Disk stars (yellow) population components: Correct Answer-- youngest stars - the Sun - high-mass stars - stars that all orbit in nearly the same plane Halo stars (green) population components: Correct Answer-- oldest stars - globular clusters - stars whose orbits can be inclined at any angle - stars with the smallest abundance of heavy elements In which of the basic regions of the Galaxy is the Sun located? Correct Answer-- galactic disk Which statement best describes the distribu...

Why do only the outer electrons leave their orbit shells? Answer Only outer electrons leave their orbit shells because electrons farthest from the nucleus are more easily freed from their orbits due to a weaker electrostatic force. What is required to have a balanced (or stable) atom? Answer The number of electrons must equal the number of protons in order to have a balanced atom. List the capacity of each of the first four orbital shells of an atom. Answer Shell: #1 = 2 electrons; #2 = 8 ...
