Why do the metallic elements typically have a lower ionization than the nonmetallic elements of the same row?
A. Metallic elements can only accept one or two valence electrons while nonmetallic elements can accept the excess electrons
B. The nonmetallic elements have a higher ionization because they are able to accept more photons

What does Bohr's atom model say about electrons?
What is electrons move in circular orbits around a nucleus-- electrons remain in orbits unless disturbed-- when an electron jumps from one orbit to another, energy is released or absorbed
