In the process of forming an ionic bond between sodium and chlorine, what happens to the electron configuration of sodium?
In the process of forming an ionic bond between sodium and chlorine, what happens to the electron configuration of sodium?
- Sodium's inner shell loses an electron to achieve a stable configuration
- Sodium loses its single outer electron to achieve a stable configuration (correct)
- Sodium gains an electron to achieve a full outer shell
- Sodium's outer shell remains unchanged, and it shares an electron with chlorine
What is the fundamental reason for the formation of an ionic bond between sodium and chlorine?
What is the fundamental reason for the formation of an ionic bond between sodium and chlorine?
- To achieve a balanced distribution of protons and neutrons
- To create a covalent bond between the two atoms
- To satisfy the octet rule and achieve a stable electron configuration (correct)
- To transfer energy from sodium to chlorine
Which of the following statements accurately describes the structure of an atom?
Which of the following statements accurately describes the structure of an atom?
- The electrons are randomly distributed around the nucleus without any specific arrangement
- The number of protons in the nucleus determines the chemical properties of the atom
- The nucleus contains both protons and neutrons, surrounded by electrons in energy levels or shells (correct)
- The nucleus contains only protons, while neutrons are located in the electron shells
