The collision must have sufficient energy as well.  If sufficient energy is not present the activation energy will not be over come and the bonds in the reactants will not be broken.

I hope this helps.  Let me know if anything is unclear.

<u>Answer:</u> The correct answer is the particles must have adequate velocity.

<u>Explanation:</u>

According to collision theory, a product is formed only when the collisions between the reactants is effective.

There are 2 factors on which the effective collisions depends:

  • <u>Energy factor: </u>This factor says that the colliding molecules must have energy greater than the threshold energy.
  • <u>Orientation factor:</u> This factor says that the colliding molecules must have a proper orientation at the time of collision.

Velocity is related to kinetic energy by the formula:

E=\frac{1}{2}mv^2

where,

E = kinetic energy of the particle

m = mass of the particle

v = velocity of the particle

So, from this we can say that the velocity of the particles must be sufficient enough for collision to be elastic.

Hence, the correct answer is the particles must have adequate velocity.

yulyashka [42]

Answer:

The smallest constituent of an element is termed as an atom. According to Jaiden, an atom comprises two subatomic particles and three prime parts, however, this is incorrect as an atom comprises three subatomic particles and two main parts. The three subatomic particles are the protons, electrons, and neutrons. All these parts are smaller in comparison to an atom, thus, they are considered as subatomic particles.  

To be considered as an atom, an atom is needed only electrons and neutrons, like hydrogen exhibit one electron and one proton. On the other hand, the overall charge of the atom is not affected by the presence of neutrons, it is the subatomic particle that only enhances the mass of the atom.
