一、分3组巧记忆在记忆金属活动性顺序时,可将其分成如下3组进行记忆:钾钙钠镁铝、锌铁锡铅氢、铜汞银铂金.用这种方法记忆既顺口又容易记住.二、3条规律金属活动性顺序主要反映以下3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.排在氢前面的金 First, the sub-3 clever memory In the memory of the activity of the metal sequence, it can be divided into the following three groups for memory: potassium calcium sodium magnesium aluminum zinc-lead-lead hydrogen copper silver mercury platinum with this method to remember Easy to remember. Two, three rules The sequence of metal activity mainly reflects the following three rules: 1 in the metal activity sequence, the metal the more front position, the more easily in the aqueous solution to lose electrons into ions, its The more active .2 gold in front of hydrogen
