alkali metals are the most reactive family
they are located in column 1 on the periodic table
Ground based reflecting telescopes uses the radio wave part of the electromagnetic spectrum to view objects.
<h3>What is a Telescope?</h3>
This is an optical instrument which makes things or objects which are far to look nearer.
Ground based reflecting telescopes are used in outer space and blocks gamma , light waves etc but uses the radio waves.

<span>The solubilties of most ionic solids increase as the temperature increases.
Dissolving of a solid in water is, in most cases, an endothermic
reaction. In dissolving, as in melting, a solid becomes a liquid. It
takes more energy to be a liquid than to be a solid at the same
temperature. When the solution becomes saturated at any temperature, a
dynamic equilibrium is established between the dissolved and undissolved
solid. When heat is added that results in a higher temperature, the
extra heat favors the endothermic reaction, and more solid dissolves
rather than crystallizes until new equilibrium system is established
again. Hence, at a higher temperature, more solid is dissolved in
water. This increases the solid's solubility.
Hope this helps mate =)

Answer: Boiling and Evaporation: Evaporation is the change of a substance from a liquid to a gas. Boiling is the change of a liquid to a vapor, or gas, throughout the liquid.

They're malleable and have high melting and boiling points
