Where are most metals on the periodic table?
On the periodic table, there is a group of elements called the metalloids, which are:
There is a distinct pattern that these metalloids make out on the table, and that is the shape of a staircase, starting from Boron and leading to the bottom (the reason Astatine and Tennessine are not metalloids is because they are halogens).
In summary, everything to the right of the metalloids are nonmetals, while elements to the left are either transition metals or metals.
Side note: Hydrogen is an exception of a nonmetal placed to the left of the periodic table- Hydrogen is here due to reasons regarding electron configuration, but I'm assuming that discussion is for another time.
