    People wondering about the inconsistencies in the graph:
    Im begining grade 10 now so maybe not the best explanation, but when going from ions in the S-orbital (first two) to the P-orbital (3rd one) there is a dip in the graph, because that single electron is kinda lonely in that entire P-orbital, so it's easier to remove him than the others
    And then the second dip in a period is when there are 3 electrons in the P-orbital (aka when there is only one electron in every hourglass shape) so they have a special kind of stability where they dont wanna share their P-Orbitals with another electron(one orbital can hold two electrons), so when another one is added its easily removable in order to regain that special stability of the 3 electrons in the p orbital
    Hope it helps in a way

    'cation' is derived from the greek 'κάτω', meaning 'down', while 'anion' is derived from 'άνω', meaning 'up'. thus, it's more like 'down-ions' and 'up-ions'.

      @mariageorgiadou1198 7 ปีที่แล้ว +10

      oleksijm yes you can cal also remember it as cation , "cat" which is a likebale animal by many people, and anion which creates an aural image of an "onion" which stinks and has more of a negative image

    There is a reason every student searches anything on youtube and the reason is teachers can't teach a single word of that thing. And here you are who made a video 6 years ago and still helping me. And the voice is just.

    • @mubashirali4340
      @mubashirali4340 7 ปีที่แล้ว +3

      Elements in solid state are more stable. So first an atom in solid or liquid state is converted into gaseous form by sublimation and then its electron is removed.

    • @mahinurrashid5892
      @mahinurrashid5892 7 ปีที่แล้ว +1

      element should be converted to gaseous state to weaken the forces of attraction so it is easier to remove electrons
