一、元素性质(1)金属性和非金属性既对立又统一任何元素都同时存在金属性和非金属性,只不过一般元素中二者不能同时显示出来。某种元素的金属性越强,它们的非金属性就弱。而金属性越弱,它们的非金属性则越强。金属性较强的的元素主要表现金属性,人们称这些元素为金属元素;非金属性较强的元素主要表现为非金属性,人们称之为非金属元素;有些元素金属性与非金属性强弱相差不大,两种性质均能表现,例如Al、Zn、Si等,但人们根
First, the nature of the elements (1) metallic and nonmetallic both opposites and unified Any element of both metallic and nonmetallic, but the common elements of the two can not be displayed at the same time. The more metallic an element is, the less metallic it is. The weaker metallic, their non-metallic is stronger. Metallic elements of the main performance of the metal, people call these elements of the metal elements; non-metallic elements are mainly non-metallic, which people call non-metallic elements; some elements of metallic and non-metallic Strong or weak little difference between the two properties can be manifested, such as Al, Zn, Si, but people root
