Question

write full electron configurations for b. express your answer in complete form in order of increasing orbital energy as a string without blank space between orbitals. for example, 1s²2s² should be entered as 1s^22s^2.

Explanation:

Step1: Determine the atomic number of B

B (boron) has an atomic number of 5.

Step2: Fill orbitals according to Aufbau principle

Electrons fill orbitals in order of increasing energy: \(1s < 2s < 2p\).
First, fill the \(1s\) orbital: \(1s^2\).
Then, fill the \(2s\) orbital: \(2s^2\).
Finally, fill the \(2p\) orbital with the remaining \(5-(2 + 2)=1\) electron: \(2p^1\).

Answer:

\(1s^22s^22p^1\)
