If you didn't have group II then you couldn't have group III!
Your question is a little broad - if you can name all the compounds group II elements form, I'll be happy to supply information.
However, seeing as you know so little and thus ask such an unanswerable question, start here:
Look at the wiki pages for the group II elements
Beryllium
Magnesium
Calcium
Strontium
Barium
Radium

keep in mind periodic factors like this:- Periodic table factors music study Chemistry and the Periodic table factors utilising music, and the elements music. The technology study explains why you should use music for gaining comprehend-how of. "the elements" music by technique of Tom Lehrer initiate: There’s antimony, arsenic, aluminum, selenium, And hydrogen and oxygen and nitrogen and rhenium And nickel, neodymium, neptunium, germanium, And iron, americium, ruthenium, uranium, Europium, zirconium, lutetium, vanadium And lanthanum and osmium and astatine and radium And gold, protactinium and indium and gallium And iodine and thorium and thulium and thallium. There’s yttrium, ytterbium, actinium, rubidium And boron, gadolinium, niobium, iridium And strontium and silicon and silver and samarium, And bismuth, bromine, lithium, beryllium and barium. There’s holmium and helium and hafnium and erbium And phosphorous and francium and fluorine and terbium And manganese and mercury, molybdinum, magnesium, Dysprosium and scandium and cerium and cesium And lead, praseodymium, and platinum, plutonium, Palladium, promethium, potassium, polonium, Tantalum, technetium, titanium, tellurium, And cadmium and calcium and chromium and curium. There’s sulfur, californium and fermium, berkelium and also mendelevium, einsteinium and nobelium And argon, krypton, neon, radon, xenon, zinc and rhodium And chlorine, carbon, cobalt, copper, Tungsten, tin and sodium. those are the in basic terms ones of which the information has come to Harvard, And there might want to be many others yet they haven’t been found. You keep in mind contained in the way of above music. all the suitable.

It's best to tackle them separately.
- Be isn't vaery important and all its compounds are toxic, so it's rarely used
- Mg is a metal that forms very light, durable alloys used i.e. in electronics (as the chassis elements) and anywhere else where weight matters, i.e. top-notch racing equipment. It's also a part of chlorophyll and a catalyst in many biiochemical processes.
- Ca is a major constituent of our bones (in the form of calcium phosphate). Its compounds are widely used in construction industry - i.e. Ca(OH)2 is used to make lime mortar, and CaCO3 is also known (depending on its form) as lime or marble.
- Sr is mainly used in pyrotechnics to produce red flames. It's also used in pottery and optics.
- Ba - barite (BaSO4) is used in petroleum industry to drill oil wells and as a contrast in X-rays of the digestive tract. Other compounds are used in pyrotechnics to produce green flames and in pigments.
There are more minor uses, but those are the most important.
