more protons= stronger force
electrons closer to the nucleus
experience (feel)
- the greatest effective nuclear charge
- the least shielding (blocking)
Electrons are pulled toward the nucleus by
the effective nuclear charge force
Effective nuclear charge
electrons farther from the nucleus
experience (feel)
- the least effective nuclear charge
- the most shielding (blocking)
