Glossary term: 中子

Description: 中子是一種不帶電荷的亞原子粒子。我們周圍的所有物質都是由原子構成的,所有原子都具有相同的基本結構:一個由質子和中子組成的微小而緻密的原子核,幾乎承載了原子的全部質量,周圍環繞著電子。質子數就是原子核的 "原子序數",每個具有特定原子序數的原子對應於一種特定的化學元素,而中子數則決定了原子核代表的元素的同位素。

當一顆質量約為太陽 8 倍或更大的恆星接近生命終點時,其內核會坍縮,引發超新星爆炸,在爆炸過程中,內核中原子核的大部分質子會俘獲電子,轉化為中子,產生一顆中子星,如果內爆內核中剩餘的質量超過約 3 個太陽質量,則會產生一個黑洞。
