curium    
n. 鋦



curium
n 1: a radioactive transuranic metallic element; produced by
bombarding plutonium with helium nuclei [synonym: {curium},
{Cm}, {atomic number 96}]

curium \curium\ n. [after Pierre and Marie Curie.]
a radioactive transuranic element of atomic number 96, having
an atomic weight of 247 for its most stable isotope
(half-life 1.6 x 10^{7} years). The chemical symbol is Cm.

Note: It was first prepared in 1944 by helium-ion bombardment
of plutonium in a cyclotron by Glenn Seaborg and
colleagues in California. It has never been detected in
nature, though minute quantities may exist in uranium
deposits as a consequence of the neutron flux there.

Syn: Cm, atomic number 96.

    The length of time it takes depends on the amount of time your student puts in per day With moderate other activities, 2 units per week is a reasonable amount We completed the course over the summer by making a calendar based on units around 3 scheduled weeks of "off" time The Zearn course is very independent and a bit of a chore I would recommend creating some study group interaction

    I think they mean a site to assist parents kids in getting through ST Math Thing is, this thing is apparently somewhat customizable The teacher can set the starting level, control how many attempts kids get before they have to start over, etc but a lot of them don't bother, making it even worse than it already is
