With some time on my hands and a bit of my chemistry course in my mind, I decided I’d look for the atom which has the lowest Kelvin degree to turn into solid state. I found out that the helium is the atom which needs the lowest temperature to turn into a solid. It would need to be frozen to a temperature almost near the zero absolute, which is 0K. The helium "should" turn into a solid phase at 0.95K which is an extremely low temperature hard to achieve. Liquid
and
can transform into solid phases called "quantum crystal", with the aid of pressure of about 30 atmospheres.
