Explanation:

1. Silver's atomic symbol is Ag, which is derived from its Latin name "Argentum".
2. Mercury's atomic mass is approximately 200.59 (from the periodic table).
3. Ni is the symbol for Nickel.
4. The element with atomic number 17 is Chlorine (Cl).
5. Transition metals have partially filled d - orbitals. Examples include Fe (Iron) and Cu (Copper).
6. Cu (Copper), Ag (Silver), and Au (Gold) are in Group 11.
7. Noble gases are inert. Examples are He (Helium) and Ne (Neon).
8. Halogens are in Group 17. Examples are F (Fluorine) and Cl (Chlorine).
9. The element with atomic number 74 is Tungsten (W).
10. Copper's atomic mass is approximately 63.55 (from the periodic table).
11. The last element in Period 4 is Krypton (Kr).

12 - 15: In the periodic table key box, the top number (6) is the atomic number, the letter (C) is the atomic symbol, the name (Carbon) is the element name, and the bottom number (12.01) is the atomic mass.
