Use The Periodic Table To Answer The Following Questions:1. Atoms Of Which Element Contain 25 Protons? A. Magnesium (Mg) B. Aluminum (Al) C. Tin (Sn) D. Manganese (Mn)2. Which Element Has An Atomic Number Of 16? A. Oxygen (O) B. Sulfur (S)

The periodic table is a fundamental tool in chemistry that helps us identify and understand the properties of elements. It is a tabular arrangement of the known chemical elements, organized by their atomic number (number of protons in the nucleus), electron configuration, and recurring chemical properties. In this article, we will use the periodic table to answer two questions about elements and their properties.

Question 1: Atoms of which element contain 25 protons?

To answer this question, we need to look at the periodic table and find the element with an atomic number of 25. The atomic number of an element is equal to the number of protons in the nucleus of an atom of that element. Let's take a look at the periodic table:

Looking at the periodic table, we can see that the element with an atomic number of 25 is Manganese (Mn). Therefore, the correct answer is:

• D. Manganese (Mn)

Question 2: Which element has an atomic number of 16?

To answer this question, we need to look at the periodic table and find the element with an atomic number of 16. Let's take a look at the periodic table:

Looking at the periodic table, we can see that the element with an atomic number of 16 is Sulfur (S). Therefore, the correct answer is:

• B. Sulfur (S)

Conclusion

In conclusion, the periodic table is a powerful tool that helps us identify and understand the properties of elements. By using the periodic table, we can easily answer questions about elements and their properties. In this article, we used the periodic table to answer two questions about elements and their properties. We found that the element with an atomic number of 25 is Manganese (Mn) and the element with an atomic number of 16 is Sulfur (S).

The periodic table is a fundamental tool in chemistry that helps us identify and understand the properties of elements. It is a tabular arrangement of the known chemical elements, organized by their atomic number (number of protons in the nucleus), electron configuration, and recurring chemical properties. In this article, we will explore the periodic table in more detail and learn how to use it to identify elements.

The Structure of the Periodic Table

The periodic table is arranged in a grid of rows and columns. The rows are called periods, and the columns are called groups. The elements are arranged in the periodic table in order of increasing atomic number, which is the number of protons in the nucleus of an atom of that element.

The Periods of the Periodic Table

The periods of the periodic table are the rows of elements. Each period starts with an alkali metal and ends with a noble gas. The periods are numbered from 1 to 7, and each period contains a different number of elements.

The Groups of the Periodic Table

The groups of the periodic table are the columns of elements. Each group contains elements with similar properties. The groups are numbered from 1 to 18, and each group contains a different number of elements.

How to Use the Periodic Table to Identify Elements

To use the periodic table to identify elements, you need to know the atomic number of the element. The atomic number is the number of protons in the nucleus of an atom of that element. You can find the atomic number of an element by looking at the periodic table and finding the element with the same number of protons in its nucleus.

Example: Finding the Element with an Atomic Number of 25

To find the element with an atomic number of 25, you need to look at the periodic table and find the element with 25 protons in its nucleus. Let's take a look at the periodic table:
