On the Periodic Table, what chemical symbol matches each description? 1. the alkaline earth metal in the second row 2. the halogen in the fourth row 3. the lanthanide whose name begins with the letter “N”
1. The diazenide ion, N22-, is a recently isolated compound, discovered to ionically bind to alkaline earth metals. a. Draw an MO diagram for N22-. Your diagram should include symmetry labels for all atomic and molecular orbitals, as well as their relative energies. b. Determine the bond order of N22- c. Is N22-a diamagnetic or paramagnetic compound? d. In contrast with N2-, the analogous carbon and oxygen based ions, peroxide (022) and acetylide (C2have been known to exist for a...
For each of the following examples, (a) Draw a molecular orbital diagram. Include both the atomic orbitals that combine and the molecular orbitals that are formed. Clearly show the relative energies of all orbitals. Label all orbitals and show the appropriate number of electrons in the molecular orbitals. Give both labeling conventions (e.g. sigma2s and 1sigmag) for each of the molecular orbitals. You do not have to sketch the actual orbitals. (b) Give the bond order. (c) Indicate the effect...
Worksheet 8.1“Lewis Dot Structures and Formal Charge Calculations” 1. Goal: Draw Lewis Dot Diagrams and determine either formal charge or bond polarity. 2. Why: to understand chemical bonding, you must be able draw three dimensional representations to show bond angles and strength of chemical bonds. Students also need to be able to use Calorimetry equations to calculate enthalpy of reactions. Atomic number (2) Chemical symbol Be1 9.01 - Atomic mass 3A 4A 5A 6A beryllium (defined in section 4.9) 13...

Figure 1:
1) Please draw the free-body diagram of mass M in Figure 1(a). The diagram should include the pulling force F, gravitational force Mg, normal force N, and friction force fk. 2) Consider the graph in Figure 1(b). Please explain why the average of pulling force F in Region (ii) can be regarded as the kinetic friction force fx. (You may refer to the free body diagram in Question 1.) F个 (i) rest constant speed Force sensor h.

Pick 10 polyatomic ions. Draw Lewis strucures for each(1). Include major resonance forms (2) with formal charges (3). Identify the VSEPR notation (4), shape (5), and hybridization (6) of the central atom(s) of each molecule or ion. List all types of van der Waal forces expected in a pure sample of each molecule (7). If you could show the VSEPR notation in the form of AxE: A being the central atom, x being the bonded pairs to the central atom,...
