The electron configurations of two unknown elements X and Y are shown. X: 1s22s22p63s1
Y: 1s22s1

Which statement is most likely correct about the two elements?

neutrons are in the middle of the atom and the electrons, which are much smaller.

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.

the increase of protons   hope this
