list of metals on the periodic table

One can easily differentiate between metals and non-metals based on their placement on the Periodic Table of the Elements. Metals occupy the groups on the left of the periodic table. Group IA consists of highly reactive ..

Trends in the Modern Periodic Table - The periodic trends of the following properties are studied here. Atomic size Metallic and Non-metallic character Ionization potential Electron affinity Electronegativi..

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 resembles both alkali metals (group I A) as well as halog..

Position of Elements in the Modern Periodic Table - Types of Elements On the basis of electronic configuration, the elements of the periodic table are classified into: Noble gases Normal elements Transition elements Inner-transition elements Alkali metal..

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 el..

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 resembles both alkali metals (group I A) as well as halogens (g..

In spite of the above advantages, Mendeleev's periodic table suffered defects as follows: The position of hydrogen was not correctly defined. It was placed in group I although it resembles both the group I elements - the alkali metals and the group VII elements-the ..

>The modern periodic table is also known as the long form of the periodic table or the extended form of the periodic table. In this table, the elements are arranged in the order of increasing atomic numbers in such away that elem..

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., cation..

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..
