How does digging for fossil fuels affect the environment? how do they affect the environment?

Fossil fuels are not only the primary source of global warming pollution but it also threatens the stability of our climate,but also dangerous to our health as humans and also the environment.

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.
