They are the electrons located in the outermost shell of an atom and are involved in bonding with other atoms. In this section, we will explore how to determine the number of valence electrons in In+, the cation of the element indium.
Explanation of the periodic table and its role in determining valence electrons
The periodic table is a fundamental tool in chemistry that organizes elements based on their atomic structure and properties. It consists of rows called periods and columns called groups. The group number of an element indicates the number of valence electrons it possesses.
Discussion on the group number of indium and its significance in determining valence electrons
Indium (In) is located in Group 13 of the periodic table, also known as the boron group. Elements in this group typically have three valence electrons. However, indium is an exception. It has an atomic number of 49, which means it has 49 electrons in total. To determine the number of valence electrons in In+, we need to consider its atomic structure.
Calculation of valence electrons in In+ based on its atomic structure
Indium has a configuration of 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10 5p^1. When indium loses one electron to become a cation (In+), it forms a stable electron configuration of 1s^2 2s^2 2p^6 3s^2 3p^6 4s^2 3d^10 4p^6 5s^2 4d^10.
To determine the number of valence electrons in In+, we subtract the number of electrons in the stable configuration from the total number of electrons in indium. In this case, the number of valence electrons in In+ is 3 (49 – 46 = 3). Therefore, In+ has three valence electrons.
By understanding the atomic structure of indium and its position in the periodic table, we can confidently determine the number of valence electrons in In+. This knowledge is essential for predicting its chemical behavior and interactions with other elements.
In conclusion, determining the number of valence electrons in In+ involves considering the element’s position in the periodic table and its atomic structure.
