Solid.
Iodide is an ion formed from the element iodine, so it is not a compound.
Platinum is the transition element that is most commonly used in expensive jewelry due to its lustrous appearance, durability, and resistance to tarnishing.
Gold is the most commonly used element in making expensive jewelry due to its rarity, durability, and timeless appeal. It is prized for its luster and aesthetic qualities, making it a popular choice for luxury items.
Potassium ions (K+) are found in high concentration inside the neuron compared to outside. This concentration gradient is maintained by the sodium-potassium pump.
Meteorological balloons are made from natural latex rubber, mostly in Japan.
Mostly group 1 metals like sodium or potassium
Iodide is an ion formed from the element iodine, so it is not a compound.
The most basic element we have discovered is hydrogen. If you are refering to matter. If not it is mostly photons.
If you mean element-wise, living organisms contain mostly carbon, oxygen, hydrogen.

It is not. CO2 is more common on earth than O2 aswell as Hydrogen. In space its even less common.
Potassium sulfate does not help you breathe. It is used mostly as a fertilizer, not as a medicine.
Gas. The air is all around you. It is mostly seen in Solid, because look around you and you see almost only solid. It is commonly seen in liquid though also!
rocks- mostly metamorphic
Carbon mostly.
Granite is an example of an igneous rock that cooled slowly underground and contains mostly quartz and potassium feldspar.
Hydrogen The universe is mostly made of it (and helium), and hydrogen is basically 3/4 of all matter. On earth, the most common element is oxygen, if you include all the oxygen compounds, followed by silicon, aluminium, and iron
