“碳”是宇宙大爆炸后,恒星核聚变反应所造就的一个神奇的非金属元素,熔点高达3550。C、沸点4800。C。它无处不在,没有它,地球上就没有生命和人类,也就没有动植物和有机界。真正碳元素有何特异之处?碳的单质元素有哪些?它的神奇之处你知道多少?火与炭一百万年前,“古猿”学会了用火取暖和防止野兽侵扰,并开始了烧制猎物,熟食大大提高了猿人的健康和智力。50万年前,中国猿人“北京人”在周口店猿人洞遗址遗留下大量的黑色灰烬,它就是人类最早熟知的含碳元素的木炭灰烬。熊熊燃烧的木材和草茎给人类带来温暖和光明,其中“碳”元素功不可没。
“Carbon ” is a magical non-metallic element created by the nuclear fusion reaction of the star after the Big Bang, with a melting point of up to 3550. C, boiling point 4800. C. It is everywhere, without it, there is no life and human beings on earth, there is no animal, plant and organic community. What are the specific carbon elements? What are the elements of carbon?
