- Moving on, Electronegativity is an atoms ability to attract more electrons.
- Once again Coloumbic attraction has an impact as a bigger coloumbic attraction means an atoms electronegativity is weaker
- This time the trend going down a group is a decrease, for example Li's electronegativity of 1 decreases to a 0.8 for K
- And the trend going right is an increase! For example, Li's 1 electronegativity becomes F's 4.
- The reason for the decrease going down is because the radius is increasing meaning the atoms ability to attract electrons is weakened.
- While the reason it increases going right is because we are gaining more protons whilsts not increasing our radius, meaning our ability to attract electrons increases.
- The shielding effect is another important thing to mention. In essence its a reduction in the effective nuclear charge of the electron cloud.
- Since the efficiency is dropped our ability to attract electrons worsens.
- And the electron cloud is where said electrons reside, around the nucleus.
- Oh yea! the nuclear charge is a measure of the protons in the nucleus ability to attract the negative electrons around it
- Goodbye to you all, may the guidance you attained today aid you in your studies
- Im pretty certain thats all I have to teach you mortals. I hope you will be content with this new information.
- As if! We barely scratched the surface. But I must get going, it was fun teaching you mortals goodbye.
