Although there is still some debate over the formal distinction, a molecule is a group of two or more atoms joined by chemical bonds, whereas a compound is a substance formed by the chemical bonding of more than one type of element that exists in a fixed proportion. Molecular compounds and ...
A monoatomic molecule is 1 that includes only 1 element's atom. E.g., Na,He and so on. A diatomic molecule is 1 that has 2 atoms in an element's molecule. E.g., O2 as well as N2. A polyatomic molecule is 1 that has more than 2 atoms in an element's molecule. E.g., ...
A molecule can be thought of as the smallest unit of a substance that retains its chemical properties. It is made up of atoms that have been chemically bonded by two or more. Atoms from the same element or from other elements can combine to form molecules. For example, oxygen gas (O2) ...
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。
To put it simply, atoms are the most basic units of elements, or matter that cannot be chemically broken down further; and molecules are the most basic units of compounds, or matter that is made up of more than one element chemically bonded together. Chemical bonds occur through the sharing...

The terms molecule, compound, and atom can be confusing! Here's an explanation of what a molecule is with some examples of common molecules.
Moleculesare units of matter that are made up of more than one atom. Atoms chemically bond together to form molecules. Often this chemical combination or reaction is between atoms of more than oneelement. To put it simply, atoms are the most basic units of elements, or matter that cannot ...
Molecule definition: the smallest physical unit of an element or compound, consisting of one or more like atoms in an element and two or more different atoms in a compound.. See examples of MOLECULE used in a sentence.
Water, the most common liquid, the “universal solvent”, is just a little “extraordinary”, and this exceptional nature of the “liquid element” is essential for our universe. It is not normal that a substance in its solid state should be less dense than in the liquid, but if on one...
