Most of the elements on the periodic table are metals, these metal elements form positive ions when reacting, while most non-metals don't form anything.
To our knowledge, all atoms want a full outer shell to be stable. If an element is found on the left, the number of electrons on its outmost shell is less than on the right side of the shell.
Metals become more reactive the lower you go on the periodic table because the further you go down, the more shells an element has. For example, Lead or Pb has six shells.
And since the positively charged nucleus is what keeps the electrons in their place, and the lead atom's electrons are far away from the nucleus, the lead atom can lose the electrons easily, this feature is what makes the bottom-most atoms more reactive than the ones at the top.
Metals are metallic bonding, which is special as their bonds are special to their element, and are very strong compared to other types of bonds, things that metals can do are as follows:
Copper has high melting points, is malleable can be bent or hammered into shape, and is a great conductor of heat and electricity. That's why we use copper in wires so often.
Another thing that metals can do is be sonorous which is the ability to make loud sounds when struck, this is why we use them in gongs, and commonly shiny metals are often used in jewellery.
Compared to non-metals which are very dull in colour and are often terrible at conducting electricity like wood, have low melting points and are brittle, but they have lower densities compared to metals making them lighter in weight.
Transistion metals are found the center of the periodic table, they.
