• Maybe not. It has no protons, so therefore, it has no electrons Because proton number equals electron number, which means if it has no protons 0 its atomic number is zero.

    也可能不会,这个元素没有质子,因此,也没有电子,因为质子数等于电子数,意味着没有质子,的原子序数为。

  • This should make sense because if something has a low ionization energy, that means it's not very electronegative, which means it's going to be a lot happier giving up electron density, which is essentially what you're doing -- when you're forming covalent bonds is you're sharing some of your electron density.

    这应该是合理的,因为如果某物的电离能很低,这也就意味着的电负性也不高,那么就会更愿意,放弃一定的电子密度,而本质上这正是你在,形成共价键时所需要做的,分享你的一些电子密度。

  • God bless. Oh, sorry, that wasn't a sneeze, it was a two? How many swaps do I do in bubble sort? A lot. Right. Potentially a lot because I'm constantly doing that, that says I'm running that inner loop a whole bunch of times.

    上帝保佑,哦,抱歉,我没说清楚,这是两个问题,在冒泡排序中要做多少次排序?许多,正确的,可能要做很多次,因为在持续的干,这就意味着要做很多次内部循环。

  • So since it's a component of the angular momentum, that means that it's never going to be able to go higher than l is, so it makes sense that, for example, it could start at and then l go all the way up to l.

    因为是,角动量的分量,这意味着不会,比l大,这是很容易理解的,比如说,可以从零开始,一直到。
