Oxygen Group Periodic Table

The group number is an identifier used to describe the column of the standard periodic table in which the element appears. Groups 1-2 termed s-block elements.

Periodic Table of Elements – Elements Database Periodic Table Our periodic table of chemical elements presents complete information on the chemical elements including the chemical element symbol, atomic number, atomic weight and description.

An up-to-date periodic table with detailed but easy to understand information

The modern periodic table, based on atomic number and electron configuration, was created primarily by a Russian chemist, Dmitri Ivanovich Mendeleev, and a German physicist, Julius Lothar Meyer, both working independently.

Elements as Building Blocks The periodic table is organized like a big grid. Each element is placed in a specific location because of its atomic structure. As with any grid, the periodic table has rows (left to right) and columns (up and down).

The chalcogens (/ ˈ k æ l k ə dʒ ɪ n z /) are the chemical elements in group 16 of the periodic table.This group is also known as the oxygen family.It consists of the elements oxygen (O), sulfur (S), selenium (Se), tellurium (Te), and the radioactive element polonium (Po).

At -183.0DegreeC oxygen is a beautiful pale blue liquid, but at room temperature it is a colorless gas. It’s only 21% of the atmosphere–the 21% we all need if we want to live more than a few minutes longer.

years Is the time it took to place Dalton’s set of Atomic weight values in the first periodic table. In today’s world of instant news and communication one might be shocked to know that it took a lot longer in the 1800’s to discuss ideas with colleagues.

The periodic table is a tabular arrangement of the chemical elements, ordered by their atomic number, electron configuration, and recurring chemical properties, whose adopted structure shows periodic trends.

The periodic table of the elements. The periodic table is an arrangment of the chemical elements ordered by atomic number so that periodic properties of the elements (chemical periodicity) are made clear.
