ROck (metal rock ) Vs Hip hop, rap ?
in group two elements the second electron enters the s orbital and increased charge on the nucleus creates more attractive force on electrons in the atom around so that the density increases and the elements behave as hard solids than the first group elements.
They have fuller electron shells? That might be why, can't remember exactly :)
Ahhh ... some must fall by the wayside, including the Sons of Odin. Paul Stanley and Viincent 'Alice Cooper' Furnier advance, for mine.
Since group 2 metals have more valence electrons than group 1 metals, they form stronger metallic bonds. Consequentially, they are harder and have higher melting points.
