Lewis Dot Structures Bohr Models
1. Know that most scientists believe that matter is made of protons, neutrons and electrons which
are themselves made up of quarks and leptons (electrons). 2. Know that atoms with a different number of protons are different elements (mass, charge, number
of neutrons, number of electrons can vary for each element, but if the number of protons were to change it has now become a different element)
3. Be able to use the periodic table to determine the mass number, family/group, period, number of protons, neutrons and electrons in a neutral atom

An Alien Periodic Table Name_________________
1. The inert gases are mombar (Mb), topspin (Ts), ptumje (O), and Twigauf (Tw). Mombar does not have as many valence e as the other inert gases which have 8. The valence electrons of Twigauf have a principal quantum number of 2. Of the inert gases, topspin has the greatest atomic mass.
2. The alkali metals are laxig (X), kaydjon (Kj), injera (In), and packzil (P). Of the alkali metals, injera has the lowest atomic mass. Packzil is in the same period as topspin.
3. The halogens are roentgreer (A), nemoy (Ny), and trykers (Tk). Nemoy is in the same period as packzil and topspin.
4. The metalloids are Utherfo (Uo), utwwgo (Sd), testudo (T) and tattatt (Tt). Tattatt is the metalloid with the highest atomic mass. Utherfo is the metalloid with the lowest atomic mass. Utwwgo and testudo are in group 4A. T has more protons than Sd. The element called shabbamahz (Sz) is a metalloid by location but has properties that suggest that it is a light metal.
5. The most metallic element on the planet is called laxig (X). The most chemically active nonmetal is called roentgreer (A). The lightest element on the planet is called Moelder (Xf). The heaviest element on the planet is taos (Ta).
6. The chemical makeup of the alien planet’s oceans seems to be similar to the oceans on Earth. When sea water is distilled, the liquid that is boiled off and then condensed has been shown to have molecules consisting of two atoms of Xf and one atom of ruuthye (Ru). The solid that is left behind after the distillation consists mainly of a crystal made up of the elements kaydjon (Kj) and trykers (Tk).
7. The element called dadgummit (D) has only 4 protons in its nucleus. 8. Feelay (Fy) is a black crystal and has 4 electrons in its highest energy level. Both Goldaarp (G)
and mianame (Mi) have atoms with four energy levels. But Goldaarp is less metallic than mianame.
9. Magnificon (M), goldy (Mn) and tattatt (Tt) are all members of group 15. Goldy has fewer total electrons than magnificon.
10. Phartz (Ph), Toto (To) and ruuthye (Ru) all gain 2 electrons when forming ions. Ruuthye is diatomic. Toto has a lower atomic number than Phartz.
11. The element oneutron (On) tends to lose 3 electrons when forming an ion. The elements lambda (L) and toggle (Jy) both lose 2 electrons. Toggle loses them from its fifth energy level, while lambda loses them from its third.
Procedure: Fill in the table below with the correct alien symbol for each element.

Periodic Stick People Name_____________ Directions:
1. Obtain an envelope that contains 17 stick people. 2. Organize the Stick People according to patterns you see in their features including:
number of fingers, arms, hair, face expression etc. 3. The table you organize should show patterns in both horizontal rows and vertical
columns. 4. You will recognize that one stick person is missing. 5. Have your instructor OK the arrangement of your stick people.
Answer the following questions:
1. Mendeleev left gaps in the periodic table he created assuming that some elements had not yet been discovered. He made predictions about the properties of those elements. Use your table to make a drawing predicting the traits (properties) of the missing stick person.
2. Identify what features represent the following properties of the elements.
Property Periodic Stick Person feature Number of protons / electrons Number of Valence electrons Energy level 1 Energy level 2 Energy level 3 Noble gas Halogen Alkali metals Alkaline Earth metal Face expression Two up pointing triangles on shirt 3 dots on shirt Small polka dots on shirt Body size (thin / fat)
