People usually refer to a horizontal row on the periodic table as a period, which means that the outermost electrons of the elements on the horizontal rows of the periodic table are circulated from one to eight; the vertical columns of elements are called groups, which means that the elements in Periodic Table of elements period 1 Hydrogen (1) Beryllium (2) Scandium (3) There are only two elements in the first period: hydrogen and helium.

A period is a horizontal row of the periodic table. There are seven periods in the periodic table, with each one beginning at the far left. A new period begins when a new principal energy level begins filling with electrons. Period 1 has only two elements (hydrogen and helium), while periods 2 and 3 have 8 elements.

In terms of electronic structure of the atom, a period constitutes a series of elements whose atoms have the same number of electron shells i.e. principal quantum number (n). Each successive period in the periodic table is associated with the filling of the next higher principal energy level (n = 1, n = 2, n = 3, etc.)
