What elements in an element family have similar?
Valency
One important property of an element is its what?
I guess, the most fundamental is their valency. This dictates how many times it can bond to other elements. Elements with the same valency often share similar properties with other elements with the same valency. The periodic table is divided into 8 rows (and a D block). Each of these 8 rows have elements with similar properties, related to their valencies.
Which group of elements can have varying numbers of valence electrons metals noble gases non-metals?
