Which of the following has the largest second ionization energy?

a) S
b) Mg
c) Si
d) Na
e) P

is the correct answer a)?

1 answer

No, the correct answer is c) Si.
Ionization energy refers to the amount of energy required to remove an electron from an atom or ion. The second ionization energy is the energy required to remove a second electron from a singly charged ion.
Among the provided options, Si (silicon) has the largest second ionization energy.
Here is the order of the second ionization energies for the given elements:
a) S (sulfur)
b) Mg (magnesium)
c) Si (silicon)
d) Na (sodium)
e) P (phosphorus)
