- Hydrogen Number 1 of the periodic table, with one electron orbiting one proton, hydrogen is the most abundant element in the universe and probably the first that ever existed. 4.
氫 氫是元素週期表中的 1 號元素，一個電子繞著一個質子運行，是宇宙中最豐富的元素，也可能是有史以來最早存在的元素。4.
- This is when a neutron within the nucleus changes into a proton and an electron, which is then ejected from the nucleus.

- So the first thing that happens is the alkene extracts a proton from HBr.
是以，首先發生的是烯烴從 HBr 中提取一個質子。
- So the alkene is going to abstract a proton, and we're gonna get water.
烯會抽取一個質子，然後得到水。

- It's made up of protons and neutrons. Skip forward to the 1960s and 70s and we realized that protons and neutrons are not elementary particles themselves. Each proton and each neutron contain three quarks. And the way it works is a proton has electric charge plus one.
它是由質子和中子組成的。進入二十世紀六七十年代，我們意識到質子和中子本身並不是基本粒子。每個質子和每個中子都包含三個夸克。其工作原理是質子的電荷數加一
- And the kind of quark called the down quark, which has charge minus one-third. So if you sit down there at home and try to figure out how can I make a proton, how can I make a neutron, you'll quickly figure out. A proton has two up quarks and one down quark. A neutron has two down quarks and one up quark. And that's a pretty good picture right there, but it becomes complicated by the fact that particles change identities sometimes. This was again an exciting thing in the early 20th century, radioactive decays.
還有一種夸克叫下夸克，它的電荷量是負三分之一。所以，如果你坐在家裡，試著想一想，我怎樣才能製造出質子，怎樣才能製造出中子，你很快就會明白。質子有兩個上夸克和一個下夸克。中子有兩個下夸克和一個上夸克。這就是一幅很好的圖畫，但由於粒子有時會改變身份，這就變得複雜了。這在20世紀初又是一件令人興奮的事 放射性衰變
