Question

what is the electron configuration for nitrogen? 1s²2s²2p³ 1s²2s²2p⁶3s²3p⁵ 1s²2s²2p⁶3s²3p¹ 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰ 12) type the correct answers in the blanks. refer to the periodic table. follow the steps to write the electron configuration for germanium. how many electrons does germanium have? what period is germanium in? how many energy levels does germanium have?

Explanation:

Step1: Identify nitrogen's atomic number

Nitrogen (N) has an atomic number of 7, meaning it has 7 electrons.

Step2: Fill orbitals by Aufbau principle

Fill lower energy orbitals first: $1s^2$ (2 electrons), $2s^2$ (2 electrons), remaining 3 electrons go to $2p$, giving $2p^3$. Combine to get $1s^22s^22p^3$.

Step3: Find germanium's atomic number

Germanium (Ge) has an atomic number of 32, so it has 32 electrons.

Step4: Locate germanium on periodic table

Germanium is in period 4 (row 4) of the periodic table.

Step5: Count germanium's energy levels

The period number equals the number of occupied energy levels, so it has 4 energy levels.

Step6: Write germanium's electron configuration

Fill orbitals by Aufbau principle: $1s^22s^22p^63s^23p^64s^23d^{10}4p^2$

Answer:

1. Multiple choice answer: $\boldsymbol{1s^22s^22p^3}$
2. How many electrons does germanium have? $\boldsymbol{32}$
3. What period is germanium in? $\boldsymbol{4}$
4. How many energy levels does germanium have? $\boldsymbol{4}$
5. Electron configuration for germanium: $\boldsymbol{1s^22s^22p^63s^23p^64s^23d^{10}4p^2}$
