The chemistry of Uus is not known.
Flourine belongs to a class of elements called Halogens, which are similar in their chemical and physical properties. The other elements of this group are Chlorine, Bromine, Iodine, Astatine and Ununseptium. Astatine, however, is not considered to be a true halogen since it is radioactive in nature and Ununseptium is a synthetic element.
Ununseptium is an artificial chemical element.
Ununseptium is the temporary name given to the chemical element with the atomic number 117. It is a highly radioactive, synthetic element that was first synthesized in 2010 by Russian and American scientists. Its properties and uses are still under investigation due to its short half-life.
No. Chemical and physical properties are different.
Ununseptium, with the chemical symbol Uus, has the atomic number 117.
Physical and chemical properties change as the result of a chemical change, which produces new products with different physical and chemical properties than the reactants.
A chemical change is when the chemical properties of a substance changes and a physical change is when the chemical properties stay the same but the physical properties (shape, temperature etc...)
Copper has both chemical and physical properties. Chemical properties refer to how copper reacts with other substances, while physical properties refer to characteristics like its color, density, and conductivity.
Chemical property
The chemical properties of a substance change during a chemical reaction, meaning the substance undergoes a chemical change and forms new substances with different properties. The physical properties may also change, such as color, texture, or state of matter.
Matter has chemical properties (ex.: chemical reactivity) or physical properties (ex.: thermal conductivity).
