Effective nuclear charge measures the attraction a valence electron feels to the nucleus of an atom. It is calculated by subtracting the​ (a)   from the​ (b)  

• number of core electrons
• total number of protons
• number of valence electrons
• total number of neutrons

Match the effective nuclear charge to the correct atom

• +8

• Mg

• +2

• P

• +3

• Ar

• +7

• Al

• +5

• Cl

Considering the metals: Na, Mg, and Al we note that ​ (a)   has the highest effective nuclear charge. During an experiment we note that Al is the least reactive of the three metals. We would predict​ (b)   to be the most reactive.

• Al
• Na
• Mg
