Flashcards do conjunto (19)
- 1What is the value and shape of the s orbital?s has a value of 0 and is shaped like a sphere
- 2How many electrons can occupy any one atomic orbital?2
- 3What is the value and shape of the p orbital?p has a value of 1 and is shaped like a dumbbelll
- 4What is the value and shape of the d orbital?d has a value of 2 and is shaped like a clover
- 5What is the value and shape of the f orbital?f has a value of 3 and is shaped kinda weird
- 6What is m, and what does it represent?Magnetic Quantum Number
Describes the orientation of the orbital in space; in other words, whether an orbital lies along the x-, y-, or z-axis on a three-dimensional graph, with the nucleus of the atom at the origin. - 7What are the possible values of m?m can take on any value from -l to l
- 8What does n represent?The Principal Quantum Number (n) represents the energy level (shell) of each orbital, which increases with its distance from the nucleus.
- 9What are orbitals with the same n value called?an electron shell
- 10What are the different subshells?s, p, d, and f
- 11What are the different atomic shells?K(1), L(2), M(3), and N(4)
- 12What is an Orbital?The region(s) of sub-shells surrounding an atom that contain electrons.
- 13What are Bohr's Postulates?(1) an electron moves around the nucleus in a circular orbit, (2) an electron’s momentum in the orbit is quantized, and (3) the change in an electron’s energy as it makes a quantum jump from one orbit to another is accompanied by the emission or absorption of a photon
- 14What is the Aufbau Principle?The German Aufbauprinzip (building-up principle), also called the Aufbau rule, states that electrons fill atomic orbitals of the lowest available energy levels before occupying higher levels.
- 15Heisenberg uncertainty principleThe German physicist Werner Heisenberg, that the position and the velocity of an object cannot both be measured exactly, at the same time, even in theory
- 16What do the boxes represent in an electron configuration?The distribution of electrons, where each box represents an orbital and the arrows within the boxes represent the electrons in that orbital
- 17In what way do electrons travel around the nucleus?In circular orbits around the nucleus
- 18What is an anomalous electron configuration?Some atoms, such as transition metals and elements in the lanthanide and actinide series, do not adhere strictly to Hund's rule and Pauli's principle. The reason the anomalies are observed is the unusual stability of both half-filled pnd completely filled subshells
- 19what is the ground-state electron configurationthe arrangement of electrons around the nucleus of an atom with lower energy levels. In orbitals, electrons naturally fall towards the lowest energy state or ground state
