What are elements with similar properties in the periodic table?

Back

Elements in the same group (column) of the periodic table have similar properties, such as Cl, Br, I, At.

What is refraction?

Back

Refraction is the bending of a wave as it passes from one medium to another, caused by a change in speed, such as light slowing down in water.
