    this took me ages to understand back in high school and i still didn’t get it because i thought science was supposed to be learned not by UNDERSTANDING it but remembering very detail in the textbook. People like you proved me otherwise and now i have a completely different view on things. THANK YOU.

    can u please help with a question i’ve been stuck on for the longest time,
    “In terms of atomic structure explain why the ionization energy tends to get smaller as the atomic number increases within a group”

    • The education elixir 2 years ago

      Because protons and electrons are more closer so more attraction and less energy
