The answer is: Nitrogen.
Silver is a metal element. Atomic number of it is 47.
For any periodic element, its atomic number correlates directly with its number of protons. Thus, an element with an atomic number of six has six protons, with an atomic number of seven, seven protons, and so on.
Nitrogen

Lithium is an element with an atomic number of 3 and an atomic mass of 7.
Silver (Ag) has an atomic number of 47 and is used in photography.
Silver, with symbol Ag.
Cobalt, is in the metal family. The atomic number for the element of cobalt, (word steaming from the German meaning for evil spirit, and goblin) is twenty seven.
Could you please re-ask your question in a better manner, because that question does not make sense. Are you trying to ask the atomic mass of the element with the atomic number of 7? or are you just stating that there is an element with the atomic number of 7? because that is not a very good question.
The atomic number is the number of protons in an atom of an element.
Atomic number = Number of protons
The atomic number of the element with the symbol Be (Beryllium) is 4.
