Question: Which of the following elements is most likely to form an ionic bond? (2023)

Options:

Correct Answer: Sodium

Exam Year: 2023

Solution:

Sodium is most likely to form an ionic bond as it readily loses an electron to form Na+.

Which of the following elements is most likely to form an ionic bond? (2023)

Step 1: Understand what an ionic bond is. An ionic bond is formed when one atom gives up one or more electrons to another atom.
Step 2: Identify the elements involved. Look for elements that are metals and non-metals, as metals tend to lose electrons and non-metals tend to gain them.
Step 3: Focus on sodium (Na). Sodium is a metal that is in Group 1 of the periodic table.
Step 4: Recognize that sodium has one electron in its outer shell. It is easier for sodium to lose this one electron than to gain seven more to fill its outer shell.
Step 5: When sodium loses its one electron, it becomes positively charged (Na+). This is a key characteristic of elements that form ionic bonds.
Step 6: Compare sodium with other elements. Look for other elements that might gain electrons instead of losing them, as they are less likely to form ionic bonds.
