A proton is a subatomic particle found in the nucleus of atoms that differs from the other subatomic particles (called neutrons) in the nucleus of most atoms because each proton has a positive charge of +1 (as opposed to neutrons, which have no charge).
if a proton has a relative mass of 1 unit and a relative charge of +1 unit .what is the接上relative mass and charge of :1.a neutron2.an electron? 答案 质子,中子,电子...有什么关系?化学知识忘没了.搞清它们关系了应该就能选出来了.相关推荐 1if a proton has a relative mass of 1 unit...
