WebAtom: The smallest particle of an element, which may or may not have an independent existence, is called an atom. Molecule: The smallest particle of a substance capable of independent existence is called a molecule. Molecules are formed by the combination of the atoms of the same element or different elements. Molecules are of two types: WebAtoms are described as “the fundamental building blocks of matter.” It is the smallest constituent unit of matter that possesses chemical element properties. Atoms do not exist in isolation; instead, they combine to form ions and molecules, which then combine in large numbers to form the matter we see, feel, and touch.

WebThree types of matter are solids, liquids, and gases. Comprehending the particle nature of matter is significant. Particles that makeup matter are not ‘ small solid bits ‘ or ‘ small liquid drops, ‘ but atoms and molecules. … WebAll the matter around us are made of tiny particles called atoms and molecules. While atoms of an element represent only one kind of particle, molecules are made of either the same or different kinds of one or more particles. This difference defines the two classes of compounds, namely heteroatomic and homoatomic molecules.

WebSolution. The interparticle force of attraction can be defined as the force of attraction exerted between particles (atoms, molecules). For eg, In solid particles are very close so their interparticle space is very little while gas particles are very far from each other so their interparticle space is large. Suggest Corrections. WebFirst, the chlorine atoms are balanced. The equation becomes Cl 2 + KBr → 2 KCl + Br 2; Now, the bromine atoms must be balanced, there is one bromine atom on the reactant side and 2 on the product side. Therefore, there must be 2 Br molecules on the reactant side. The chemical equation is transformed into Cl 2 + 2 KBr → 2 KCl + Br 2
