? cations What are negative ions called? anions F or F-1 Na or Na+1
