The tenth element in the periodic table is part of thea)First periodb)...
Explanation:
The periodic table is a tabular arrangement of chemical elements organized based on their atomic number, electron configuration, and recurring chemical properties. It is divided into rows called periods and columns called groups.
Periods:
Periods are the horizontal rows in the periodic table. There are a total of 7 periods in the periodic table, each represented by a number. The period number indicates the number of energy levels or electron shells an element's atoms have.
Groups:
Groups are the vertical columns in the periodic table. There are a total of 18 groups in the periodic table, each represented by a number or a letter. Groups are also known as families because elements in the same group often have similar properties.
The Tenth Element:
The tenth element in the periodic table is neon (Ne). Neon has an atomic number of 10, which means it has 10 protons in its nucleus.
Position of Neon:
Neon is located in the second period of the periodic table. The second period consists of elements with atomic numbers 3 to 10. Elements in the second period have two energy levels or electron shells. Neon specifically has its 10 electrons distributed in these two energy levels.
Importance of Periods and Groups:
Periods and groups in the periodic table provide valuable information about an element's properties, including its atomic structure, electron configuration, and chemical behavior. Elements in the same period have the same number of electron shells, while elements in the same group have similar electron configurations and exhibit similar chemical properties.
Conclusion:
In conclusion, the tenth element in the periodic table, neon (Ne), is part of the second period. Understanding the organization of the periodic table, including periods and groups, is essential in studying and predicting the properties of different elements.

Explanation of the Tenth Element in the Periodic Table
The tenth element in the periodic table is Neon (Ne). To understand why it belongs to the second period, we need to examine its electron configuration and the arrangement of elements in the periodic table.
- Electron configuration: The electron configuration of Neon is 1s² 2s² 2p⁶. This configuration indicates that Neon has a total of ten electrons, with two electrons in the 1s orbital, two in the 2s orbital, and six in the 2p orbital.
- Periods in the periodic table: Periods in the periodic table represent the energy levels of the electron orbitals. Each period starts with the filling of a new principal energy level. The first period comprises elements with electrons filling the 1s orbital, the second period comprises elements with electrons filling the 2s and 2p orbitals, and so on.
- Neon's position in the periodic table: Since Neon has its highest energy electron in the 2p orbital, it belongs to the second period. The elements in the second period include Lithium (Li), Beryllium (Be), Boron (B), Carbon (C), Nitrogen (N), Oxygen (O), Fluorine (F), and Neon (Ne).
In conclusion, the tenth element in the periodic table, Neon, belongs to the second period (Option C) due to its electron configuration and the arrangement of elements in the periodic table.
