What is a description for helium?
Helium is a colorless, odorless, and tasteless gas that is the second lightest and second most abundant element in the universe. It is known for its low density and non-reactive properties, making it commonly used in applications like filling balloons or as a coolant in cryogenics.
What is the odor of nitrogeon?
Has no odor. Nitrogen is a gaseous chemical element, chemical symbol N, atomic number 7. Nitrogen is a colourless, odourless, tasteless gas, making up 78% of Earths atmosphere and is a constituent of all living matter. Kimber :)

What is the least common element in the universe?
Astatine is the rarest naturally-occurring element, with the total amount in Earth's crust estimated to be less than 1 oz (28 g) at any given time. This amounts to less than one teaspoon of the element. Guinness World Records has dubbed the element the rarest on Earth, stating: "Only around 0.9 oz (25 g) of the element astatine (At) occurring naturally". Isaac Asimov, in a 1957 essay on large numbers, scientific notation, and the size of the atom, wrote that in "all of North and South America to a depth of ten miles", the number of astatine atoms at any time is "only a trillion".
What is the heliums description?
