The iron atoms absorb enough energy to lose three electrons each and become iron(III) ions. The octa-atomic sulphur molecules absorb enough energy to become sulphur atoms. These atoms each gain two electrons to become sulphide ions with a -2 charge each. Since electrons are conserved, 1½ times as many sulphur atoms so react as do iron atoms. These ions now form a solid and give up energy. The overall process gives up energy (enough so that some of the solid goes off as a smoke).
Depending on how far you are in chemistry, you could get by with this explanation, or you could discuss whether the iron(III) sulphide formed is a simple ionic solid as described or something a bit more complicated.
Particles move at a faster rate at higher temperatures, than they do at lower temperatures. This is do to the fact that heat is a form of energy. When a particle has more energy is moves faster.
is it true the space between gas particles becomes very large
Thomson did the experiment various times to observe if the particles behave the same way. How they did he determined they were the same kind later called electrons.
their internal structure makes them behave in a similar way.
The ability to cause others to behave as they might not otherwise choose to do is manipulation.
The particles are moving rapidly
In a chemical reaction, particles, such as atoms and molecules, collide with one another, breaking existing bonds and forming new ones. This interaction typically requires energy to overcome activation barriers, leading to the rearrangement of particles into different substances. The behavior of these particles is influenced by factors like temperature, concentration, and the presence of catalysts, which can speed up the reaction. Ultimately, the result is the transformation of reactants into products through the reorganization of atomic structures.
When air particles are under pressure, they are pushed closer together, increasing their density. This results in an increase in the number of collisions between particles, creating higher pressure within the system. If the pressure is released, the particles will spread out to lower the density and pressure back to equilibrium.
Kinetic Theory.
Electrons behave like particles and waves simultaneously, exhibiting wave-particle duality. They can exhibit wave-like interference patterns and particle-like behaviors such as interacting with other particles by exchanging photons.
In a solid, particles are closely packed together and vibrate in fixed positions. They have a fixed shape and volume, and only have slight movements. The particles do not have enough energy to move around freely like in liquids or gases.
Group I cations are typically spectator ions in a reaction
Particles behave differently when observed due to the phenomenon known as wave-particle duality. This means that particles can exhibit both wave-like and particle-like behavior depending on how they are observed. When particles are observed, their wave-like properties collapse into a specific position or state, causing them to behave differently than when they are not being observed. This is a fundamental aspect of quantum mechanics and has been demonstrated through various experiments.
In a sense the answer to your question is "yes." What quantum mechanics actually tells us is that at the fundamental level objects of very small mass sometimes behave as particles and sometimes behave as waves. Trying to determine whether they're "really" one or the other is like trying to distinguish between six and half a dozen.
Electrons exhibit characteristics of both waves and particles, known as wave-particle duality. They can behave as waves in certain experiments and as particles in others.
Electromagnetic waves can behave like particles known as photons. Photons are the quanta of light and exhibit both particle-like and wave-like properties.
