∙ 14y agoThe phase of matter that has the least kinetic energy is the solid phase. You know that temperature is a measure of kinetic energy among molecules of a substance and solid is the phase of matter that occurs at the lowest temperature.
It is important to know the relative number of atoms of each element in a compound for the chemical composition.
Depends on the bonding it includes and the number of atoms of each element it includes.
You would also need to know the abundance of each of the isotopes, i.e., how much percent of each you will typically encounter.
The smallest subdivision that retains all of the properties of a molecular compound is a molecule, and the smallest subdivision that retains all of the properties of a ionic compound is a formula unit.
To know the quantity of matter present in the element or a thing
No. Water freezing into ice is a good example of a "phase change". Ice can melt back into water, so we know that the phase change is not permanent!

i dont know thats why am asking you for help
You need to know the atomic # or the masses of each isotope of the element.
Because each isotope of an element has a mass different from any other isotope of the same element, and the atomic mass of an element is an average, weighted by the proportion of each isotope, in the naturally occurring element.
It is important to know the relative number of atoms of each element in a compound for the chemical composition.
yeah i know .... its ..... the importance of each element is very important

i don't know go ask a nerd i just like messing with you and your dumb questions its fun you should try it
Because they never know if they're kid would have an element or not. I hope I helped.
Dark energy is believed to make up about 73% of the mass of the Universe; dar matter about 23%; and normal matter - the kind we know most about - about 4%. In the case of normal matter, most of it is still in the form of hydrogen.
