periodic table metals 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..

(with the exception of hydrogen) that are found to the right on the Periodic Table i.e., groups IIIA, IVA and VA. The non-metallic character of these elements increases from top to the bottom of the group. For example, in group VA the first and second members are non-h..

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 periodic trends of the following properties are studied here. Atomic size Metallic and Non-metallic character Ionization potential Electron affinity Electronegativit..

Covalent compounds are formed by the sharing of electrons by atoms of non-metallic elements between groups IVA and VIIA. The elements of these groups react with one another by sharing election pairs. Thus, the valency of an element in a covalent molecule is equal to the number of electron..

Covalent Compounds and Periodic Table - Covalent compounds are formed by the sharing of electrons by atoms of non-metallic elements between groups IVA and VIIA. The elements of these groups react with one another by sharing election pairs. Thus, the valency of an eleme..

Position of Hydrogen in the Periodic Table - Hydrogen is the first element of the periodic table. Its atomic number is 1, which indicates the presence of only one electron in the atom of hydrogen. This electron is present in its first shell. Hydrogen resemble..

Main Features of Modern Periodic Table - 1. The modern periodic table is divided into two main categories: (i) Vertical columns called Groups and (ii) Horizontal columns called Periods. 2. There are 18 vertical columns or groups. These are further s..

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. ..
