Each element is defined by the number of protons found in each of its atoms. No matter how many electrons or neutrons an atom has, the element is defined by its number of protons. In fact, it's actually possible to have an atom consisting of only a proton (ionized hydrogen). The peri...

Atomic Structure Protons, Neutrons, and Electrons Section 4.3 Distinguishing Among Atoms Just as apples come in different varieties, a chemical element can come in different “varieties” called isotopes. 4.3 Protons Protons- determine the identity of an atom –Elements are different because they each...
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?
【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 ...
A neutral atom of iron has a mass number of 108 and an atomic number of 47. How many protons, electrons and neutrons are in this atom? How many protons and neutrons are in an atom with an atomic number of 35 and a mass number of 81?
Protons are tiny subatomic particles that, along with neutrons, form the nucleus of an atom. The heavier the atom, the more protons (and neutrons) it contains. Hydrogen, which is the lightest element, has a nucleus made from a single proton. The heaviest element in the Periodic Table, ...
