The element being used here is [blank_start]neon[blank_end]. It belongs to Group [blank_start]0[blank_end], also known as the [blank_start]noble[blank_end] gases. These gases are [blank_start]not[blank_end] reactive.

Balance the following equation: [blank_start]2[blank_end]\(Li +\) [blank_start]2[blank_end] \(H_2O \rightarrow\) [blank_start]2[blank_end]\(LiOH + \)[blank_start]1[blank_end]\(H_2\)

Balance the following equation which shows the reaction between hydrogen and halides [blank_start]1[blank_end]\(H_2 +\) [blank_start]1[blank_end]\( Cl_2 \rightarrow\) [blank_start]2[blank_end]\(HCl\)

Balance the following equations which show the reaction of halogens with metals: [blank_start]1[blank_end]\(Cl_2 +\)[blank_start]1[blank_end]\(Mg\rightarrow\) [blank_start]1[blank_end]\(MgCl_2\) [blank_start]1[blank_end]\(F_2 +\) [blank_start]2[blank_end]\(Na \rightarrow\) [blank_start]2[blank_end]\(NaF\)
