I NEED HELP PLEASE, THANKS! :)

What do elements in a group on the periodic table have in common?

They have the same number of neutrons in the nucleus.
They have similar chemical properties.
They have the same atomic mass.
Their valence electrons have the same energy level.

Elements in the same group in a periodic table have similar chemical properties.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).

the cold front replaces the warmer air at the ground level changing the wind to be breezy and denser.there is also an immediate drop in the temperature.
