意料之中情理之外:~
Ba~rium is fifty-sixth and this is where~the table splits,
while Lanthanides(镧系元素) have just begun,
Lanthanum(镧) Cerium(铈) and Pro-se-o-dy-mi-u~m (镨Pr, 读普)
Neodium(钕,读女) next to Promethium(钷Pm, 叵po3) and
62th's
Samarium(钐), Europium(铕) Gadolinium(钆) and Terbium(特)(山有嘎特)
Dysprosium(镝) Holmium(钬) Erbium(铒) Thulium(丢Tm)(l不双写)(迪火耳丢)
Ytterbium(Yb镱) Luteti~um(镥) (意鲁)
Hafnium Tantalum Tungsten(钨W,读'tungsen, 拉丁文Wolfrom) we're on to
Rhe-ni-um(铼Re) Osmium and Iridium
Platinum Gold to make you rich till you grow old(白金黄金)
Mercury(汞Hg,拉丁文Hydrargyrum)to tell you when itzs really cold(水银温度计)
Thallium(l双写) and Lead(铅Pb, 拉丁文Plumbum)and Bismuth for your tummy(铋盐胃药)
Pollonium(l双写) and Astatine would not be yummy
Radon Franci-um will last a little time(衰变)
Radium and Actanides at eigh-ty-nine
This is the periodic table,
noble gas is stable
halogens and alkali react agressively
each period will see new outer shells where
electrons are to the right
Ac-ti-ni-um,Thorium,Protoactinium(镤Pa, 读葡)
U-ra-ni-um
