推 roy047:題外話......是誰說自己感冒的= = 11/30 00:49
→ roy047:經驗式是empirical formula 11/30 00:50
→ LSer:感冒阿...還好有打針...下午就好很多了 11/30 01:00
(a) 恩...心照不宣
(b) di: 1+ 3+
pa: 0 2+
(c) +2
(d) because In has only two electronic state: +1 and +3, so it can only form
InCl or InCl3. These are all diamegnetic, so
when we consider InCl2, it is onlt the 經驗式 of the ionic solid. That
makes it to be a diamegnetic solid.
老話一句...我今天心情好好
風
