Chapter 9 1. Na+ has the same electron configuration as which noble gas? A) Ne b)...
When writing the electron configuration for gold, Au, Z = 79, which noble gas will be used to represent the core electrons? (writing the electron configuration as (noble gas) + valence electrons). Ne Xe Ar ООО ORn Kr
Electron transfer is the term for this process. The resulting anion and cation are attracted by Coulombic forces and an ionic compound is formed. Ionic compounds are neutral: the number of electrons lost in forming the cation(s) must equal the number gained in forming the anion(s). For example, Aluminum (Al, Z = 13, Group 3A or 13) will lose 3 electrons to become Al3+ which is isoelectronic with Neon (Ne), its closest noble gas. To form an ionic compound those...
A. If the following elements were to form an ionic compound, which noble-gas configuration would they most likely attain? Drag the appropriate elements to their respective bins. B. An unknown element, X, reacts with lithium to form the compound Li2X. In other compounds this element also can accommodate up to 12 electrons rather than the usual octet. What element could Xbe? If the following elements were to form an ionic compound, which noble-gas configuration would they most likely attain? Drag...
What is(are) the noble gas(es) that have the same electron configuration as each of the ions in the compound formed from Z=38 and Z=34?
13) In chemical formulas for ionic compounds which is written first? a) Cation b) Oxygen c) Anion d) Noble gas 14) Metal ions with an invariant charge are termed? a) Type I cations b) Type II cations c) Metalloids d) Transition metals 15) In ionic compounds the ending of the anion (not a polyatomic) is always changed to? a) -ous b)-ic c) -ide d) Smith for reasons of security 16) A cluster of two or more atoms covalently bonded together...
