Question

Name the elements according to the properties given.

1.Strangely but luckily, there are no “transition metals” or “rare earth elements” on
the alien planet 2-4-D. Add the correct Roman numerals to the group numbers.
2. The “noble gases” are Bombal (Bo), Wobble (Wo), Jeptum (J) and Logon (L).
- Bombal (Bo) is a noble gas but does not have 8 outer electrons.
- The outside energy level of Logon (L) is its second energy level.
- Of these inert gases, Wobble (Wo) has the greatest atomic mass.
3. The “alkali metals” are Xtalt (X), Byyou (By), Chow (Ch), and Quackzil (Q).
- Of these alkali metals, Chow (Ch) has the lowest atomic mass.
- Quackzil (Q) is in the same period as Wobble (Wo).
4. The “halogens” are Apstrom (A), Vulcania (V), and Kratt (Kt).
- Vulcania (V) is in the same period as Quackzil (Q) and Wobble (Wo).
5. The element called Doggone (D) has only 4 protons in its nucleus.
6. The “metalloids” are Ernst (E), Highho (Hi), Terriblum (T), and Sississ (Ss).
- Sississ (Ss) is the metalloid with the highest atomic mass.
- Ernst (E) is the metalloid with the lowest atomic mass.
- Highho (Hi) and Terriblum (T) are in Group 14.
- T has more protons than Hi.
- The element called Yazzer (Yz) is a metalloid by location but has properties
that suggest it is more like a light metal.
7. The most metallic element on the planet is called Xtalt (X).
One of the most chemically active nonmetals on the planet
is called Apstrom (A).
8. The lightest element on the planet is called Pfsst (Pf).
-The heaviest element on the planet is Elrado (El), and is highly radioactive.

9. The chemical makeup of the alien planet’s oceans seems to be about
the same as Earth’s oceans. (NOTE: Earthly salt is the compound NaCl)
- 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 Pfsst (Pf)
and one atom of Nuutye (Nu).
- The solid left behind after the distillation consists mainly of a crystal made
up of the elements Byyou (By) and Kratt (Kt).

10. Floxxit (Fx) is a black crystal and has 4 electrons in its outermost energy level.
- Both Rhaatrap (R) and Doadeer (Do) have atoms with 4 energy levels.
- But Rhaatrap is less metallic than Doadeer.
11. Magnificon (M), Goldy (G) and Sississ (Ss) are all members of Group 15.
- Goldy has fewer total electrons than Magnificon.
12. Urrp (Up), Oz (Oz) and Nuutye (Nu) all gain 2 electrons.
- Oz has a lower atomic number than Urrp.
13. The element Anatom (An) tends to lose 3 electrons.
- The elements Zapper (Z) and Pie (Pi) both lose 2 electrons.
- Pie loses them from its fifth energy level, while
Zapper loses them from its third.

Explanation / Answer

1. These are all noble gases and they have group no 18. The elements are

Bo (bombal)

Wo (wobble)

J (jeptum)

L (Logon)
