The metals list which makes up the periodic table includes iron, lead, gold, aluminum, platinum, uranium, zinc, lithium, sodium, tin, silver, etc. The nonmetals list which makes up the periodic table includes hydrogen, helium, carbon, sulfur, nitrogen, oxygen, radon, neon, other halogens, and noble gases etc.
What is the number of metals nonmetals and metalloids in periodic table?
There are 110 elements known to us, out of which 92 are naturally occurring, while the rest have been prepared artificially. Elements are further classified into metals, non-metals, and metalloids….Metalloids.
| Metals | Non-metals | Metalloids |
|---|---|---|
| Mercury | Sulphur | Germanium |
| Zinc | Phosphorus |

How many metals are there in the first 20 elements?
So the metals and non-metals are as follows: Metals in the first twenty elements are Lithium, Beryllium, Sodium, magnesium, Aluminum, Potassium, and calcium. Now the non-metals in the first twenty elements are Hydrogen, Helium, Carbon, Nitrogen, Oxygen, Fluorine, Neon, Phosphorous, Sulphur, Chlorine, and Argon.
Is mercury a metal?
Elemental or metallic mercury is a shiny, silver-white metal, historically referred to as quicksilver, and is liquid at room temperature. It is used in older thermometers, fluorescent light bulbs and some electrical switches.
How many total metalloids are there?
six metalloids
In the modern periodic table there are six metalloids which are boron , silicon , germanium , arsenic , antimony and tellurium . Metalloids usually look like metals but they behave largely like non metals.
How many metals are present in second periodic table?
Period 2 only has two metals (lithium and beryllium) of eight elements, less than for any subsequent period both by number and by proportion. It also has the most number of nonmetals, namely five, among all periods.
Are there 22 non metals?
In modern periodic table there are 22 non-metals in which there are 11 gases, 1 liquid and 10 solid. Bromine occurs in the state of liquid and hydrogen, nitrogen, oxygen, chlorine etc are found in gaseous forms. But carbon, sulphur, phosphorous, iodine etc solid non-metals.
How many metalloids are there in total?
There are just six metalloids. In addition to silicon, they include boron, germanium, arsenic, antimony, and tellurium. Metalloids fall between metals and nonmetals in the periodic table.

What is the percentage of metals in the periodic table?
What percentage of the periodic table of elements is metals? About 80 percent of the elements are metals (shiny elements that conduct heat and electricity well), and 15 percent of the elements are nonmetals (poor conductors of heat and electricity).
How many groups on the periodic table are metals?
According to modern periodic table there are 18 groups from up to down or columns. All groups are named after there first elements. First two groups named as alkali metals and alkaline earth metals respectively. Group 15 to 18 named as pnictogens, chalcogens ,halogens and noble gases respectively by IUPAC .
