Electrons are one of the most important components in atoms. Compare and contrast how the electrons are organized in K (potassium), Al (aluminum), C (carbon), Cl (chlorine) and Ne (neon). Then explain how that electron structure leads these atoms to form or not form bonds with other atoms
Note you are asked to compare and contrast. That means noting both similar and different features. Electron notations will play an important part in your answer. You have to answer this question thoroughly and show me that you really understand how the electrons are organized in these atoms and how that effects how they bond.
I don't see any work or thought on your part. I suggest you start with the electron structure of the atoms in question. The 1s2 2s2 2p6 etc notation would be the best to use.
To compare and contrast the organization of electrons in potassium (K), aluminum (Al), carbon (C), chlorine (Cl), and neon (Ne), let's examine their electron configurations and orbital diagrams.
1. Potassium (K):

Comparisons:
1. All five elements have the same number of electrons in the first two energy levels (1s² 2s²) since they are in period 2.
2. Potassium, aluminum, and chlorine have additional electrons in the 3rd energy level (3s and 3p) compared to carbon and neon.
3. Chlorine has the highest number of valence electrons (7) among these elements, whereas neon has the least (8 valence electrons).
4. Neon is a noble gas, meaning it has a full outermost energy level.
Contrasts:
1. Potassium and chlorine have one electron in their 4s and 3p sublevels, respectively, while aluminum and carbon have one electron in their 3p sublevel, and neon has no electrons in the 3rd energy level.
2. Carbon has a different electron configuration as it has a half-filled p sublevel, making it more stable than the other elements.
Now, let's discuss how the electron structure influences these atoms' ability to form bonds:
1. Potassium (K):
- Its valence electron (in the 4s orbital) is easily lost, forming K⁺ ions, enabling it to readily bond with elements requiring one electron to achieve a stable octet.
2. Aluminum (Al):
- Aluminum tends to lose its three valence electrons from 3p¹, forming Al³⁺ ions, allowing it to bond with elements requiring three additional electrons to complete their octets.
3. Carbon (C):
- Carbon has four valence electrons, allowing it to form covalent bonds, either by sharing electrons with other atoms (thus completing its octet) or by forming multiple covalent bonds.
4. Chlorine (Cl):
- Chlorine tends to gain an electron, completing its 3p sublevel, and forming Cl⁻ ions. It readily bonds with elements needing one electron to complete their octets.
5. Neon (Ne):
- Neon has a full outermost energy level (octet) and is highly stable. Due to its complete electron configuration, it does not readily form chemical bonds with other atoms.
In summary, the electron organization in these atoms affects their ability to form bonds. Elements like potassium and chlorine readily form ions by gaining or losing electrons, while elements like aluminum and carbon bond by sharing electrons. Neon, being a noble gas, does not readily form chemical bonds due to its stable electron configuration.
