periodic table showing metals nonmetals and metalloids

Elements that behave like both metals and non-metals are called metalloids. Common metal, non-metals and metalloids Metals Non-metals Metalloids Gold Oxygen Silicon Silver Car..

Introduction - Earth is an abundant source of materials. The air we breathe, the water we drink, stones and rocks, almost everything that is around us, are all useful to man for some purpose or the other. Gaseous materials like Oxygen, Nitrogen and Carbon dioxide are found in the atmosphere. Common..

Position of Oxygen and Sulphur in the Periodic Table - 1. Oxygen is the first member of the group VIA and sulphur is the second member of the group VI..

One can easily differentiate between metals and non-metals based on their placement on the Periodic Table of the Elements. The metals are elements (with the exception of hydrogen) that are found to the left of a group of elements referred to a..

The tendency of an element to lose electrons and form positive ions (cations) is called electropositive or metallic character. For e.g., alkali metals are the most electropositive elements. "The tendency of an element to accept electrons to form an anion is called its non-m..

Periodic Table and Valency of Elements - a) Group IA, IIA and IIIA consists of metals of normal elements. They have 1, 2, or 3 valence electrons which they can easily donate to acquire the configuration of nearest noble gas. They become positively charged i.e., cations..

Modern Periodic Table-Long Form Periodic Table of Elements - Later, Henry Gywn-Jeffreys Moseley showed that the atomic number of an element is numerically equal to the number of electrons round the nucleus. The number of electrons in turn is equal t..

1. The position of hydrogen is still not settled since it shows properties of both alkali metals as well as halogens. 2. Lanthanides and actinides are not accommodated in the main body of the periodic table..

Defects of the Long form Periodic Table - 1. The position of hydrogen is still not settled since it shows properties of both alkali metals as well as halogens. 2. Lanthanides and actinides are not accommodated in the main body of the periodic t..
