Hey Buddy here's ur answer
An element is a substance that is made entirely from one type of atom.
For example, the element hydrogen is made from atoms containing a single proton and a single electron.
Currently, scientists know of 118 different elements. Some, like gold, silver, copper and carbon, have been known for thousands of years
These three groups are:
- metals
- nonmetals
- inert gases.
- First, the metals. They are found in the left, center and lower parts of the periodic table (red area). The metals are good at losing electrons, but they are poor at gaining electrons. The net effect is that the metals tend to lose electrons.
- Second, the nonmetals. They are found on the top and right side of the periodic table (blue area). They include hydrogen. The nonmetals are poor at losing electrons, but they are good at gaining electrons. They gain electrons better than they lose them. So the nonmetals can be characterized by their ability to gain electrons.
- Third, the inert gases, or the noble gases, as they are sometimes called, are found in the far right column of the periodic table (white area). Sometimes these are included with the nonmetals because they are not metals. However their behavior and properties are different enough from the other nonmetals that we will consider them as a separate classification. They are poor at both losing and gaining electrons. Therefore, for the most part, they neither gain nor lose electrons.
- We can also consider a fourth classification, the metalloids (marked with *). The transition from metallic properties and behavior to nonmetallic properties and behavior is not a simple matter of stepping over a line that can be drawn on the periodic table.
