Honestly idk if this is correct but. 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 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 simplifying will lead to the part having the same configuration as xenon to be written as [Xe].
PH of solution will be greater than seven (pH>7), that means that solution is basic (<span>pH above </span>7<span> is a base, the higher the number, the stronger is the base).
</span>pH (potential of hydrogenis) is a measure of the hydrogen ion (H⁺) concentration of a solution. <span>Solutions with a pH less than 7 are acidic.</span>
