How many valence electrons would an element with an electron configuration ending in p5 have?

7 valence electrons

Explanation:

Electronic configuration represents the total number of electrons that a neutral element contains. We add all the superscripts to know the number of electrons in an atom.

The electrons are filled according to Afbau's rule in order of increasing energies.

Valence electrons are the number of electrons constituting the outermost shell of an atom.

Thus the electronic configuration could be :

Thus the outermost orbit is 2 which has (2+5)= 7 electrons. Thus there are 7 valence electrons.

a non redox reaction occurs when there is not a transfer of electrons. for redox reactions, which are reduction-oxidation reactions, a change in the oxidation number occurs. elements that are reduced gain electrons, and elements that are oxidized lose electrons.

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.
