Using the periodic table, you can classify the elements in many ways. One useful way is by metals, nonmetals, and metalloids. (See also The Periodic Table: Families and Periods.) Most of the elements on the periodic table are classified as metals. Metals In the periodic table, you can see a stair-stepped line starting at Boron […]
The periodic table, also known as the periodic table of elements, is a tabular display of the chemical elements, which are arranged by atomic number, electron configuration, and recurring chemical properties.The structure of the table shows periodic trends.The seven rows of the table, called periods, generally have metals on the left and non-metals on the right.
Most of the elements needed for life are relatively common in the Earth's crust. Aluminium, the third most common element in the Earth's crust (after oxygen and silicon), serves no function in living cells, but is harmful in large amounts. Transferrins can bind aluminium. Periodic table

The most common elements on Earth are oxygen, silicone, aluminum and iron. Oxygen makes up about 46 percent of Earth by weight, while silicone makes up about 28 percent, and aluminum and iron make up approximately 8 and 5.5 percent, respectively. After the most abundant elements, most elements become much harder to find.
Most of the elements in the periodic table are classified as. Metalloids. The elements that touch the zigzag line are classified as. Nonmetals. The elements in the far upper right corner are classified as. Alkali Metals. Elements in the first group have one outer shell electron and are extremely reactive. They are called
Elements of the periodic table are grouped as metals, metalloids or semimetals, and nonmetals.The metalloids separate the metals and nonmetals on a periodic table. Also, many periodic tables have a stair-step line on the table identifying the element groups.
