Which of the following reactions represents an electron gain energy that would be positive (i.e. endothermic).
S(g) → S+(g) + e-
Cl(g) → Cl+(g) + e-
Kr(g) + e- → Kr-(g)
S(g) + e- → S-(g)
Kr(g) → Kr+(g)+ e-
Cl(g) + e- →Cl-(g)
Of the five elements Sn, Si, Sb, O, Te, which has the most endothermic reaction? (E represents an atom.) What name is given to the energy for the reaction? E(g) ⟶ E+(g) + e−
In the hydrogen atom, the electron is in its lowest energy state, n=1. The maximum electron energy that a hydrogen atom can have is 0 kJ/mole, at which point the electron would essentially be removed from the atom and it would become a H+ ion. How much energy does it take to ionize one hydrogen atom in kilojoules per mole and in Joules per atom? (Hint: calculate ΔE where εfinal is zero and εinitial is –1312.04 kJ/mol.)
