Physical states (gas, liquid, or solid) of the representative elements in the fourth period ( K, Ca, Ga, Ge, As, Se, Br ) at 1 atm and 25 ° C should be given. Concept Introduction: Three states of matter : Solid, liquid and gas. Solid Possess a definite volume and definite shape. Particles are closely packed together and unable to move about very much. Particle of a solid have very low kinetic energy. Liquid Liquid possess a definite volume, bit indefinite shape. Particles are less loosely bound than solid and have more kinetic energy than solid. The liquid particle is not held in regular shape. Gas Gas possess an indefinite volume and indefinite shape. Particles have a great deal of space between them and have high kinetic energy. Gas particle have enough kinetic energy to overcome intermolecular forces that hold by solid or liquid or together. Across the period, physical state of elements goes from solid then to liquid and to gas.

Question

Definition Definition Substance that constitutes everything in the universe. Matter consists of atoms, which are composed of electrons, protons, and neutrons. Different atoms combine together to give rise to molecules that act as a foundation for all kinds of substances. There are five states of matter based on their energies of attraction: solid, liquid, gases, plasma, and BEC (Bose-Einstein condensates).
