The halogens are quite chemically reactive and tend to pair up with alkali metals to produce various types of salt. The table salt in your kitchen, for example, is a marriage between the alkali ...
Elements of the periodic table that are gases are just called gases. There is a whole group of elements in the table that are gases, and they're the inert gases or noble gases .
The periodic table of elements can be divided into three element groups on the basis of their chemistry: metals, nonmetals and metalloids. Metals, in turn, are classified as alkali metals, alkali earth metals and transitional metals, which have much in common with the metalloids.
The six noble gases are found in group 18 of the periodic table. These elements were considered to be inert gases until the 1960's, because their oxidation number of 0 prevents the noble gases from forming compounds readily. All noble gases have the maximum number of electrons possible in their outer shell (2 for Helium, 8 for all others ...
From left to right in the periodic table, the nonmetals can be subdivided into the reactive nonmetals which, being nearest to the metalloids, show some incipient metallic character, and the monatomic noble gases, which are almost completely inert.
Every element can be transformed into a gas at a certain temperature. At 0°C the elements in their gaseous form are Hydrogen, Helium, Nitrogen, Oxygen, Fluorine, Neon, Chlorine, Argon, Krypton, Xenon, and Radon.We can use this Periodic Table of the Elements and find that at a given temperature the elements that are in red are in their gaseous stage.
Knowing which ones are or are not will help us to group them correctly. Before going over the complete list of metals, it is important that we define what is a metal. There are five different kinds of metals: Alkali Metals. Alkali Earths. Transition Metals. Lanthanides. Actinides. All metal elements are placed together in the periodic table.
Alternative periodic tables are tabulations of chemical elements differing significantly in their organization from the traditional depiction of the periodic system. Several have been devised, often purely for didactic reasons, as not all correlations between the chemical elements are effectively captured by the standard periodic table.. Alternative periodic tables are developed often to ...
The three types of elements found in the periodic table are the metals, which tend to donate electrons, the nonmetals, which tend to acquire electrons, and the noble gases which tend to remain as ...
On many periodic tables, a jagged black line (see figure below) along the right side of the table separates the metals from the nonmetals. The metals are to the left of the line (except for hydrogen, which is a nonmetal), the nonmetals are to the right of the line, and the elements immediately adjacent to the line are the metalloids.
