How many electrons can each orbital hold? - Answer Two How many electrons can be held in each sub shell? - Answer S - 2 P - 6 D - 10 F - 18 Put the sub shells in order do their energy, lowest to highest - Answer S, p, d and f How do we fill the p and d subshells - Answer singly first and then doubly What is an orbital? - Answer A region of space around the nucleus where there is a 95% chances of finding an electron What is the Aufbau principle? - Answer An electron...

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...

IB Chemistry Unit 2 SL Latest Version Rated A+ Emission spectrum An emission spectrum is produced when an atom moves from a higher to a lower level. The line emission spectrum of hydrogen provides evidence for __________________ which converge at _____________ The line emission spectrum of hydrogen provides evidence for the existence of electrons in discrete energy levels which converge at higher energies. Continuous spectrum All the colours / wavelengths present merge smoothly in...

Which orbital is the electron in? - l (L) value which orientation is the electron in? - m sub L value n value - use periodic table (period #) L value - what orbital its in (s, p, d, f) m sub L value - what orientation of the orbital is it in?---every electron in the atom has unique values for n, l, ml Electron configurations show... - which orbitals are in an atom and how the electrons fill the orbitals Electron configurations focus on... - ground state configuration (lowest en...

Pauli exclusion principle - ACCURATE ANSWERS no two electrons in an atom may possess identical sets of the four quantum numbers Aufbau principal - ACCURATE ANSWERS states that when the electrons of an atom are all in the ground state, they occupy the orbital's of the lowest energy, thereby minimizing the atoms total electronic energy. Hunds rule - ACCURATE ANSWERS when filling a set of degenerate orbitals, the number of unpaired electrons will be maximized and these electrons will have pa...

CHEM 120 Final Exam 5 GRADED A+ (ACTUAL EXAM ) Questions and Answers (Solved) 1. How many bonds can nitrogen have? Which rule or principle should beused? A) Five bonds; octet rule. B) Three bonds; octet rule. C) Three bonds; the Hund's rule. D) Five bonds; the Aufbau Principle. Answer: B 2. When two hydrogen atoms meet, they will attract to each other and form abond (and a H2 molecule).Why? A) Because electrons like to stay together. B) Because electrons like to be paired up. C) Bec...

Valence electron Electrons on the outermost energy level of an atom. The electrons in the highest energy level. Aufbau Principle the rule that electrons occupy the orbitals of lowest energy first. The principle used to add electrons to successive orbitals on an atom. “The orbitals with lower energies are filled before those with higher energies”.
