Each atom of carbon has 6 protons and electrons. The element naturally exists as a mix of three isotopes. Most of this carbon has 6 neutrons (carbon-12), plus there are small amounts of carbon-13 and carbon-14. Carbon-12 and carbon-13 are stable. Carbon-14 is used forradioisotope dat...

【英语】Everything in the Universe is made of atoms.All atoms are made of subatomic particles called protons, neutrons, and electrons. Each atom has a nucleus in the middle with electrons orbiting around it. 【汉语大意】宇宙中的一切都是由...
6 The mysterious universe 203 What remains of a supernova is extremely dense; the pull of gravity becomes so great that even the protons and electrons in atoms are forced together. They combine to form neutrons, and the resulting solid core is known as a neutron star. If the remaining...
Each atom may be used once, more than once or not at all.Select one atom from the six shown which(i) has exactly seven protons,J...(ii) has exactly six neutrons,E...(iii) has more protons than neutrons,D(iv) has the electronic structure [2,5],J...(v) is an atom of...
题目难度:容易 考点分析:求neutrons,electrons和protons之间的关系 题目分析:hydroxide ion有9个protons,带负一价电,所以electrons数量比protons多一个,为10个,立马就把答案B给选出来了。O有8个neutrons,H没有neutron,所以neutrons的数量为8。正确答案:B
