Which type of element is shown in blue boxes in the middle of this periodic table?

A. Nonmetals
B. Metals
C. Noble gases
D. Metalloids

Answer :

The answer B.metals


Identify the location of the blue boxes in the periodic table. The elements in the middle of the periodic table typically correspond to the transition metals
2 Recall the classification of elements in the periodic table:
Nonmetals are found on the right side.
Metals are primarily located on the left and center.
Noble gases are found in Group 18 (far right).
Metalloids are located along the zig-zag line between metals and nonmetals.
Since the blue boxes are in the middle of the periodic table, they represent metals, specifically transition metals
To determine the type of elements shown in the blue boxes in the middle of the periodic table, let's discuss the general layout and categorization of elements within the periodic table.

1. Periodic Table Structure: The periodic table is organized into columns called groups and rows called periods. Elements are classified into several categories based on their properties, such as metals, nonmetals, noble gases, and metalloids.

2. Location Description: The middle section of the periodic table primarily contains elements known as the transition metals. These elements typically occupy groups 3 through 12 on the periodic table.

3. Properties of Transition Metals:
- They are good conductors of electricity and heat.
- They tend to have high melting and boiling points.
- These metals are malleable and ductile.
- They often form colored compounds and are widely used in various industrial applications.

4. Answer Exploration: Given that the elements in the blue boxes are situated in the middle of the table, this aligns with the location of the transition metals. These elements are known for the properties mentioned above and predominantly occupy this section.

5. Conclusion: Therefore, the type of elements shown in the blue boxes in the middle of the periodic table is B. Metals. Specifically, these are transition metals, which are a subset of metals.
