The comparison of the side of the sodium ion with sodium atom is to be predicted. The explanation for the corresponding prediction is to be stated. Concept introduction: Every element wants to attain an electronic configuration same as noble gas configuration, to do so elements either gain electrons or lose electrons. When an atom of element gains electrons, it forms an anion. When an atom of element loses electrons, it forms a cation.

Question

Chemists in the 19th century constructed an evacuated glass tube with wires inserted in both ends. When an electrical current was generated at the anode, a 'cathode ray' would pass to the cathode creating a fluorescent glow. These experiments helped chemists better understand the nature of the electron. J.J. Thomson added a magnetic field to a cathode ray tube to show that the ray would bend. His experiments demonstrated that the rays were negatively charged particles. He then calculated the mass to charge ratio of the electric ion (electron). According to his calculations, how massive was the electron relative to the hydrogen ion? Voltage Source A) The same size B) ~1000 times larger C) ~1000 times smaller + S D) ~10 times larger Anode Cathode E) ~10 times smaller

Two sets of ionizations are shown in the tables below. Complete the tables by ordering each set of ionizations by increasing amount of energy required. In other words, for each set choose "1" next to the ionization that would require the least energy, "2" next to the ionization that would require the next least energy, and so on. ionization + Cs Cs + e + Xe → Xe te + Kr→ Kr + e energy required ? ? ? O ionization He → He + e Br→ Br te + Fr → Fr + e energy required ? ? ?

The first ionization energy of sodium is 496 kJ/mol. Use Coulomb’s law to estimate the average distance between the sodium nucleus and the 3s electron. How does this distance compare to the atomic radius of sodium? Explain the difference.
