Worksheet 5: Quantum numbers, Electronic Configurations and Periodic Trends. 1. The following table describes selected orbits of a single atom. Fill in the missing values. 2. Write either the corresponding electron configuration for each element or the neutral element described by the given configuration. Tc. Br- Cu. As+. O2- Cr.
QUANTUM NUMBERS WORKSHEET. 1. State the four quantum numbers, then explain the possible values they may have and what they actually represent. n – Pricipal Quantum Number: represents the energy level the electron is in, linked to the periods of the periodic. Can be 1 to 7.
Which of the following are permissible sets of quantum numbers for an electron in a hydrogen atom. For those combinations that are permissible, write the appropriate designation for the subshell to which the orbital belongs (ex. 1s) [2, 1, 1, +1/2] [1, 0, ‐1, ‐1/2] [4, 2, ‐2, +1/2] [3, 3, 0, ‐1/2]
A typical electron configuration consists of numbers, letters, and superscripts with the following format: A number indicates the energy level (The number is called the principal quantum number.). A letter indicates the type of orbital; s, p, d, f. A superscript indicates the number of electrons in the orbital.
QUANTUM NUMBERS WORKSHEET Name ________________________________. State the four quantum numbers and the possible values they may have. Name the orbitals described by the following quantum numbers. a. n = 3, L = 0. b. n = 3, L = 1. c. n = 3, L = 2. d. n = 5, L = 0.
changes the bond angle. For every lone pair present, the bond angle between covalent bonds is reduced by 2.5 o . This can be seen by looking at methane, ammonia and water in the table below. All molecules have 4 electron pairs, but the bond angle decreases by 2.5° with each lone pair of electrons. Molecule Shapes
