Educational worksheet introducing the periodic table, explaining its organization and providing activities for students to label elements and identify groups and periods.

Problem Overview:

The task involves understanding and labeling parts of the periodic table based on the information provided in the document. The goal is to identify specific elements, groups, periods, and categories (metalloids and nonmetals) using a periodic table.

Solution Explanation:

#### Step 1: Labeling the Information Indicated by Arrows
The image shows a small section of the periodic table with arrows pointing to specific pieces of information about the element "Carbon." Let's label each part:

1. Top Number (6): This is the atomic number of Carbon. It represents the number of protons in the nucleus of a Carbon atom.
2. Symbol (C): This is the chemical symbol for Carbon.
3. Name (Carbon): This is the element name.
4. Bottom Number (12.011): This is the atomic mass of Carbon. It represents the average mass of a Carbon atom in atomic mass units (amu).

So, the labeled sections are:
- Top: Atomic number (6)
- Middle: Chemical symbol (C)
- Bottom: Atomic mass (12.011)

#### Step 2: What To Do Instructions

##### Instruction 1: Write the symbols for 5 different elements
Element symbols are written with the first letter capitalized and any subsequent letters in lowercase. Here are examples of 5 different element symbols:
- Hydrogen: H
- Oxygen: O
- Nitrogen: N
- Sodium: Na
- Chlorine: Cl

##### Instruction 2: Find the numbers across the top (Groups)
The numbers across the top of the periodic table represent the groups or families of elements. These groups are numbered from 1 to 18. Each group contains elements with similar chemical and physical properties due to having the same number of valence electrons.

There are 18 groups on the periodic table.

##### Instruction 3: Find the numbers down the left side (Periods)
The numbers down the left side of the periodic table represent the periods or rows. These periods indicate the number of electron shells an element has.

There are 7 periods on the periodic table.

##### Instruction 4: Identify and color the metalloids
The metalloids are located along the zigzag line that starts at Group 13. The metalloids listed are:
- Boron (B)
- Silicon (Si)
- Germanium (Ge)
- Arsenic (As)
- Antimony (Sb)
- Tellurium (Te)
- Polonium (Po)

These elements should be colored purple on the periodic table.

##### Instruction 5: Identify and color the nonmetals
The nonmetals are located to the right of the zigzag line. These elements generally have properties such as low density, poor conductivity, and tend to form covalent bonds. Examples include:
- Hydrogen (H)
- Helium (He)
- Carbon (C)
- Nitrogen (N)
- Oxygen (O)
- Fluorine (F)
- Neon (Ne)
- Phosphorus (P)
- Sulfur (S)
- Chlorine (Cl)
- Argon (Ar)
- Selenium (Se)
- Bromine (Br)
- Krypton (Kr)
- Iodine (I)
- Xenon (Xe)
- Radon (Rn)

These elements should be colored yellow on the periodic table.

Final Answer:

1. Atomic number: 6
2. Chemical symbol: C
3. Element name: Carbon
4. Atomic mass: 12.011

For the "What To Do" instructions:
1. Example element symbols: H, O, N, Na, Cl
2. Number of groups: 18
3. Number of periods: 7
4. Metalloids: B, Si, Ge, As, Sb, Te, Po (Color purple)
5. Nonmetals: Elements to the right of the zigzag line (Color yellow)

Final Answer Boxed:
\boxed{6, C, Carbon, 12.011}
