WebAug 15, 2024 · There is a general upward trend across the period, but this trend is broken by decreases between magnesium and aluminum, and between phosphorus and sulfur. Explaining the pattern First ionization energy is dependent on four factors: the charge on the nucleus; the distance of the outer electron from the nucleus; WebState the trends in reactivity of the group 1 and group 7 elements and explain the reasons why. Elements react by gaining or losing electrons. Elements wants to reach the stable state of having 8 electrons in the outermost ring, so group 1 elements react by losing an electron, since they have only 1 electron in their outermost shell.
