Answer: Option (1) is the correct answer.

Explanation:

Kinetic energy is the energy that arises due to the motion of molecules. Average kinetic energy involves the sum of vibrational, translational and rotational kinetic energies.

When we decrease the temperature then the movement of molecules starts to decrease. As a result, there will be decrease in the average kinetic energy of its particles.

Thus, we can conclude that as the temperature of a substance decreases, the  average kinetic energy of its particles decreases.

[50 PTS] show does the arrangement of elements on the periodic table relate to their chemical properties?
slava [35]

YES, the arrangement of elements on the periodic table relate to their chemical properties

Explanation:

As you move across a period, the atomic radius decreases due to the increase in atomic mass and hence attraction of orbitals by the increasingly positive nucleus. Therefore, the atoms become increasingly harder to lose electrons (due to increasing ionization energy) in their valence shell and more likely to take up electrons in chemical reactions.

The lower you go down the periodic table the higher the reactivity of the atoms. This is because they have more electron shells and the valence electrons are shielded from the atomic nuclei by underlying orbitals. This means that the valence electrons are easily lost (ionization energy is low) and can, therefore, react fast in chemical reactions.
