What is thewhat is the approximate tilt of the earth's axis? approximate tilt of the earth's axis?

Earth's axis is tilted 23.5 degrees from the plane of its orbit around the sun.

But this tilt changes. During a cycle that averages about 40,000 years, the tilt of the axis varies between 22.1 and 24.5 degrees.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.

am i too late?
