Questions and Answers

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?

  • 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?

  • 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
  • If an atom has 11 protons and 11 electrons, what is the most likely element it represents?
