group 4 element
暫時記得呢個 [表情]
一開始intro
跟住講佢d 有咩element,Si 同C 有network structure, high mp bp
跟住講c 係一隻特別d ge gp element:
catenation
no lowlying vacant d - orbitals
有兩個唔同個state diamond or graphite(講埋有咩bond 同force)
small atomic size
加埋佢form gas state oxide
成組黎講就down the gp form +4 ,上面form +2 ,原因係inert pair effect?
仲有佢地acidic oxide,落水出H+
我如果宜家去寫,寫得出咁多咋....
仲有咩要補充?
