For the default view of the periodic table, I imagined three-dimensional boxes that would contain the electron model of each element. The surface of each box would be translucent so that the user could get a rough idea of the element's volume. With gaze and air tap, the user could open...

2.1.2 单质 - Element 关于单质需要注意的是,”元素“与“单质”的英文都是“element”,因此需要根据语境来判断该英语单词的含义。有时为了去歧义,“单质”的英文也会被写成“free element”或“pure element”或“elementary substance”来与“元素”区分。 特定单质的英文名称同理,例如“氢元素”与“氢气/氢单质...

最后,元素周期表底部的镧系和锕系元素,以及元素钪和钇,我们把他们统称做稀土元素〔Rare Earth Element〕,他们的储量比较丰富,例如:铈元素的储量和铜的储量类似。那为什么叫他们稀土元素呢?因为他们几乎都存在于一种叫独居石矿〔monazite〕中,很难将他们分离,所以产量稀少。
