The Elements Of The Modern Periodic Table || Modern Periodic Table || Periodic Table

hello and welcome to this class in today's class we shall discuss and learn about the basic structure of modern periodic table here we focus on describing a periodic table basic parts of a periodic table and the features of the modern periodic table so now let's start periodic table is a combination of rows and columns in which elements are arranged systematically a vertical line or the column of the periodic table is called a group a horizontal line or the row of the periodic table is called a period there are total of 18 groups there are total of seven periods the group names are often written in Roman numerals as well different group number have their own significance in chemistry the group 18 or 8A is also called zero group the periodic table is also divided into different blocks they are named as s block P block d block an F block based on the nature and properties of the elements they are also named as alkaline metal alkaline earth metal transition metal and so on all the group one elements except first element are called alkaline metal all all the group two elements are called alkaline earth metal group three to group 12 element are called transition metal or transition element all the group 18 or zero group elements are called noble gases elements belonging from Group 13 to group 17 are known to have many names those elements marked by the light blue color on the table are known as non-metals the elements which are marked under orange color Boron silicon germanium arsenic antimony tarium and polonium are called metalloids those elements ments marked under purple color on the periodic table are also metals and often named as other metals the elements of group 17 or 7A are called hallogen f block consists of two series of elements consisting of 14 elements each these are called lanthanide series an actinide series some elements are radioactive in nature and they are named as radioactive elements the elements marked by yellow color on the periodic table here represents the radioactive elements I hope you simply understand the periodic table if you liked our video please love us by sharing this to others also please don't forget to subscribe and follow us on our YouTube channel and Facebook
