Elements
What elements are in the noble gases? Where are they located on the periodic table?
Helium, Neon, argon, Krypton, Xenon, radon, and oganesson, they are located in group 18 on the right side of the periodic table
What is Ionized energy, what level of energy are the noble gases?
Ionization energy is the minimum energy required to remove an electron from a gaseous atom or iron. Our group has the highest ionization energy, because of their stable, full valence electron shells.
What are noble gases used for?
The noble gases are used in many things that we use in our every day life, for example medicine, lighting, welding, lasers, and guided missiles
why are they called noble gases?
it reflects their “Unique” behavior, as they are unreactive to each other
Do the elements never react? If not why?
Are the densities of noble gases? relatively low, medium, or high?
The densities of the noble gases are relatively low, with values mostly less than 1 g/L.
Which element has the lowest boiling and melting point?
Helium
Are ALL noble gases completely stable?
No
What are the elements of the noble gases used for? Describe why its used for.
Because of their inertness, they are used in applications where a non-reactive environment is needed, such as in welding (argon) and in light bulbs (argon). Helium is used for balloons and blimps, and both helium and neon are used as refrigerants.
Noble gases have a very HIGH tendency to gain, lose, or share electrons with other atoms; True or False?
False
What 2 elements in the noble gases are used to create plasma?
Argon and Krypton
Does helium have a low boiling point?
Yes
What are 4 uses of the elements of the noble gases?
Can be used for things like lighting (neon, xenon, and krypton). Can be used for balloons/lifting gasses (helium). Can be used for cooling (helium). And inert atmosphere argon widely being used in arc welding to prevent hot metal reacting with oxygen and nitrogen in the air.
True or False; Xenon is used in high intensity lamps
True
What are the sources of your elements? (i.e. Are they found in nature? Where? If not, where were they made?) Answer for 3 elements.
-Helium source is found underground in natural gas deposits, often trapped near radioactive minerals, in stars, and the interstellar medium, found in nature. -Neon source is in trace amounts in the Earth’s atmosphere and crust, but it’s most abundant in the universe, especially in stars, it is also extracted from liquefied air. -Argon is found in the Earth’s atmosphere and present in smaller amounts in the earth’s crust and ocean water.
What is the electron configuration of Argon
1s^2 2s^2 2p^6 3s^2 3p^ 6
When were the noble gases discovered and by who?
Helium was discovered in August 18, 1868. A french astronomer named Jules Janssen during a solar eclipse, created in the sun from nuclear fusion, and on earth. It’s formed from the radioactive decay of heavy elements like uranium and thorium, as they release alpha particles and become helium atoms once they capture electrons.

-Krypton: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 (36 protons, 48 neutrons, and 36 electrons)
-Xenon: 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^6 (54 protons, 77 neutrons, 54 electrons)

Which prevents filament oxidation in light bulbs?
argon
Why do heavier noble gases like xenon and radon have a higher reactivity than helium or neon?
Their larger size means the outer electrons are further from the nucleus, are shielded by more inner electrons, and are therefore held less tightly
