Which of the Following Is the Correct Electron Configuration for TC?
The element TC refers to the chemical symbol for Technetium, a synthetic element known for its radioactive properties. Technetium is the first element in the periodic table that does not occur naturally. In this article, we will discuss the correct electron configuration for Technetium and provide a comprehensive understanding of electron configurations. We will also answer some frequently asked questions about this topic.
Electron configuration is a representation of the arrangement of electrons in an atom or ion. It provides valuable information about an element’s chemical properties and behavior. The electron configuration follows a specific pattern based on the Aufbau principle, Pauli exclusion principle, and Hund’s rule.
To determine the correct electron configuration for Technetium (TC), we need to consider its atomic number, which is 43. The atomic number represents the number of protons in an atom’s nucleus, and for a neutral atom, it also corresponds to the number of electrons.
The electron configuration for Technetium can be determined by filling the orbitals in the order of increasing energy levels. The energy levels are represented by the numbers 1, 2, 3, and so on, with each level having specific sublevels and orbitals.
The electron configuration for Technetium is: 1s^2 2s^2 2p^6 3s^2 3p^6 3d^10 4s^2 4p^6 4d^5 5s^2.
Let’s break it down:
– The first shell (1s) can hold a maximum of 2 electrons, so we have 1s^2.
– The second shell (2s and 2p) can hold a maximum of 8 electrons. As a result, we have 2s^2 and 2p^6.
– The third shell (3s, 3p, and 3d) can hold a maximum of 18 electrons. Therefore, we have 3s^2, 3p^6, and 3d^10.
– The fourth shell (4s, 4p, and 4d) can hold a maximum of 32 electrons. We have 4s^2, 4p^6, and 4d^5.
– Lastly, the fifth shell (5s) can hold up to 2 electrons, and we have 5s^2.
Now, let’s move on to the FAQs section:
