Question
Consider the reaction of sodium metal with chlorine gas to from NaCl as shown below. How does each elements in the compounds NaCl attain an octet of electrons? 2 Na(s) + Cl_2 rightarrow 2 NaCl(s) A sodium atom and a chlorine atom share two electrons. A sodium atom loses an electron and the chlorine atom accepts the electron. A chlorine atom loses an electron and the sodium atom accepts the electron. A sodium atom loses an electron and the chlorine atom loses seven electrons. A sodium atom gains seven electrons and the chlorine atom loses seven electron Given the three statements below, pick the best answer. Cl has a higher electron affinity than P. The ionization energy for Si is greater than that for P^+. The electron affinity for O is greater than that for Se. (i) and (iii) are true, (ii) is false (ii) and (iii) are true, (i) is false (i) and (ii) are true. (iii) is false only (ii) is true all three are true The ground state electron configuration is^2 2s^2 2p^6 3s^2 3p^2 would be connect for which species listed below? Al P P^+ S none of these What is the correct Lewis dot symbol for a nitride ion, N^3? Which species is isoelectronic with Al? Si^2+ Si^- P^2- P^2+ none of these Arrange the species Cl^-1, K^+1, and S^-2 in terms of increasing radil. Cl^-1Explanation / Answer
