CLEP Chemistry Latest Update Graded A John Dalton Proposed that matter is composed of atoms; these atoms have different identities called elements, which combine to form compounds; measured masses of reactants and products. J.J. Thompson Observed deflection of particles in a cathode ray tube; proposed that atoms are composed of positive and negative charges; developed the plum pudding model of the atom Robert Millikan Calculated the charge-to-mass ratio of electrons using oil drops falling in ...

Entrance Exam Semmelweis 2024/2025 Questions with Complete Solutions Electron configuration for cations - Correct Answer Subtract 1 from exponent of highest n-value orbital (ex. remove from 4s before 3d) Ag+ = [Kr]5s^1 4d^9 Electron configuration for anions - Correct Answer Add 1 to closest orbital Cl- = [Ne]3s^2 3p^6 Atomic orbitals - Correct Answer s, p, d, f Primary vs secondary structures of proteins - Correct Answer Primary - AA chain (linked by peptide bonds) Secondary -...

CHEMISTRY A LEVEL WITH SATISFIED SOLUTIONS What are the two elements which are exceptions to the electron configuration? - CORRECT-The two exceptions for this is copper and chromium. In both cases, the 4s subshell contains only one electron, even though there are electrons in the 3d subshell. To explain this, its because the 3d subshell is more stable when it is either half full, or completely full. So in the case of chromium, by having only one electron in the 4s subshell, ...
