Describe how the electronic structure of these elements changes across the period 3

Image result for Describe how the electronic structure of these elements changes across the period 3

In the whole of period 3, the outer electrons are in 3-level orbitals. ... In fact the increasing nuclear charge also drags the outer electrons closer to the nucleus. That increases ionisation energies still more as you go across the period.

Explanation:

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
