Effective Nuclear Charge and Periodic Trends Coulombs Law describes the interaction between two charges and varies by the magnitude of these charges and inversely with the distance between them. ? ∝ ?1?2/? For atoms, we’ll label the charges as the nuclear charge and electron charge. ? ∝ ?????????/? As you go up in atomic number (Z), the number of protons in the nucleus increases, making the charge on the nucleus increase, so that in general. ???? = ? ∙ (+1)...

X Y Z Both decrease Both increase O Qgets larger and gets smaller K gets larger and gets smaller Kremains constant and increases Kremains constant and a decreases 1 pts Question 5 You have a saturated solution of Ca(OH)2 in a flask, meaning there is some solid CaOH)2 sitting at...
Chem101 S18 W... 5. Lattice energy is the change i energy that is associated with forming a crystal line lattice of a compound from the gasenus ions. e.g. Na (B) + Cl.(s) ? NaCl(s}. A large negative value of lattice energy means that a lot nf eergy will be given off when the ions coe together to farnm the lattice. Choose the correct option in the statements below a. More energy will be given off when ons have a LARGER/SMALLER...
