求SAT2化学和物理的知识点总结
我复习化学用的巴郎,虽说很详细,但是太详细了也.感觉主次不清复习得比较无理头.
所以我想求助各位有没有总结好的知识点,这样复习起来比较有效率,我的时间不多了啊.
举个例子吧:
*Chemical periodicity:
·Atomic radii:when go from left to right,the radii decrease.
·Electronegativity:decrease down a group,increase across a period
·Ionization energy:.
*Bonding:
·ionic bonds:.
·covalent bonds:.
诸如此类的,
