          • Alloys do not get corroded or get corroded to a very less extent.<\/li>\n
          • They are harder and str9ner than pure metals (Example: Gold is mixed with copper and it is harder than pure gold)<\/li>\n
          • They have less conductance than pure metals (Example: Copper is a good conductor of heat and electricity whereas brass and bronze are not good conductors)<\/li>\n
          • Some alloys have lower melting point than pure metals (Example: Solder is an alloy of lead and tin which has a lower melting point th\u00e0n each of the metals)<\/li>\n
          • When metal is alloyed with mercury, it is called amalgam.<\/li>\n<\/ul>\n

            Question 2.
            \nWrite the advantages of the Modern Periodic Table.
            \nAnswer:<\/p>\n

              \n
            • The table is based on a more fundamental property i.e., atomic number.<\/li>\n
            • It correlates the position of the element with its electronic configuration more clearly.<\/li>\n
            • The completion of each pe\u00e7iod is more logical. In a period, as the atomic number increases, the energy shells are gradually filled up until an inert gas configuration is reached.<\/li>\n
            • It is easy to remember and reproduce.<\/li>\n
            • Each group is an independent group and the idea of subgroups has been discarded.<\/li>\n
            • One position for all isotopes of an element is justified since the isotopes have the same atomic number.<\/li>\n
            • The position of the eighth group (in Mendeleev\u2019s table) is also justified in this table. All transition elements have been brought in the middle as the properties of transition elements are intermediate between the left portion and right portion elements of the periodic table.<\/li>\n
            • The table completely separates metals from nonmetals. The nonmetals are present in the upper right corners of the periodic table.<\/li>\n
            • The positions of certain elements which were earlier misfit (interchanged) in Mendeleev\u2019s periodic table are now justified because it is based on an atomic number of the elements.<\/li>\n
            • Justification has been offered for placing lanthanides and actinides at the bottom of the periodic table.<\/li>\n<\/ul>\n

              Question 3.
              \nExplain the position of hydrogen in the periodic table.
              \nAnswer:
              \nHydrogen is the lightest, smallest and first element of the periodic table. Its electronic configuration (1s1<\/sup>) is the simplest of all the elements. It occupies a unique position in the periodic table. It behaves like alkali metals as well as halogens in its properties. In the periodic table, it is placed at the top of the alkali metals.<\/p>\n

                \n
              • Hydrogen can lose its one electron to form a hydrogen ion (H+<\/sup>) like alkali metals.<\/li>\n
              • It can also gain one electron to form the hydride ion (H–<\/sup>) like halogens.<\/li>\n
              • Alkali metals are solids while hydrogen is a gas.
                \nHence the position of hydrogen in the modem periodic table is still under debate
                \nas the properties of hydrogen are unique.<\/li>\n<\/ul>\n

                Question 4.
                \nList the features of Mendeleev\u2019s Periodic Table.
                \nAnswer:
                \n1. It has eight vertical columns called \u2018groups\u2019 and seven horizontal rows called \u2018period\u2019.<\/p>\n

                2. Each group has two subgroups \u2018A\u2019 and \u2018B\u2019. All the elements appearing in a group were found to have similar properties.<\/p>\n

                3. For the first time,-elements were comprehensively classified in such a way that elements of similar properties were placed in the same group.<\/p>\n

                4. It was noticed that certain elements could not be placed in their proper groups in this manner. The reason for this was wrongly determined atomic masses, and consequently those wrong atomic masses were corrected. Eg: The atomic mass of beryllium was known to be 14. Mendeleev reassessed it as 9 and assigned beryllium a proper place;<\/p>\n

                5. Columns were left vacant for elements which were not known at that time and their properties also were predicted. This gave me the motivation to experiment in Chemistry. Eg: Mendeleev gave the names Eka Aluminium and Eka Silicon to those elements which were to be placed below aluminium and silicon respectively in the periodic table and predicted their properties. The discovery of Germanium later on, during his lifetime, proved him correct.<\/p>\n

                Properties of Germanium:<\/p>\n\n\n\n\n\n\n\n\n
