Hydride ion (H-) is an anion which is formed when an hydrogen atom gains an extra electron. The electronic diagram of hydride ion is:
圖片參考：http://hk.geocities.com/hoocch2ch2cooh/diagrams/hydride_ion.jpg
Hydride ion is usually found in the ionic hydrides of reactive metals, e.g. KH, NaH and CaH2. These hydrides are strong bases, unstable, and would react with water to give hydrogen gas.
e.g. NaH(s) + H2O(l) → NaOH(aq) + H2(g)
Such metal hydrides are included in the part of inorganic chemistry in HKAL.

"H-" 是 "Hentai&;quot; 的縮寫, 日文意思是"變態"

樓上d人有病=.=? 人地問緊化學 唔係問你變態唔變態...
hydride ion既然少見 咁佢一定唔會穩定
所以其實佢係一個好唔穩定的化學品
佢一般會以 LiAlH4 出現於有機化學入面的還原劑
將organic acid轉做alkanal / alkanol

H-GAME全個我就知點解(成人遊戲), 但係個H-係點解我就唔係好清楚, 我THINK係high咁解, 玩到好high個種game 就叫h(high)-game........這是我個人的認為, 我錯的請說 以前好少咸 game的, 只有在機鋪的美女麻雀脫衣game, 同而家d機鋪見到的麻雀一樣係好多鍵的, 以前的按鍵係排到好似"H-"型咁的, 所以就沿用至今了.... 常玩咸game朋友

H-Game,這個"H-";呢，其實是由日本來的。因為在日本，色色的事物叫做...henijokodo。所以啦，只要看到有"H";字樣的遊戲，差不多就是這個意思。本站提供站長搜集的hgame遊戲，包含介紹、試玩、下載...等。
