Solution: Which reaction below represents the second ionization of Sr?a. Sr(g) → Sr+(g) + e -b. Sr2+(g) + e - → Sr+(g)c. Sr+(g) + e - → Sr(g)d. Sr -(g) + e - → Sr2-(g)e. Sr+(g) → Sr2+(g) + e -

Solution: Which reaction below represents the second ionization of Sr?a. Sr(g) → Sr+(g) + e -b. Sr2+(g) + e - → Sr+(g)c. Sr+(g) + e - → Sr(g)d. Sr -(g) + e - → Sr2-(g)e. Sr+(g) → Sr2+(g) + e -

Problem

Which reaction below represents the second ionization of Sr?

a. Sr(g) → Sr+(g) + e -

b. Sr2+(g) + e - → Sr+(g)

c. Sr+(g) + e - → Sr(g)

d. Sr -(g) + e - → Sr2-(g)

e. Sr+(g) → Sr2+(g) + e -

Solution

Ionization energy (I. E.) is the energy required to remove an electron from a gaseous atom or ion.

First I.E. corresponds to removing thfirst valence electron from a neutral atom

 Second I.E. refers to removing a second electron

 Third I.E. refers to removing the third electron
