Explanation:

Step1: Recall atomic numbers and element names

For element symbols, we use the periodic table to find atomic numbers (Z) and names. For example, C (carbon) has Z=6; Fe (iron) has Z=26; H (hydrogen) has Z=1; Cu (copper) has Z=29; He (helium) has Z=2; Au (gold) has Z=79; Si (silicon) has Z=14; O (oxygen) has Z=8; Al (aluminum) has Z=13; Ag (silver) has Z=47; Ca (calcium) has Z=20.

Step2: Fill in each blank

1. C: Z=6, name=Carbon
2. 26: symbol=Fe, name=Iron
3. H: Z=1, name=Hydrogen
4. 29: symbol=Cu, name=Copper
5. He: Z=2, name=Helium
6. Au: Z=79, name=Gold
7. 14: symbol=Si, name=Silicon
8. O: Z=8, name=Oxygen
9. 13: symbol=Al, name=Aluminum
10. Ag: Z=47, name=Silver

(For the lower Ca: Z=20, name=Calcium; Al: Z=13, name=Aluminum)

Answer:

1. Atomic number: 6, Name: Carbon
2. Symbol: Fe, Name: Iron
3. Atomic number: 1, Name: Hydrogen
4. Symbol: Cu, Name: Copper
5. Atomic number: 2, Name: Helium
6. Atomic number: 79, Name: Gold
7. Symbol: Si, Name: Silicon
8. Atomic number: 8, Name: Oxygen
9. Symbol: Al, Name: Aluminum
10. Atomic number: 47, Name: Silver

(For lower Ca: Atomic number: 20, Name: Calcium; Al: Atomic number: 13, Name: Aluminum)
