I believe the correct answer from the choices listed above is the third option. The noble-gas notation for lead (Pb) would be [Xe]6s^2 4f^14 5d^10 6p^2. The standard electron configuration of lead is 1<span>s^2 </span>2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^6 6s^2 4f^<span>14 5</span>d^10 6p^2 simplifying will lead to the part having the same configuration as xenon to be written as [Xe].
Pete because 2.5 x 2.3 is faster
Answer:
A cation is a positively charged ion, with fewer electrons than protons, while an anion is negatively charged, with more electrons than protons. Because of their opposite electric charges, cations and anions attract each other and readily form ionic compounds.

Answer:
They differ by their atomic mass and have same proton number.
Explanation:
Isotopes are atoms of the same element with the same proton or atomic number but with different atomic masses.
