Most electronegative elements belong to ___________ group.

Answer

To determine which group contains the most electronegative elements, we can follow these steps:

### Step 1: Understand Electronegativity
Electronegativity is the tendency of an atom to attract electrons towards itself when it is part of a compound. Elements with high electronegativity have a strong ability to gain electrons.

**Hint:** Remember that electronegativity is about how strongly an atom can attract electrons.

### Step 2: Identify Groups in the Periodic Table
The periodic table is organized into groups (columns) and periods (rows). Groups contain elements with similar properties.

**Hint:** Familiarize yourself with the periodic table and the characteristics of different groups.

### Step 3: Analyze Group 17 (Halogens)
Group 17 of the periodic table is known as the halogens. The elements in this group include fluorine, chlorine, bromine, iodine, and astatine.

**Hint:** Recall that halogens are known for their reactivity and tendency to gain electrons.

### Step 4: Determine Electron Gain Requirement
Elements in Group 17 need to gain only one electron to complete their outer electron shell (octet). This makes them highly electronegative because they have a strong drive to gain that one electron.

**Hint:** Consider how many electrons each group needs to gain or lose to achieve a stable electron configuration.

### Step 5: Conclusion
Since Group 17 elements need only one electron to complete their octet, they are the most electronegative elements in the periodic table.

**Final Answer:** Most electronegative elements belong to **Group 17**.
