WebThe first ionisation energy (IE) trend across Period 3 is given in the sketch below. There are 3 observations: 1. General increase in first IE. 2. Slight decrease in IE from Mg to Al (first anomaly) 3. Slight decrease in IE from P to S (second anomaly) 1. WebSince the elements are in period 3, this means that all of them have an outer electron in energy level 3. However, the trend has two anomalies. The first is between Mg and Al, because the outer electron of Mg is in the orbital 3s, whereas that of Al is in 3p. The 3p electron has more energy than the 3s electron, so the ionization energy of Al ...
