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..

1.Chlorine is placed second after fluorine in group VIIA. 2. Other members of this group are fluorine, bromine, iodine and astatine (the last member is radioactive). 3. Members of this group are called 'halogens' meaning salt producers. 4. Atoms of halogens have seven electro..

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 metals called the alkali metals, w..

Introduction - All elements in the periodic table have been classified as metals and non-metals. The non-metals are placed on the right hand side of the 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 metals Halogen..

. They are called Lanthanides. The 7 t h period consists of elements that have atomic numbers 90 to 105. They are called Actinides. Both of them are called inner transition elements. 12. The 7 t h period is an incomplete period as it has only 23 ele..
