Part 1: Identify the symbol for each element

We need to match each element name with its corresponding chemical symbol. Here are the answers:

1. Oxygen → O
2. Hydrogen → H
3. Chlorine → Cl
4. Sodium → Na
5. Fluorine → F
6. Carbon → C
7. Helium → He
8. Nitrogen → N
9. Copper → Cu
10. Sulfur → S
11. Magnesium → Mg
12. Manganese → Mn
13. Neon → Ne
14. Bromine → Br
15. Phosphorus → P
16. Silver → Ag
17. Lead → Pb
18. Iron → Fe
19. Calcium → Ca
20. Potassium → K

Part 2: Fill in the chart below

The chart requires us to fill in the missing information for elements based on their names, symbols, atomic numbers, periods, and groups. The first row (Sodium) is already completed as an example.

#### Chart Information:
- Element: Name of the element.
- Symbol: Chemical symbol of the element.
- Atomic Number: Number of protons in the nucleus.
- Period: Row number in the periodic table.
- Group: Column number in the periodic table.

#### Filling in the chart:

| Element | Symbol | Atomic Number | Period | Group |
|---------|--------|---------------|--------|-------|
| Sodium | Na | 11 | 3 | 1 |
| Hydrogen | H | 1 | 1 | 1 |
| Krypton | Kr | 36 | 4 | 18 |
| Gold | Au | 79 | 6 | 11 |
| Bromine | Br | 35 | 4 | 7 |

#### Explanation:
1. Hydrogen (H):
- Atomic Number: 1
- Period: 1 (first row)
- Group: 1 (alkali metals)

2. Krypton (Kr):
- Atomic Number: 36
- Period: 4 (fourth row)
- Group: 18 (noble gases)

3. Gold (Au):
- Atomic Number: 79
- Period: 6 (sixth row)
- Group: 11 (transition metals)

4. Bromine (Br):
- Atomic Number: 35
- Period: 4 (fourth row)
- Group: 7 (halogens)

Part 3: Give an atom with the following characteristics

We need to identify elements that fit specific categories based on their properties or positions in the periodic table.

#### Characteristics and Examples:
1. Halogen: Elements in Group 17 (the halogens).
- Example: Chlorine (Cl)

2. Chalcogen: Elements in Group 16 (the chalcogens).
- Example: Sulfur (S)

3. Alkali metal: Elements in Group 1 (the alkali metals).
- Example: Lithium (Li)

4. Actinide series: Elements in the bottom row of the periodic table, starting with Actinium (Ac).
- Example: Uranium (U)

5. Lanthanide series: Elements in the second row of the f-block, starting with Lanthanum (La).
- Example: Cerium (Ce)

6. Alkaline Earth metal: Elements in Group 2 (the alkaline earth metals).
- Example: Magnesium (Mg)

7. Transition metal: Elements in Groups 3–12 (the d-block).
- Example: Iron (Fe)

8. Nobel gas: Elements in Group 18 (the noble gases).
- Example: Argon (Ar)

Final Answer Summary:

1. Symbols for Elements:
- Oxygen: O, Hydrogen: H, Chlorine: Cl, Sodium: Na, Fluorine: F, Carbon: C, Helium: He, Nitrogen: N, Copper: Cu, Sulfur: S, Magnesium: Mg, Manganese: Mn, Neon: Ne, Bromine: Br, Phosphorus: P, Silver: Ag, Lead: Pb, Iron: Fe, Calcium: Ca, Potassium: K

2. Chart Completion:
- Hydrogen: Symbol = H, Atomic Number = 1, Period = 1, Group = 1
- Krypton: Symbol = Kr, Atomic Number = 36, Period = 4, Group = 18
- Gold: Symbol = Au, Atomic Number = 79, Period = 6, Group = 11
- Bromine: Symbol = Br, Atomic Number = 35, Period = 4, Group = 7

3. Atoms with Specific Characteristics:
- Halogen: Chlorine (Cl)
- Chalcogen: Sulfur (S)
- Alkali metal: Lithium (Li)
- Actinide series: Uranium (U)
- Lanthanide series: Cerium (Ce)
- Alkaline Earth metal: Magnesium (Mg)
- Transition metal: Iron (Fe)
- Nobel gas: Argon (Ar)
