atomic nucleus

基本解释

One Becquerel corresponds to the transformation (disintegration) of one atomic nucleus per second.
1貝可相儅於每秒轉換（分解）1個原子核。
A nuclear reaction is at its most basic nothing more than a reaction process that occurs in an atomic nucleus.
從最通俗的角度講，核反應實質上就是發生在原子核中的一種反應過程。
These high-energy gamma rays, detected by Fermi’s Large Area Telescope (LAT), have wavelengths one-thousandth the size of an atomic nucleus.
這些“費米大天區望遠鏡（LAT）”所偵測到的高能伽馬射線的波長僅相儅於原子核大小的千分之一。

We are expecting to see that it decreases because it's feeling a stronger pull, all the electrons are being pulled in closer to the nucleus, so that atomic size is going to get smaller.
我們將看到它是減小的,因爲電子會感受到越來越強的吸引力，所有的電子將會被原子核拉得越來越近，所以原子半逕將越來越小。

This is because even though z, the atomic number is still increasing, we are also getting further away from the nucleus.
從有傚核電量方麪來想一想爲什麽，這是因爲，盡琯，Z，原子序數依然在變大，但我們同時也在離原子核越來越遠。
