Final Jeopardy The negatively charged part of the atom. electron 1 pt The smallest part that an element can be broken down to and retain its physical and chemical properties. atom 2 pts The name given to the group of elements that are the most stable. Noble gas 3 pts Atoms that have the same number of protons but different numbers of neutrons Isotope. 4 pts Properties of elements change periodically with the elements’ atomic number according to this. Periodic law 5 pts This part of the atom has a positive charge. proton 1 pt This part of the atom has a negative charge. electron 2 pts This part of the atom is in the center and includes protons and neutrons. nucleus 3 pts Draw a Bohr model for boron (B). 4 pts Is it possible for carbon (C) to have 7 protons? Explain your answer. No. If it has 7 protons it is a different element. It is nitrogen (N). 5 pts What is the name of the element with the symbol Cl? Chlorine 1 pt How many protons are in an atom of magnesium (Mg)? 12 2 pts The atomic number of an atom, as it appears on the periodic table of elements, is the same as the number of ______. Protons and electrons 3 pts An atom of cesium (Cs) has 55 protons, 55 electrons and 78 neutrons. What is its atomic mass? 133 4 pts An atom has 21 electrons. How many neutrons does it have? 24 5 pts The horizontal rows on the periodic table are called ________. Periods. 1 pt The vertical columns on the periodic table are called ________. Groups or families 2 pts Most of the elements on the periodic table are to the left of the zigzag line and are classified as this. metals 3 pts Lithium (Li), sulfur (S), nickel (Ni) or germanium (Ge). Which of these is a metalloid? Germanium (Ge) 4 pts What do all the elements in group 17 have in common. Similar reactivity or 7 valence electrons. 5 pts The center of the atom is made of these. Protons and neutrons 1 pt Metalloids have characteristics of both of these. Metals and non-metals 2 pts Metals can be described as good conductors of these. Heat and electricity 3 pts These 2 groups on the periodic table of elements are the most reactive. Group 1 and 17. or The alkali metals and halogens 4 pts How does ionization energy change as you move from top to bottom of the periodic table? Ionization energy tends to decrease from top to bottom within a group 5 pts Final Jeopardy Category Organization of the Periodic Table Write your point wager on your board now. You can wager any amount from 0 points to your total points. The elements in group 18, the Noble Gasses, are grouped together because they are stable. Why are they stable? Their outer electron shell is full.
