全部Atom related practice Atom is the basic unit of matter. It consists of proton, neutron, and electron. Protons and neutrons have about the same mass. The protons are positively charged particles (+) and neutrons carry no charge. The electron is a negatively charged particle (-) with 1/...
An ion has an unequal number of protons and electrons. If the charge is positive, there are more protons than electrons. If the charge is negative, electrons are in excess. You can find the number of neutrons if you know the isotope of the atom. Simply subtract the number of protons (t...
【题目】翻译一下可以吗1.An atom is made up of positive charges (protons),neutral charges (neutrons)and negative charges (electrons).T he protons and neutrons are found within the nucleus ofan atom,while we learnt in P08 Curious glowthat the electrons are found in different energy levels ...
atom呢? 答案 就是单数复数啦...比如说proton就是一个质子,protons就是多个质子……氢就是one proton……在这几个词中,nucleus比较特殊.nucleus是单数,nuclei是复数【参见半径单数=radius复数=radii】相关推荐 1英文词汇:molecules,nucleus,protons,neutrons,electrons一定要加S么,为什么.还是一般情况?atom呢?
Atoms are the basic building blocks of matter. Atom consists of three sub-atomic particles; they are protons, electrons and neutrons. Electron is a negatively charged particle, proton is a positively charged particle and neutron is a particle that has no charge.Thestrong nuclear forcebetween proto...
The atom is widely considered the fundamental building block in nature and consists chiefly of electrons, neutrons and protons.
