To determine how many times an atom is bigger than its nucleus, we can follow these steps:1. Understanding the Structure of an Atom: - An atom consists of a nucleus at its center, which contains protons and neutrons. -
At the centre of every atom is the atomic nucleus. The nucleus consists of particles calledprotonsand neutrons(collectively callednucleons) and contains almost all of the atom's mass, but is extremely tiny, with a diameter of about 10^-15 metres (0.000 000 000 000 001 m) or one femtomet...
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? 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:molecule...
The nucleus (plural nuclei) is the central part of theatom; it contains the protons and neutrons. Mass, Volume and Density Nearly all of the atom's mass is contained in the nucleus; the volume of the nucleus is tiny compared with the atom's total volume; thus the density of matter in...
