What percentage of the periodic table of elements are metals?
80 % of the periodic table consists of metals and 15 % non-metals and 5 % other elements.
total no of elements in periodic table is 112.Some of which are still unnamed. Elements on the periodic table is classifies into metals, non-metals, semiconductors, and elements that are radioactive. Elements are arranged in increasing order of their atomic number. In a periodic table on the left are the metals, on the right are all non-metals and in the middle are the transition metals.
How can the arrangement of elements in the periodic table be used to predict how they react with other elements to form compounds?
the elements on the left hand and in the center of the periodic table are metals,on the right hand side are non metals and the elements separating the metals and non metals are metalloids. hence the arrangement of elements in the periodic table be used to predict how they react with the other elements to form compound.
