Need this asap, I'll give brainliest. Determine which of the following electron configurations are not valid: State which rule has been violated.

ANSWER

1)4d^10 should be 3d^10

2) 3s^2 is impossible and 3d^5 it should be p not d

3) Ra is not a noble gas

4)Valid

5)Element can’t be its own electron configuration.

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.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
