Oxygen is a and therefore when it forms an ion. metal; gains electrons metalloid; loses electrons metal; loses electrons nonmetal; gains electrons nonmetal; loses electrons
7. True or False: When an atom forms an ion, only the number of valence electrons changes; the number of protons and neutrons remains the same as in the non-ionic (1 pt.) form.
Type the formula for the ion that forms when a neutral atom undergoes each of the following changes. Neutral F atom gains one electrons to form: Neutral Mg atom loses two electrons to form:
Electron configurations of transition metal ions Zinc is an essential mineral of great biological and health importance. In fact, it is the second most abundant transition metal after iron in our body. Most exists as Zn2+ ion in active site of enzymes, and they (more than 300) perform an array of functions. a. What is the electronic configuration of the Zn atom. b. Here comes the irritating part in chemistry. Although the 3d orbitals are placed higher in energy than...

1.) Identify the most likely transition metal, M and provide a suitable explanation: a.) A complex ion with the formula [M(H2O)6]3+, where M is a second row transition metal, that has a LFSE (CFSE) of -2.4 (ignoring pairing and exchange energies). Hint: only the low spin configuration is observed in second row transition metals. b.) A tetrahedral complex ion with the formula [MCl4]-, where M is a first row transtion metal, that has five unpaired electrons.
2.) Give the point group assignment of the following transition metal compounds: a.) trans- [PtCl2Br2]the ion has a square planar shape with Pt as the central atom b.) [CO(NH3)sBr]? the ion has an octahedral shape with Co as the central atom. Treat the NH3 groups as a large, spherical atom attached to the Co. c.) [Fe(CO)s) the compound is a square pyramidal shape, with Fe as the central atom. Assume that the Fe-C-O bond angle for each attached CO is...
