Quantum orbitals - Study guides, Class notes & Summaries

Protons correct answers defines the element; positive charge; equal to the atomic number Neutrons correct answers equal to mass number-number of protons; neutral charge Electrons correct answers negative charge; dependent on the charge of the atom Cations correct answers Positively charged ions Anions correct answers Negatively charged ions Isotopes correct answers when the number of neutrons varies but it has the same number of protons ex) Ne-20 and Ne-22` What was believed un...

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 ...

principal quantum number (n) - ANSWER symbolized by n, indicates the main energy level occupied by the electron. positive integers (1,2,3...) shell - ANSWER set of orbitals with the same principal quantum number, n. atomic orbital - ANSWER a region of space in which there is a high probability of finding an electron. mathematical function that describes the behavior of an electron in an atom, wave function. angular momentum quantum number (l) - ANSWER the quantum number that indicates t...

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, ...

Lights acts as what? - Answer-Particle and wave. Wavelength - Answer-The distance (m) of waves from peak to peak. Short: x-ray (red), long: infrared (blue) Short - higher energy Long - lower energy Frequency (V) - Answer-The number of wavefronts per second. Highest: x-ray Velocity of Light - Answer-C = 3.00 X 10^8 = wavelength X frequency Amplitude - Answer-The intensity, height of peaks of waves. Highest: blue light Energy of Wave (J) - Answer-Increases as frequency increases and as wa...

principal quantum number (n) - -symbolized by n, indicates the main energy level occupied by the electron. positive integers (1,2,3...) shell - -set of orbitals with the same principal quantum number, n. atomic orbital - -a region of space in which there is a high probability of finding an electron. mathematical function that describes the behavior of an electron in an atom, wave function. angular momentum quantum number (l) - -the quantum number that indicates the shape of an orbital. (0,...
