Na+ 既electronic diagram 應該點畫?(show outermost shell electron)

空電子 i.e. {Na}+

You may refer to "3. Ionic Bonding - electron transfer"
in the website http://www.wpbschoolhouse.btinternet.co.uk/page04/4_72bond.htm.

Hope it helps.

其實畫唔畫都得，我老師話2種都俾分
不過話畫outermost electron，你冇electron係個shell度就唔算outermost shell啦^^
所以我會畫哂8粒electron

空電子, i draw 空電子 for cations in homework and exam, they score marks
