That will tell you where it has a stable configuration (eight electrons). Since the sixth ionization energy is the highest, we can conclude that this is where we reach a stable configuration.

WebThe graph shows how the first ionisation energy varies across period 3. First ionisation energy generally increases across period 3. However, the trend needs a more detailed consideration than the trend in group 2 . WebThe third ionisation energy shows a massive increase because it requires an electron to be removed from magnesium’s second energy level. \[Mg^{2+} (g) \rightarrow ... dhhs ottawa county

WebThere 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. General increase in first IE. The concept used to explain the general trend is involving effective nuclear charge. Across the period proton number increases hence nuclear ... cigna health customer service phone number
