Question

does anyone know how to find the electron configuration of an element without using a periodic table?? group and period is already given

Answer 1

For that you have to use the Aufbau principle

For example, writing the electronic configuration of Fe(28)

I recommend that you memorize the aufbau principle. Once you learn it, you don’t need anything else except the atomic number of the element to write it’s electronic configuration.
