四种"新”元素

The Four "New" Elements & How We Got Them–Speaking of Chemistry

你们好 我是Buzzkill博士 我并没有像其他人看起来那样
Hey everyone. Dr. Buzzkill here. I’m not as jazzed or pumped about the periodic table’s four new
对元素周期表的四种新元素感到精神亢奋看下去你就知道为什么了
elements as everyone else seems to be. Stick around to find out why, and why these
我们还会告诉你为什么在很长一段时间内 这四个元素可能会是最后一组新增元素
four maybe the last ones we see added to the table for quite a while.
原因在这里 其实这些新元素不是什么新闻了
Here’s the thing. These new elements are actually old news. Scientists created
科学家们很多年前就发现了113 115 117和118号元素
elements 113, 115, 117, and 118 years ago. They’ve even had placeholders on the
他们甚至在元素周期表占位符上有过临时名称 由于IUPAC
periodic table with temporary names. They’re making news now because IUPAC,
也就是国际纯粹与应用化学联合会 正式将它们添加到元素周期表
the International Union of Pure and Applied Chemistry, is officially adding
使它们成为了新的元素 你也许想知道为什么花了那么长的时间
them to the periodic table. You might be wondering what took them so long.
是的 元素周期表非同小可 所以IUPAC需要审查任何新版本
Well, the periodic table is a pretty big deal so IUPAC needs to vet any new
那是他们的特权 给你们点儿时间好好欣赏下
edition. That’s their prerogative. I’ll give you a second fully appreciate that
鲍比·布朗的那首歌 创建和验证元素所做的实验
sick Bobby Brown reference. The experiments performed to create and verify elements are
是艰难的在这个星球上只有几个实验室可以处理
tough. There are only a few labs on the planet they can handle them. In a typical
在一个典型的实验中 研究人员将一束原子如钙或锌
experiment, researchers fire a beam of atoms, like calcium or zinc, into target made from
发射到由不同原子制成的如铋或锫的目标中 如果一切顺利的话
a different type of atom, say bismuth or berkelium. If all goes well, these atoms
这些原子会融合产生全新的超重原子问题是这些实验中
fuse to create brand new super heavy atoms. The problem is these experiments
只能产生了极少数新元素的原子而且这些原子
yield only a few atoms of the new element and those atoms don’t stick
还不会存留太久
around for long.
我们说的时间是不到一毫秒它们很快就会衰变为较轻的元素
We’re talking seconds to less than a millisecond. They rapidly decay into lighter
因此研究人员不得不从那些较轻的元素之后工作
elements, so researchers have to work backward from those lighter elements to
以使每个人相信他们所开始的东西实际上是新元素
convince everyone that what they started with was, in fact, the new element.
然后他们需要做更多的实验来确认新元素的存在
They then need to do more experiments to confirm the creation of the new element
然后我猜 他们就开始看《第五元素》了
and then I presume, watch the
但这些都需要很长的时间到现在没有人能成功地制造出
Fifth Element. And this all takes a while. Right now, no one’s had any success creating an
比118号重的元素 所以我们可能少则等几年 多则等几十年
element heavier than 118, so it will probably be years if not decades before
才能看到新元素增加到元素周期表里
we see any more elements added to the periodic table. Listen to me. Getting all
瞧我这激动的样子可能我是有些兴奋
worked up. Maybe I am kind of jazzed.
这里有很多的未知例如 元素周期表的第七行
And there really is a lot to geek out about here. For example, the seventh row of the
现在已经满了而新元素的正式名称和缩写
periodic table is now officially full and it should only be a few months before
应该只需要几个月的时间
the new elements get their official names and abbreviations. The naming is up
命名是由那些元素的发现者和IUPAC的人来决定的
to the people who discovered the elements and IUPAC, but that shouldn’t stand
但那不应该妨碍一些老式的游说活动我们以及许多人认为
in the way of some good old-fashioned lobbying. We and many others think there
应该有更多以女性命名的元素
should be more elements named after women. They’re responsible for a lot of
她们负责很多重要的核化学 你知道的 一般科学
important nuclear chemistry and, you know, science in general. Right now, there are
现在只有两种元素以女性的名字命名 好吧 应该说是一个半
only two elements named after women. Well, more like one and a half because Marie has
因为元素锔是由玛丽和皮埃尔共同命名的所以我们想倾听你的建议
a share curium with Pierre. So we want to hear your suggestions. What would you name the
你会把新元素命名为什么 在下面的视频中分享你的想法
new elements? Share your ideas in the comments below and we’ll give our
我们将在下一个视频中给出我们最喜欢的说到那个
favorite shout-out in our next video. Oh hey. Speaking of that. Did you notice something
你注意到这个视频有什么不同吗因为我们已经正式加入了反应小组
different about this video? That’s because we’ve officially joined the
意味着什么呢有更棒的化学知识等着你
Reactions team. What does that mean? More awesome chemistry for you. We’ll be
我们将尝试新的话题 非常期待那么请一定
trying out some new projects and we’re totally psyched about them, so be sure to
