Will give brainliest for the quickest and correct answer An atom X has 5 energy levels of electrons outside its nucleus and 74 neutrons inside its nucleus. Identify this atom
a. I
b. Cd
c. Ca
d. Fr
e. P

Iodine

Explanation:

Iodine is located in the 5th period, meaning that it will have 5 energy levels.

Additionally, Iodine has an atomic mass of about 127 atomic mass units, and since it has 53 protons, it will have 74 neutrons.

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.
