Without looking at the periodic table, identify the group, period, and block in which the element that has the electron configuration [Kr]5s 1 is located.2. a. Without looking at the periodic table, write the group configuration for Group 2 elementsb. Without looking a the periodic table, write the complete electron configuration for the Group 2 elements in the fourth period. Niels Bohr proposed, in 1913, what is now called the Bohr model of the atom.
