Concept introduction:
➢ The equations representing the changes that take place during radioactivity and other nuclear processes are called
➢ The nuclear equation should be balanced just like the chemical equations.
➢ In a balanced nuclear equation, the sum of the
➢ The atom undergoing nuclear disintegration is called parent nuclide and the products obtained are called daughter nuclide.
➢ The bombardment of neutron on nucleus increases the mass number by unit one.
➢ The identity and symbol of the daughter nuclide formed by an alpha decay can be deduced from the
➢ In an alpha decay, nucleus emits a particle with mass number 4 and atomic number 2 which is equivalent to helium nucleus. Thus, in an alpha decay, the mass number decreases by 4 and the atomic number decreases by 2.In a beta decay, nucleus emits an electron. During a beta decay, the mass number remains the same as electron has no protons or neutrons but atomic number increases by 1 as electron carries one unit of negative charge.
➢ The symbols of neutron, alpha particle, and beta particle are

Copper (II) oxide crystalizes in monoclinic unit cell (included below; blue spheres 2+ represent Cu²+, red - O²-). Use Kapustinski's equation (4.5) to calculate lattice energy for CuO. You will need some data from Resource section of your textbook (p.901). (4 points) CuOarrow_forwardWhat is the IUPAC name of the following compound? OH (2S, 4R)-4-chloropentan-2-ol O (2R, 4R)-4-chloropentan-2-ol O (2R, 4S)-4-chloropentan-2-ol O(2S, 4S)-4-chloropentan-2-olarrow_forward
- Use the reaction coordinate diagram to answer the below questions. Type your answers into the answer box for each question. (Watch your spelling) Energy A B C D Reaction coordinate E A) Is the reaction step going from D to F endothermic or exothermic? A F G B) Does point D represent a reactant, product, intermediate or transition state? A/ C) Which step (step 1 or step 2) is the rate determining step? Aarrow_forward1. Using radii from Resource section 1 (p.901) and Born-Lande equation, calculate the lattice energy for PbS, which crystallizes in the NaCl structure. Then, use the Born-Haber cycle to obtain the value of lattice energy for PbS. You will need the following data following data: AH Pb(g) = 196 kJ/mol; AHƒ PbS = −98 kJ/mol; electron affinities for S(g)→S¯(g) is -201 kJ/mol; S¯(g) (g) is 640kJ/mol. Ionization energies for Pb are listed in Resource section 2, p.903. Remember that enthalpies of formation are calculated beginning with the elements in their standard states (S8 for sulfur). The formation of S2, AHF: S2 (g) = 535 kJ/mol. Compare the two values, and explain the difference.
