Yes. There are only about 20 nonmetals and only 7 metalloids. The rest of the elements are metals.
What is element 120 on the periodic table?
There is no element 120. The highest atomic number according to the current periodic table is 118, of which only 3 atoms have been synthesized. There are only 92 naturally occurring elements. The rest have been, or will be synthesized in special laboratories.
Why are two of the row of the periodic table separated from the rest of the chart?
They are called the Lanthanide Series and the Actinide Series. If you look carefully, you will see the the atomic #s (the little # on the top of each element) on the two rows are in between the atomic numbers in the main periodic table. Also, some versions of the periodic table have arrows showing where they are supposed to go.The two rows actually belong in the main periodic table. The first row belongs between elements 57-71, and the second belongs between elements 89-103.They are separated because if they were put in the main table, it would make it too long.Hope this helped!Read more: Why_are_two_row_of_the_periodic_table_elements_separated_from_the_rest_of_the_chart
