一、三组记忆法在记忆金属活动性顺序时，可分成如下三组：钾钙钠镁铝、锌铁锡铅氢、铜汞银铂金。既顺口又好记。二、三条规律金属活动性顺序主要反映以下三条规律：（1）在金属活动性顺序中，金属的位置越靠前，在水溶液中就越容易失去电子变成离子，它的活动性就越强。（2） The first and third groups of memory methods can be divided into the following three groups when the sequence of metal activity is remembered: Potassium, Calcium, Sodium, Magnesium, Aluminum, Zinc, Iron, Tin, Lead, Hydrogen, Copper, Mercury and Silver. It’s easy to remember and easy to remember. The sequence of activity of two or three regular metals mainly reflects the following three laws: (1) In the order of metal activity, the more forward the metal is located, the easier it is to lose electrons into ions in an aqueous solution, and the more active it is, the stronger its activity will be. . (2)
