All substances will change state at specific temperatures, known as their melting and boiling points. Many substances can exist as solids, liquids or gases, which are all different states of matter.

A substance's melting point is the temperature at which it transitions from solid to liquid. This transition requires ...

For decades, our understanding of the three basic states of matter—solids, liquids ... only offers a practical tool for predicting melting points but also reveals a surprising universality ...

In the solid state it forms an fcc crystal with a melting point of -189.4 C and a boiling point of - 185.8 C. The electronic configuration of Argon is (Ne)(3s 2)(3p 6). Its atomic radius is 0.098 nm.

In the solid state it forms a tretragonal crystal with a melting point of -101 C and a boiling point of -34.7 C. The electronic configuration of Chlorine is (Ne)(3s 2)(3p 5). Its (-1) ionic radius is ...
