The table is the arrangement of elements in increasing order of their atomic numbers. The modern periodic table is the present form of the periodic table. And it consists of 18 vertical columns and 7 horizontal rows.<\/p>\n\n\n\n<p>Q6<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Who found the first element of Periodic table?<\/h3>\n\n\n\n<p>In 1669, phosphorus was the first element to be chemically discovered by Hennig Brandt .<\/p>\n\n\n\n<p>Q7<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What are the 4 trends of the periodic table?<\/h3>\n\n\n\n<p>There are four main periodic trends, electronegativity, atomic size, ionization energy, and electron affinity.<\/p>\n\n\n\n<p>Q8<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How was the atomic number discovered?<\/h3>\n\n\n\n<p>Henry Moseley made the discovery of the atomic number in 1913 while analysing X-ray spectra. He discovered that when we increase the atomic number by one, certain lines in the x-ray spectra of atoms move by the same amount each time.<\/p>\n\n\n\n<p>Q9<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How many metals and non-metals are there in 118 elements?<\/h3>\n\n\n\n<p>There are 118 different elements in the current periodic table. There are 18 non-metals. There are 7 metalloids and 93 different types of metal.<\/p>\n\n\n\n<p>Q10<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What are the 4 blocks on the periodic table?<\/h3>\n\n\n\n<p>The valence electron orbitals of the elements in the periodic table are used to group them into blocks. The four blocks are s-block, p-block, d-block, and f-block.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Q1 How many elements are there in periodic table? 118 Elements are present in the Periodic Table.
