INVISIBLE MECHANICS
"don't be a normie, i guess"
,INVISIBLE MECHANICS
, General Information
Group 1 and 2
Group 1 (Alkali metals) : - Li, Na, K, Rb, Cs, Fr
Group 2 (Alkaline earth metals) : - Be, Mg, Ca, Sr, Ba, Ra
Francium is radio active, Fr has a t1/2 of 21 minutes
Beryllium is rare (only 10^-10 % of igneous rocks)
Li shows similarities to Mg and Be to Al due to similar size and e/m ratio
Group 1 : Alkali Metals ------> Highly electropositive metals and lose 1 electrom to form M+ ions
Periodic Trends
Atomic/Ionic Radii : Increase down the group : [Li<Na<K<Rb<Cs<Fr]
IE/IP : decrease down the group : [Li>Na>K>Rb>Cs>Fr]
Hydration Enthalpy : Decrease down the group [Li>Na>K>Rb>Cs>Fr]
