Why is liquid nitrogen used to fast freeze food instead of liquid oxygen? There are two reasons. First, liquid nitrogen is colder than liquid oxygen and thus more effective at flash freezing.
A similar effect occurs in aluminum, which has an electron configuration of 1s2 2s2 2p6 3s2 3p1. Even though oxygen is to the right of nitrogen in period 2, its first ionization energy is slightly lower than that of nitrogen. similar effect occurs in aluminum, which has an electron configuration of 1s2 2s2 2p6 3s2 3p1.
