What is period and how many are there?
A period is a horizontal row in the periodic table of elements, where elements are arranged according to their increasing atomic number. There are seven periods in the periodic table, with each period representing the filling of a different electron shell. As you move from left to right within a period, elements display a gradual change in properties, from metals to non-metals. The first period consists of two elements, while subsequent periods contain more elements, with the seventh period being the largest.
