PAP Atoms & The Periodic Table

Periodic Table Periods and Groups Element Table Use your periodic table to complete the following chart by determining the element that matches the statement. Clue Element Identify the element with 79 protons Gold Identify the element with 4 valence electrons and the least mass Carbon Identify the metalloid in period 3 with more protons than sodium and fewer valence electrons than chlorine Silicon Identify the metal in period 3 that is more reactive than magnesium (Mg) Sodium Identify the nonmetal in period 4 that is more reactive than selenium (Se) Bromine Identify a nonmetal in period 3 that is less reactive than sulfur (S) Phosphorus OR Argon Identify the element with 47 protons Silver Identify the element in period 5, group 17 (7a) Iodine Identify the element with 5 valence electrons in period 4 Arsenic Identify the element with 3 energy levels and 2 valence electrons Magnesium Identify the element with 5 neutrons Beryllium Identify the element that is more reactive than sulfur (S) and has one less proton than argon (Ar) Chlorine Identify the element that is non-reactive (inert) with 3 energy levels Argon Identify a nonmetal with 1 valence electron Hydrogen Identify the nonmetal in period 2 that is more reactive than nitrogen (N) and less reactive than fluorine (F) Oxygen Identify the least reactive metal in period 3 Aluminum Identify the metalloid in group 13 Boron Identify the noble gas with 2 valence electrons Helium Identify the metal in the 4th period that is more reactive than calcium (Ca) Potassium Identify a metalloid with 5 valence electrons Arsenic OR Antimony Identify the element that has 6 valence electrons with 3 energy levels Sulfur Identify the element that has 5 valence electrons and 2 energy levels Nitrogen Identify the Lanthanide with the least mass Lanthanum Identify the element that has more valence electrons than fluorine and fewer energy levels than sodium (Na) Neon Identify this element Aluminum Identify this element Lithium Is this element classified as a metal, nonmetal, or metalloid? Metal Metalloid Nonmetal How many valence electrons does this atom have? 2 5 8 10 15 16 31 What period is this element in? 1 2 3 4 5 6 7 What group # is this element in? 1 2 13 14 15 16 17 18 What is the group number that nitrogen is in? 1 2 13 (3a) 14 (4a) 15 (5a) 16 (6a) 17 (7a) 18 (8a) What is the group number that this element is in? 1 2 13 (3a) 14 (4a) 15 (5a) 16 (6a) 17 (7a) 18 (8a) Select all elements that have similar chemical properties to the element pictured. Sulfur Selenium Tellurium Polonium Carbon Nitrogen Why is this element considered unreactive or inert? Because it has 2 shells Because it has 2 electrons on the inner shell Because the outer electron shell is full Because the neutrons are full Which of the following is a method for calculating the number of neutrons in an atom? Atomic mass is equal to neutrons Atomic mass minus atomic number is equal to neutrons Atomic number is equal to neutrons Atomic number minus the number of valence electrons is equal to neutrons What is the group number that this element is in? 1 2 13 (3a) 14 (4a) 15 (5a) 16 (6a) 17 (7a) 18 (8a)
