解析 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】 分析总结。 比如说proton就是一个质子protons就是多个质子

Both protons and neutrons have a relatively large mass compared to electrons, which are much smaller and orbit around the nucleus in the electron cloud. Therefore, the mass of an atom is concentrated in the nucleus. Rate this question: 2 0 6. What are electrons? A. Positively charged ...
Atom Model4+ Periodic Table Luis Biehl Designed for iPad Free Screenshots iPad iPhone Description Periodic Table including 118 elements. Press the Element Symbol and display the simulation of the atom. Nucleus contains Protons and Neutrons, around the nucleus move the electrons. ...
So, you know you need 6 protons to make a model of carbon. To make a carbon atom, make 6 protons, 6 neutrons, and 6 electrons. Bundle the protons and neutrons together to make the nucleus and put the electrons outside the atom. Note that the model gets slightly more complicated when...
Making an atomic model together can help them translate this idea into something a little more concrete. Structure of an Atom Protons, Neutrons & Electrons…OH MY! Atoms are a combination of protons, neutrons and electrons. The nucleus of an atom appears like the protons and neutrons are ...
【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 ...

Key Takeaways: Model of the Atom An atom is a building block of matter that cannot be broken apart using any chemical means. Nuclear reactions can alter atoms. The three parts of the atom are protons (positively charged), neutrons (neutral charge), and electrons (negatively charged). ...
The protons and neutrons could be balls distinguished only by their color; the electrons are best represented in this scheme by far smaller balls.Atom Model Project Ideas Argon atom 3D model: From the table of elements, argon (Ar) has an atomic number of 18 and an atomic mass of 39.95. ...
