Final answer:

Element Z is argon (Ar) with an atomic number of 18 and a mass number of 36, indicated by the symbol 36Ar18.

Step-by-step explanation:

An atom of element Z has two more protons and two more neutrons than an atom of 34S16. To find the symbol, atomic number, and mass number for atom Z, we first analyze the sulfur atom indicated. Sulfur (S) has an atomic number (Z) of 16, which is the number of protons, and a mass number (A) of 34, which is the total number of protons and neutrons.

Adding two more protons to the atomic number gives us 16 + 2 = 18. Therefore, the atomic number for element Z is 18. To find element Z's mass number, we add two more neutrons to the mass number of sulfur. Thus, 34 + 2 = 36, which is the mass number for atom Z.

The element with an atomic number of 18 is argon (Ar), so the symbol for atom Z is Ar, with a mass number of 36. The complete symbol for this atom of element Z is 36Ar18.
