Question

directions: in the hog hilton activity you learned how to fill in electron orbital diagrams. you can use an electron orbital diagram to write an electron configuration. for each number of electrons given, identify the element. then, write the electron configuration. 1. 11 electrons element: electron configuration: 2. 22 electrons element: electron configuration: 3. 6 electrons element: electron configuration: 4. 35 electrons element: electron configuration: 5. 14 electrons element: electron configuration: questions: 1. compare electrons with the hogs in the hog hilton. a. what are the similarities? b. what are the differences? 2. to go between floors on the hog hilton did the hogs need to use energy? 3. would electrons need to use energy to go between orbitals? 4. if only 1/2 the energy necessary to go between the 1s and 2s orbital was available, will an electron go to the 2s orbital?

Explanation:

Step1: Recall element - electron number relation

The atomic number of an element is equal to the number of electrons in a neutral atom.

Step2: Identify element for 11 electrons

Sodium (Na) has an atomic number of 11. The electron - filling order is $1s<2s < 2p<3s$. The electron configuration is $1s^{2}2s^{2}2p^{6}3s^{1}$.

Step3: Identify element for 22 electrons

Titanium (Ti) has an atomic number of 22. The electron configuration is $1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{2}$.

Step4: Identify element for 6 electrons

Carbon (C) has an atomic number of 6. The electron configuration is $1s^{2}2s^{2}2p^{2}$.

Step5: Identify element for 35 electrons

Bromine (Br) has an atomic number of 35. The electron configuration is $1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{5}$.

Step6: Identify element for 14 electrons

Silicon (Si) has an atomic number of 14. The electron configuration is $1s^{2}2s^{2}2p^{6}3s^{2}3p^{2}$.

Answer:

1. Element: Sodium (Na), Electron Configuration: $1s^{2}2s^{2}2p^{6}3s^{1}$
2. Element: Titanium (Ti), Electron Configuration: $1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{2}$
3. Element: Carbon (C), Electron Configuration: $1s^{2}2s^{2}2p^{2}$
4. Element: Bromine (Br), Electron Configuration: $1s^{2}2s^{2}2p^{6}3s^{2}3p^{6}4s^{2}3d^{10}4p^{5}$
5. Element: Silicon (Si), Electron Configuration: $1s^{2}2s^{2}2p^{6}3s^{2}3p^{2}$
