![]() However, the inhabitants of the planet have different names and symbols for them. The planet is composed of the same elements as Earth. (For the sake of this activity we are going to agree that there is intelligent life on Planet G.) The intelligent life on Planet G has made contact with scientists on Earth Planet G’s languages have been translated, and scientific information has begun to be exchanged. The periodic law is believed to be universal so that it should hold true not only on Earth but also throughout the universe, including the newly discovered planet…Planet G in the Gliese 581 system. Henry Moseley later arranged the periodic table according to the increasing atomic number. The first periodic table was arranged by Dmitri Mendeleev according to atomic mass in such a way that elements with similar properties were grouped together. The periodic table is one of the most useful tools used by chemists. Background Information: Read the following before proceeding. The chemical formula for sodium chloride (salt) is _. Electrons in the last energy level are called _ electrons. Diatomic elements such as oxygen gas have _ atoms. A period 3 element would have _ energy levels. Groups or families of elements run _ (horizontal or vertical). Asiago (A) and Ricotta (Ri) both areĪlkali earth metals too! Asiago has 20 electrons.Planet G Periodic Table Pre-lab Questions: Answer the following questions before proceeding. Manchego (Mo) has the fewest electrons than any other alkali earth metal.Provolone (Pr) has the lowestĪtomic mass, while Gruyere (Gr) has the highest. Provolone (Pr), Gruyere (Gr) and Gorgonzola (Go) belong in the Nitrogen Family.Neufchatel (Nf) has 8 protons, and its neighbor in Period 3 is Camembert (Ca).Whereas Marscapone is the basis for all life and has a mass number of 12 when not an isotope. Edam (Ed), Havarti (Ha) and Marscapone (Ma) all have 4 valence electrons.(R) is the only metalloid in the Boron family. Limberger (Li) and Munster (Mu) are both metals in the Boron Family.Roquefort (Ro) is in the same group as Mozzarella.(Br) is even more reactive than Mozzarella, Brie in Period 4 Mozzarella (M) is the reactive metal that reacted with water in the video, and is in the alkali metal family.Fontina is in the same period as Cheddar. Casero has the lowest atomic number, whereas Bleu has the highest They do not react with anyone elseīecause they have 8 valence electrons. Casero (Co), Bleu (B), Chevre (C) and Fontina (F) are nonmetal nobility.Swiss (S) is the lightest nonmetal in the chart.Cheddar (Ch), Gouda (G) and Parmesan (Pa) are halogens.Alien Periodic Chart - Directions: Read the clue and place the alien symbol in the corresponding box! Aġ 2 3 4 5 6 7 8 S Co Ro Mo R Ma Pr Nf G C M Ri Li Ha Go Ca Ch F Br A Mu Ed Gr Be Pa B How can you tell the identity of any atom? (1 point) Number of PROTONSġ5. What is an isotope? (1 point) An atom with a different number of neutrons 14. For the questions below and based on the information provided, fill in the missing information.Which element would have the highest ionization energy? Helium Which element would have the smallest atomic radius? Helium 10. Two characteristics of Metals are malleable, ductile, good conductors of heat and electricity 9. Two Characteristics of Non-metals are not good conductors of heat or electricity, not malleable, etc. The atomic number tells you how many protons (and electrons if neutral) there are in an atom. How many valence electrons does Bromine have? 7 6. What element is at period 3, group 8A? Argon 5. Which element would have the highest electron affinity? Fluorine 4. What do elements in the same group have the same number of? Valence electrons 3. Elements that have the properties of both metal and non-metals are metalloids.
