neon

neon  英 [ˈni:ɒn] 美 [ˈniɑn]

n. 霓虹灯;氖(10号元素,符号Ne) 

名词复数:neons 

If it could only ditch this electron, it could have the same electronic structure as neon. 如果它能失去这个电子,它就能和氖有一模一样的电子结构。
So if we want to write out what that would be, it would just be to say that f minus is isoelectronic with neon. 那么如果我们把它写出来,它应该就是负一价的氟离子与氖原子是等电子的。

  • Neon is a gas that’s often used to light up signs. Neon signs are made with tubes filled with the glowing gas. Neon also describes really bright colors that appear to glow, like a punk rocker’s neon orange Mohawk.

  • 3. The answer to that is definitely no -- if they had the same electron configuration, they would, in fact be neon. But we can think about different ions that have this electron configuration.

    答案是绝对没有-,如果它们具有相同的电子排布,那么它们,实际上,将都是氖,但是我们可以想一想,有没有其它离子具有这种电子排布呢?

  • neon (n.) 1898, coined by its discoverers, Sir William Ramsay and Morris W. Travers, from Greek neon, neuter of neos "new" (see new); so called because it was newly discovered. Neon sign is attested from 1927.
