Yes, selenium is a member of Group 16, also known as Group 6A, in the periodic table. This group is known as the chalcogens, and selenium shares similar chemical properties with the other elements in this group like oxygen and sulfur.
Phosphorus from IAmArchangel, but i wasn't signed in at the time
selenium has a -2 charge. when it forms a compound with another atom the charge of the compound should be zero unless it has a cahrge in its equation. when compounds form they try to be in the most stable state which is when all their valance elctrons are full which means the charge is zero.
Thorium is a member of the actinoids family and is placed in period 7.
The only element in nitrogen family with 16 neutrons is the element Phosphorus (symbol: P). However it is a solid at room temperature and not gas.

Nitrogen and Phosphorus.
Arsenic is a member of the metalloid family, which includes elements that have properties of both metals and nonmetals. It is located in Group 15 of the periodic table, along with elements like nitrogen and phosphorus.
Sulfur, Tellurium, Selenium, and Plutonium
Those elements are chalcogens, and the most significant other member of the group is oxygen. Polonium is also in the group, but from a chemical standpoint you can pretty much ignore it; it has no stable isotopes and exists only in trace amounts in nature (it's in the uranium-238 decay chain).
silicon
Group 15, the formal name being the Pnictogens. Group 15 was formerly called Group V or VA.
Selenium, tellurium, and polonium are metalliod semiconductors (that means, their electrical properties are between those of a metal and an insulator). Nevertheless, tellurium, as well as selenium, is often referred to as a metal when in elemental form.
All elements in the group of Nitrogen, such as Phosphorus and Arsenic, have five valence electron when in their natural state (that is, they have not have not gained or lost valence electrons). But as to the element in that group that has valence electrons in the third electron orbital, Phosphorus is the one you are looking for. To figure this out, just look at the Periodic Table of Elements, and you will see that Phosphorus is in the third row. Hope this helps!
The eight (8) grouping symbols related to set theory include the following: ∈ "is an element (member) of" ∉ "is not an element (member) of" ⊂ "is a proper subset of" ⊆ "is a subset of" ⊄ "is not a subset of" ∅ the empty set; a set with no elements ∩ intersection ∪ union
Fluorine The Halogen Family of elements is made up of the elements Fluorine, Chlorine, Bromine, Iodine and Astatine. Neon is one of the Inert or Noble gases. Lithium is a member of the Alkali Metal group of elements. Bismuth is in the same group of elements as Nitrogen, Phosphorus, Arsenic and Tin.neon
Uranium is a member of the actinides family of elements.
