Question

what is the long - hand electron configuration of rhenium, re? enter the electron configuration using no spaces or superscripts using lower case letters (e.g., 1s²2s²2p⁴ would be entered as 1s22s22p4). question 6 1 pts what is the short - hand electron configuration of iridium, ir? enter the electron configuration using no spaces or superscripts using the proper case letters (e.g., he2s²2p⁴ would be entered as he2s22p4). question 7 1 pts

Explanation:

Step1: Recall rhenium's atomic number

Rhenium (Re) has an atomic number of 75. Electrons are filled according to the Aufbau principle, Pauli - exclusion principle, and Hund's rule.

Step2: Write long - hand electron configuration

The electron configuration is 1s22s22p63s23p64s23d104p65s24d105p66s24f145d5.

Step3: Recall iridium's atomic number

Iridium (Ir) has an atomic number of 77.

Step4: Write short - hand electron configuration

The nearest noble gas before Ir is Xe (atomic number 54). So the short - hand electron configuration is [Xe]4f145d76s2.

Answer:

Question 1: 1s22s22p63s23p64s23d104p65s24d105p66s24f145d5
Question 2: [Xe]4f145d76s2
