Alkali metals: lithium, sodium, potassium, rubidium, caesium, francium.
Highly active metals are the most easily oxidized because they react with oxygen easily.
non metals in general
The Alkali metals are the most reactive group of metals in the periodic table. Of these Francium is the most reactive metal of all.
Non-metals are located on the very right of the Periodic Table. Metals are on the left.
Noble gases: helium, neon, argon, krypton, xenon, radon, ununoctium.
Highly active metals are the most easily oxidized because they react with oxygen easily.
groups 3-12
There are 2 most general categories. These are metals and non-metals.
No, cobalt is not more easily oxidized than magnesium. Grab a seat and look at the periodic table as we chat and you'll see why. Cobalt is a transition metal. Some of them oxidize a little bit and some resist oxidation. But magnesium is an Alkaline Earth Metal from Group 2 of the table. Those elements always oxidize in air because they are so reactive. Not as reactive as the Alkali Metals, which are in Group 1, but more so than any of the transition metals like cobalt. You'll find a link to a periodic table below. It's a very good one, and each element is a link to the post on that element. Bookmark this bad boy. It will allow you to learn a lot, and it will save you some time, too.
their general properties is that they are all non metals
non metals in general
The metals and non-metals have been arranged according to their densities in the periodic table.
metalloids like titanium and gold, in the center of the periodic table (im only 13 and i knew that)
Metals are not oxidized by UV radiation.
Elements on the left side of the Periodic Table are "Alkali Metals". There is also one non-metal element. H(hydrogen)
Elements of the periodic table
The three main metals in a periodic table are transition metals, alkali metals, and alakaline earth metals.
