<u>Answer:</u>
The correct answer option is a) collisions between the particles and surrounding molecules.
<u>Explanation:</u>
The collisions between the particles and surrounding molecules causes the Brownian motion of particles in a colloid.
Brownian motion is the irregular movement of the microscopic particles in a fluid which bombard into each other.
It basically is the result of the molecules of a dispersion medium colliding with the dispersed particles of the phase.
Answer:
Belong to the same group.
Explanation:
Different elements are most likely to react in similar ways when they belong to the same group.
This is because the elements in the same group always have similar number of valence electrons which implies that they all have the same number of electrons in their outermost shell. For example,barium (Ba), beryllium (Be), calcium (Ca), magnesium (Mg), radium (Ra), strontium (Sr) all have 2 electrons in their outermost shell and thus they belong to group 2 of elements which are known as Alkaline earth metals and they all tend to react in the same manner with other substances
