What is the format of the periodic table?

The periodic table is arranged by atomic weight and valence electrons. These variables allowed Mendeleev to place each element in a certain row (called a period) and column (called a group). The table comprises seven rows and 18 columns.

How many versions of the periodic table are there?

But within 100 years of the appearance of Mendeleev’s Periodic Table, it is thought that around 700 different versions were published, all taking many shapes and forms in different dimensions, from spirals, cylinders and rings, to fractals and pyramids.

Why is it called periodic?

Why is it called the Periodic Table? It is called “periodic” because elements are lined up in cycles or periods. From left to right elements are lined up in rows based on their atomic number (the number of protons in their nucleus).

What is the most unique element?

The rarest naturally occurring element is astatine (At). There are about 28 g of it in the Earth’s crust. Astatine got its name from the Greek word astatos, meaning unstable. Carbon (C) reacts with other elements to produce 10 million different compounds.

What are the 5 most important elements?

1. Note that most living matter consists primarily of the so-called bulk elements: oxygen, carbon, hydrogen, nitrogen, and sulfur—the building blocks of the compounds that constitute our organs and muscles. These five elements also constitute the bulk of our diet; tens of grams per day are required for humans.

What are the 2 main types of elements?

The elements can also be divided into two main groups, the metals and the non-metals. Metals are typically have a metallic sheen (shiny) are malleable (bendable) and conduct electricity. Nonmetals typically do not show these properties.

WHO classified elements first?

The earliest attempt to classify the elements was in 1789, when Antoine Lavoisier grouped the elements based on their properties into gases, non-metals, metals and earths.

What is the weakest element?

For the weakest element, I would probably go for helium – one of the noble gases. It is very light and unreactive.
