Web20 jun. 2024 · A molecule is a neutral particle, composed of a set number of atoms bonded together. The particle of the substance is the molecule, rather than the atoms that make up the molecule. By contrast, ionic compounds are made up of an indeterminate number of ions, in a fixed ratio. The particle of the ionic substance remains the ion. WebMethane (CH 4 _4 4 start subscript, 4, end subscript), the simplest hydrocarbon molecule, consists of a central carbon atom bonded to four hydrogen atoms. The carbon and the four hydrogen atoms form the vertices of a three-dimensional shape known as a tetrahedron, which has four triangular faces; because of this, methane is said to have a tetrahedral …
Web• Chemical bonds—forces that hold atoms together • Covalent bonds—atoms share electrons and make molecules [independent units]; H 2, CO 2, H 2O, NH 3, O 2, CH 4 to name a few. • molecule--smallest unit of a compound that retains the chem. characteristics of the compound; characteristics of the constituent elements are lost. WebA molecule, normally, is a group of two or more atoms which are chemically bonded together.
