Trends

Every graph has a trend. Even the craziest most unorthodox graph that's composed of limitations of values and additions of multiple function has a trend, if you force it to have one.

Luckily for us, the trends of the periodic table are less difficult to decipher, and also less complex. So here they are, short and sweet.

  • Metallic properties increase right to left, up to down
  • Atomic radii increases right to left, up to down
  • Atomic Size increases right to left, up to down
  • The least reactive elements are groups 7 and 8. It increases in reactivity in both directions, increasing going down on the left side and up on the right side.
  • The melting point is lowest on both sides of the periodic table and increases as it approaches the centre.
  • Ionization energy increases going down to up and left to right. 
  • Electronegativity increases going down to up and left to right
Not so bad is it? 

I hope you've enjoyed these bite-sized blogs, because we're getting tested on them next week. And for good luck, have a rabbit.
