Question

orbital notation & electron configurations of ions practice
eq: can i determine if an orbital notation is correctly or incorrectly written?
swbat determine if an orbital notation is correctly or incorrectly written by writing and discussing notes and examples and completing individual practice questions.
do now: what is the electron configuration of a chlorine atom in the ground state?
a. 2 - 7
b. 2 - 8 - 5
c. 2 - 8 - 7
d. 2 - 8 - 8
orbital notation rules: circle the correct diagram below.

1. paulis exclusion principle -
2. aufbaus principle -
3. hunds rule -

complete the chart below using the information you just learned
determine the last letter number sequence for the following elements.
ex: mg 3s²

1. i
2. cs

determine which element these letter number sequences refer to.

1. 4p³
2. 6p⁴

configuration writing practice
write a ground state electron configuration for each neutral atom. ground state means that all of the lowest possible energy levels (up to the proper number of electrons for the element) are filled.

1. ar:
2. co:

Explanation:

Explicación:

Paso1: Saber que cloro tiene 17 electrones

Los primeros 2 electrons van al nivel 1s, los siguientes 8 al nivel 2 (2s²2p⁶) y los últimos 7 al nivel 3 (3s²3p⁵), es decir 2 - 8 - 7.

Respuesta:

C. 2 - 8 - 7
