2014年10月14日
教学目的
1。使学生了解元素周期表的结构以及周期、族等概念。
、同主族元素性质的递变规律，能运用原子结构理论解释这些递变规律。
3。使学生了解原子结构、元素性质及元素在周期表中的位置三者间的关系，学会运用周期表。
教学内容
一、元素周期表的结构
（1)按原子序数递增的顺序从左到右排列，将电子层数相同的元素排成一个横行—-——周期。
（2）把最外层电子数相同的元素(个别例外）按电子层数递增的顺序从上到下排成纵行-——-族。
2。认识周期表的结构（7横行18纵列，7个周期、16个族）
(1）横：“三短、三长、一不全，镧系、锕系列下边"
（2)纵： “七主七副八与零，镧系锕系挤当中"
总结：①元素周期表有7行7周期，每一周期元素种类不一定相等。周期序数=原子核外电子层数
②元素周期表有18纵列、16个族、7个主族、7个副族、0族和Ⅷ族，主族元素最外层电子数=主族序数
③周期用纯数字表示，族用“Ⅰ-—Ⅶ”和“A”和“B”表示.“A”表示主族,“B”表示副族。例如：“N"所在位置为 第二周期ⅤA族或第2周期ⅤA族。

结论:随着原子序数的递增， 元素原子最外层电子排布发生周期性变化。
1、原子半径的递变规律:
结论：同一周期，随着原子序数的递增，元素原子半径逐渐减小，呈现周期性变化。
小专题：微粒半径大小的比较
（1）、原子半径大小的比较
同主族,从上到下，原子半径逐渐 增大 。同周期,从左到右，原子半径逐渐 减小（稀有气体除外）.
例如：Na 〉Mg 〉Al >Si
(2）、离子半径大小的比较
①具有相同电子层结构的离子半径大小的比较
电子层数相同，随着核电荷数的增加，原子核对核外电子的吸引能力 增大 ，半径 减小.(即核大径小）
例如：O2- > F— > Na+ > Mg2+ 〉 Al3+
②同主族离子半径大小的比较
元素周期表中从上到下,电子层数逐渐 增多，:F- < Cl— 〈 Br-
③同一元素的不同离子的半径大小比较
同种元素的各种微粒，核外电子数越多，半径 越大 ,高价阳离子半径 小于低价离子半径。
例如：Fe3+ 〈 Fe2+ < Fe H+ < H 〈 H-
2、化合价的周期性变化 标出1-18号元素的化合价，找出规律。
原子序数
最高正价或最低负价的变化
1～2
+1
3～10
+1 +5 -4 —1
11~18
+1 +7 —4 —1
结论：随着原子序数的递增,元素 化合价 也呈现周期性变化.
3、元素金属性非金属性周期性变化
结论：随着原子序数的递增，同周期元素金属性逐渐减弱，非金属性逐渐增
