The atomic number of hydrogen is 1, so there is one electron in hydrogen.Complete Solution :- The periodic table is the arrangement of elements according to their increasing number of electrons and these electrons are filled in the orbits according to their increasing energies. There are various shells in the atoms which are denoted by K, L, M, N, etc, which represents the specific energy of the shell. The shell K represents 1, the shell L represents 2, the shell M represents 3, the shell N represents 4. Each shell has specific sub-shells which are s, p, d, f, etc.- According to the number of electrons in the atoms are arranged in the shells and the last shell of the atom is the valence shell and the electrons in that shell are valence electrons and these valence electrons are responsible for the bond formation. As the valence electron decides the block of the element, if the last electron enters in the s-subshell then the element is of s-block.- The atomic number of hydrogen is 1, so there is one electron in the hydrogen atom, therefore, its configuration will be $1{{s}^{1}}$. Only one electron is present and the last shell is 1s and there is 1 electron present in it, so the number of valence electrons is 1.Note: The K shell has one sub-shell (s), the L shell has two sub-shells (s, p), the M shell has three sub-shells (s, p, d), the N shell has four sub-shells (s, p, d, f). The valence electrons are the total number of electrons in the last shell combining all the sub-shell.Recently Updated PagesWhy are manures considered better than fertilizers class 11 biology CBSEFind the coordinates of the midpoint of the line segment class 11 maths CBSEDistinguish between static friction limiting friction class 11 physics CBSEThe Chairman of the constituent Assembly was A Jawaharlal class 11 social science CBSEThe first National Commission on Labour NCL submitted class 11 social science CBSENumber of all subshell of n + l 7 is A 4 B 5 C 6 D class 11 chemistry CBSEWhy are manures considered better than fertilizers class 11 biology CBSEFind the coordinates of the midpoint of the line segment class 11 maths CBSEDistinguish between static friction limiting friction class 11 physics CBSEThe Chairman of the constituent Assembly was A Jawaharlal class 11 social science CBSEThe first National Commission on Labour NCL submitted class 11 social science CBSENumber of all subshell of n + l 7 is A 4 B 5 C 6 D class 11 chemistry CBSE
