Step 1Let's solve this step by step:
Step 2: Understand Lead's Electronic Configuration
Lead (Pb) has the electron configuration $$1s^{2} 2s^{2} 2p^{6} 3s^{2} 3p^{6} 4s^{2} 3d^{10} 4p^{6} 5s^{2} 4d^{10} 5p^{6} 6s^{2} 4f^{14} 5d^{10} 6p^{2}
Final Answer
The lead ion has a + 2 charge so the net charge equals zero when combined with appropriate counter-ions.
