\newpage  \section{EL8}  \subsection{Groups 1 and 2} \begin{itemize}  \item Elements become more metallic down a group  \item More readily form cations  \item More reactive down group  \end{itemize}  \\  \begin{itemize}  \item Elements are less metallic across a period from left to right  \item Group 1 elements are therefore more reactive than corresponding Group 2 elements  \end{itemize}  \subsection{Chemical Reactivity}  \begin{itemize}  \item Group 1 and 2 elements show patterns of reactivity down group  \item Similarities between reactions in a group  \item Due to similar electronic arrangements  \item Differences that show as trends  \item Due to increase in atom size  \end{itemize}  \subsubsection{First Ionisation Enthalpy}  If sufficient energy is given to an atom, an electron is lost and the atom is ionised to become a positive cation. The first ionisation enthalpy of an element is the energy needed to remove one electron from every atom in one mole of isolated gaseous atoms of the element.  \begin{equation*}  \end{equation*}
