The antonym of “atom” is ___. A. molecule B. particle C. compound D. element 相关知识点: 试题来源: 解析 C。“atom”意为“原子”,“compound”意为“化合物”,与“atom”相对。“molecule”分子;“particle”粒子;“element”元素,都不是“atom”的反义词。
A molecule is defined as the smallest unit of a compound that contains the chemical properties of the compound. Molecules are made up of groups of atoms. Describing thestructure of an atom, an atom is also sub-divided into smaller units. Proton, electrons, and neutrons are sub-particles of...
molecule - (physics and chemistry) the simplest structural unit of an element or compound free radical, radical - an atom or group of atoms with at least one unpaired electron; in the body it is usually an oxygen molecule that has lost an electron and will stabilize itself by stealing an ...
But as yet we have not considered the phenomena which enable us to form an estimate of the actual mass and dimensions of a molecule. It is to Clausius that we owe the first definite conception of the free path of a molecule and of the mean distance travelled by a molecule between success...
molecule 指质中保质的切化学性质,能独立存在的最小微粒,即分子。atom 指元素的最小粒子,其体积比molecule小。particle 指任何质的微粒,引申指任何小的部分。speck 般指“微点”或“微粒”,可引申指“斑点、污点”。grain 通常指能为肉眼清楚看到的颗粒,比上述几词所表“粒”的体积。
e.g. A methane molecule is composed of one carbon atom attached to four hydrogens. 甲烷分子由1个碳原子与4个氢原子构成。 atom 单语例句atom 1. The West suspects Iran is seeking to make atom bombs, a charge Tehran denies. 2. " It's like a big atom bomb has gone off, " he said....

Examples of substances that are not atoms include water (H2O),table salt(NaCl), and ozone (O3). Basically, any material with a composition that includes more than one element symbol or that has a subscript following anelement symbolis a molecule or compound rather than an atom....
Suppose the molecule contains A nuclei which, to simplify the discussion, are taken to be distinguishable, and that one nuclear coordinate is fixed in the process of elimination of the centre-of-mass motion. There are then (3A − 3) coordinates to be determined, whereas there are A(A ...
atom 指元素最小粒,其比molecule小。particle 指任何物质微粒,引申指任何小部。speck 一般指“微点”或“微粒”,可引申指“斑点、污点”。grain 通常指能为肉眼清楚看到颗粒,比上述几个词所表“粒”大。 联想词 atomic原,原能;molecule;electron;protons质;hydrogen氢;photon光;proton质;ion离;molecules学;boron...
