The name of the group is the oxygen family. The valence number for elements in that group are -2. (gain or share two electrons) Oxygen, sulfur and selenium are nonmetals. Tellurium and Polonium are metalloids.

So the most nonmetallic element is fluorine (which is to say, it has the highest electronegativity) and it is in the upper right hand corner - except for the noble gases which are inert, and are even farther to the right.

Is the element sodium metallic or nonmetallic?
It is Metallic. Meaning it is a metal. It's in the group of elements called the Alkali Earth Metals.
Are there are more nonmetallic elements than metallic elements?
No. There are much more metallic elements than non metallic elements. All of Group 1, 2 and 5 are metals. All of the transition metals (inc. Lanthanides and Actinides) are metals. Also, most elements in group 6 and 7 are metals.
What describes a property of all of the Group 4 A elements?
they are metals.
What kind of elements can form ions with more than one charge?
Transition elements are the major group of elements with this property.
Which element in Group 15 has the most nonmetallic properties?
bismuth
What group consists of the most reactive nonmetallic elements?
Group 17, the halogens
