Understanding the Periodic Table

The periodic table 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. The elements are listed in order of increasing atomic number (number of protons in the nucleus) and are grouped into rows called periods and columns called groups or families.

Locating Sodium on the Periodic Table

Sodium is a chemical element with the symbol Na and atomic number 11. To locate sodium on the periodic table, we need to follow these steps:

Identify the Group: Sodium is an alkali metal, which means it belongs to Group 1 of the periodic table. Group 1 elements are located in the far left column of the periodic table.
Identify the Period: Sodium is located in Period 3 of the periodic table. Period 3 elements are located in the third row of the periodic table.
Locate the Element: Now that we know sodium is in Group 1, Period 3, we can locate it on the periodic table. Sodium is the first element in Group 1, Period 3.

Why is Sodium in Group 1?

Sodium is in Group 1 because it has one electron in its outermost energy level, which makes it highly reactive. Group 1 elements are known as alkali metals because they readily lose one electron to form a positive ion (a cation). This is why sodium is highly reactive and tends to lose one electron to form a sodium ion (Na+).

Why is Sodium in Period 3?

Sodium is in Period 3 because it has an atomic number of 11. The periodic table is arranged in order of increasing atomic number, so sodium is located in Period 3 because it has 11 protons in its nucleus.

Conclusion

In conclusion, sodium is located in Group 1, Period 3 of the periodic table. This is because it has one electron in its outermost energy level, making it highly reactive, and it has an atomic number of 11, which places it in Period 3.
