德国科学家弗里德里希·伟勒出生于 1 9世纪初 ,他求学期间 ,既攻医学也学化学 ,但他的主要精力却是放在无机化学方面。铝和铍这两个元素就是他发现的。在某一次化学实验中 ,伟勒把氰酸和氨放在一起 ,创造出一种由一个碳原子、一个氧原子、两个氮原子和四个氢原子组成的白色物 German scientist Friedrich Wehler was born in the early 19th century. During his study, he studied both medicine and chemistry, but his main focus was on inorganic chemistry. The two elements of aluminum and beryllium are what he found. In a chemical experiment, Wheeler put cyanic acid and ammonia together to create a white matter consisting of one carbon atom, one oxygen atom, two nitrogen atoms, and four hydrogen atoms
