Question

Research the organization of the periodic table of element and give 4 examples of how the elements are classified.

Answer 1

The periodic table of elements classifies elements in order of increasing atomic number into periods and groups, with elements in the same group having similar chemical properties. Elements are classified as metals, nonmetals, and metalloids, or as a main group, transition, and inner transition metals. Groups are identified from 1-18 and include specific designations for particularly important groupings like alkali metals, alkaline earth metals, halogens, and noble gases.

Step-by-step explanation:

The periodic table of elements is a scientific tool that helps scientists understand the relationships among various elements. It organizes elements in order of increasing atomic number in rows known as periods and columns known as groups. Elements in the same group have similar chemical properties.

Now, let's give four examples of how elements are classified:

1. Metals, Nonmetals, and Metalloids: Elements are classified as metals, nonmetals and metalloids based on their shared properties. Most of the elements in the table are metals.
2. Main Group Elements, Transition Metals, and Inner Transition Metals: The broadest classification of the table divides it into blocks. The s-block and p-block elements are called main group elements, the d-block is called transition metals, and the f-block is known as inner transition metals.
3. Groups: Groups are columns in the periodic table. Groups are also numbered from 1-18 from left to right.
4. Specific Groups: There are specific groupings such as the alkali metals (Group 1), alkaline earth metals (Group 2), halogens (Group 17), and noble gases (Group 18). These groupings contain elements that share especially important properties.
