**Understanding the Periodic Table: A Guide to Identifying Elements**

The periodic table is a comprehensive chart that organizes elements based on their atomic number, electron configuration, and recurring chemical properties. It is a powerful tool for chemists and scientists to identify and understand the properties of various elements. In this article, we will explore the periodic table and use it to answer a specific question: which element is placed in the same period as ruthenium but has a higher atomic number?

The Periodic Table: A Brief Overview

The periodic table consists of rows called periods and columns called groups or families. Elements in the same period have the same number of electron shells, while elements in the same group have the same number of electrons in their outermost shell. The periodic table is arranged in a way that elements with similar properties are placed together.

Ruthenium: An Overview

Ruthenium is a chemical element with the atomic number 44 and the symbol Ru. It is a hard, silver-white transition metal that belongs to the platinum group. Ruthenium is a rare element and is found in small amounts in platinum ores. It has a number of unique properties, including high melting and boiling points, and is used in a variety of applications, including catalysis, electronics, and medical devices.

From the above list, we can see that the element with the next highest atomic number in the same period as ruthenium is Osmium (Os), with an atomic number of 76.

Conclusion

In conclusion, the element placed in the same period as ruthenium but with a higher atomic number is Osmium (Os). This is because osmium is located in the same period as ruthenium (period 5) and has a higher atomic number (76) than ruthenium (44). The periodic table is a powerful tool for chemists and scientists to identify and understand the properties of various elements. By using the periodic table, we can easily identify the element in the same period as ruthenium but with a higher atomic number.
