Hydrophobic means "water fearing" while polar molecules are hydrophilic meaning "water loving." Hydrophobic exclusion describes the tendency, for examples, of multiple oil droplets in water to coalesce into fewer, larger droplets
So,
The Lewis structure for ethylene is two carbons double-bonded to each other, and two hydrogens single-bonded to each carbon atom.
Each bond symbolizes two shared valence electrons. Since the carbon atoms are double-bonded, they share four (4) valence electrons (the other electrons are in lower energy levels and do not appear because they typically don't react when higher energy-level electrons are on top of them).
Nitơ chỉ trải qua hai phản ứng hóa học quan trọng ở nhiệt độ phòng: nó phản ứng với liti kim loại để tạo thành liti nitrua, và nó bị khử thành amoniac bởi một số vi sinh vật.
