Question
The electrons of one atom are attracted to the protons of another. When atoms combine, there is a tug of war over the valence electrons. The combining atoms either lose, gain, or share electrons in such a way that they complete their outer shells. Whether atoms gain, lose, or share electrons depends how tightly they hold onto their own electrons and how strongly they pull on the electrons of another atom. Answer the questions below based on the information above and on your knowledge of chemistry. What is the charge on a proton? What is the charge on an electron? Why do an atom's electrons revolve around its protons instead of drifting away? Why are the electrons of one atom attracted to the protons of another? What happens when two atoms get near each other that causes them to bond? How are the elements sodium and chlorine, classified? What would happen during a tug of war between sodium and chlorine over each others outer electrons? Why? How do sodium and chlorine combine?Explanation / Answer
q 3) centrifugal force of the revolving electron just exactly balances the attractive force of the protons (nucleus) so electron not drifting away.
q ) The electron in each atom starts to notice the proton of the other atom. As a result, it becomes attracted not only to its own proton, but to the proton of the other atom as well. As a result, the electrons will tend to spend more of their time in between the two protons, instead of each one qua orbiting its own proton and bond form
q 6) sodium is an alkali metal and chlorine is a halogen gas.
q 7) Sodium would lose one electron and chlorine would gain one electron. End of contest. Sodium is oxidized, chlorine is reduced and complete the outer shells.
q 8) When sodium and chlorine atoms come together to form sodium chloride (NaCl), they transfer an electron. The sodium (Na) atom transfers one electron to the chlorine (Cl) atom, so that they both have full outer shells.
