Answer the following Questions: 1) How do you determine the charge for the transition metals when given the name? 2) How do you determine the charge for the transition metals when given the formula?

What is the fundamental difference between an organic substance and an inorganic substance? Write chemical formulas of three inorganic molecules that contain carbon.

1. Hydrogen is a Group I element and each hydrogen will contribute I valence electron. Carbon is a Group (Roman numeral) element and each carbon will contribute ___ (number) electrons. Every oxygen atom in a compound will contribute valence electrons. Chloromethane has the molecular formula . Its skeleton is and the number of valence electrons may be determined as follows. There are three hydrogen atoms, each of which contributes 1 valence electron; the single carbon contributes 4 electrons; and the single chlorine atom contributes 7 electrons, making a total of 14 . A convenient tabular form of this calculation is

Name each of the following binary compounds, using the periodic table to determine whether the compound is likely to be ionic (containing a metal and a nonmetal) or nonionic (containing only nonmetals). Fe3P2d.PbCl4 CaBr2e.S2F10 N2O5f.Cu2O

Given that the periodic table is an organizational scheme for the elements, what might be some other logical ways in which to group the elements that would provide meaningful chemical information in a periodic table of your own devising?

For each of the following atomic numbers, use the periodic (able to write the formula (including the charge) for the simple ion that the element is most likely to form. a. 53 c. 55 e. 9 b. 38 d. 88 f. 1.13

Open the Build an Atom simulation (http://openstaxcollege.org/l/16PhetAtomBld) Drag protons, neutrons, and electrons onto the atom template to make a neutral atom of Oxygen-16 and give the isotope symbol for this atom. Now add two more electrons to make an ion and give the symbol for the ion you have created.

For the following processes that show the formation of ions, use the periodic table to indicate the number of electrons and protons present in both theionand theneutral atomfrom which the ion is made. a.CaCa2++2e b.P+3eP3 c.Br+eBr d.FeEe3++3e e.AlAl3++3e f.N+3eN3

Which of tire following explain how an ion is formed'? Explain your answer. a. adding or subtracting protons to/from an atom b. adding or subtracting neutrons to/from an atom c. adding or subtracting electrons to/from an atom
