fireworkium (fw): this element has 15 protons and 15 electrons in its neutral atom.

toothium (t): this is a nonmetal with an average atomic mass number close to 19.

floatium (fl): this is a gas that the aliens often use to fill balloons and blimps. it contains two protons in its nucleus.

breathium (bt): this element is a nonmetal and has one less proton than an atom of toothium and has an atomic mass close to 16 amu.

lightium (lg): this is a gas that does not react with other elements. it glows when it is heated in a lamp or vacuum tube. it contains one more proton in its nucleus than toothium.

rottoneggium (re): this is a nonmetal with one less electron than mustarium. it has a total of 16 electrons in its electron cloud.

i honestly don't understand

Basically they are asking you to find the element that is most closely associated with these clues.

1. Fireworkium: 15 protons and 15 electrons? No problem. We can see that the atomic number is 15, in which in real life, the element is Phosphorous. (Phosphorous is a common element in fireworks for an explosive personality and colors)

2. Toothium: A nonmetal with average mass number close to 19? We check the periodic table once more and find that Fluorine is our answer. (Notice that fluorine is in toothpaste, which is why they decided the name Toothier)

3. Breathium: Now honestly, I didn't even have to check the periodic table but just realize that we breath Oxygen. But if you want the straight answer, Oxygen is a nonmetal which has an atomic mass close to 16, and surprise, it has one less proton than Fluorine.

4.Lightium: Immediately we see that since this gas does not react with other elements, it is a noble gas. If it glows in a lamp or vacuum tube, we can also see it is of a light origin. If it has one more proton than Toothium (Fluorine) than we can immediately see that in the periodic table, our answer is Neon.

5. Rottoneggium: We can immediately guess sulfur. The straight way shows that it has 16 electrons, and the non-ion atom should also have 16 protons. Therefore, our answer is Sulfur.

6. I just realized I forgot Floatium: If it has 2 protons, we look in the periodic table and see that our answer is Helium.

Answer from: Quest

mechanics (greek is that area of science concerned with the behaviour of physical bodies when subjected to forces or displacements, and the subsequent effects of the bodies on their environment. the scientific discipline has its origins in ancient greece with the writings of aristotle and archimedes[1][2][3] (see history of classical mechanics and timeline of classical mechanics). during the early modern period, scientists such as galileo, kepler, and newton laid the foundation for what is now known as classical mechanics. it is a branch of classical physics that deals with particles that are either at rest or are moving with velocities significantly less than the speed of light. it can also be defined as a branch of science which deals with the motion of and forces on objects. the field is yet less widely understood in terms of quantum theory.
