What is the relationship between electronegativity and the polarity of a chemical bond? What does neon bond with? How many orbitals are in n=2? What type of bonding does ammonia have? What is outer electron configuration? What is a delocalized pi bond?
除了HF、H2O、NH3等三种氢化物能够形成氢键之外，在无机含氧酸、羟酸、醇、胺以及和生命有关的蛋白质等许多类物质都存在氢键。在一些矿物晶格中，如高岭土等也局部存在氢键。离子键一般情况下是金属与非金属所构成的化合物（铵根离子除外），其中，有一种元素完全失去电子形成相应的阳离子，同时另一种物...

store electrical energy in an electric field — a property determined by two factors: the molecule’s geometry and its dipole moment. A dipole moment refers to the measure of the molecular polarity, which indicates the separation of electrical charges within the molecule that forms an electric ...
If you are using a linear antenna, the polarity can have a significant impact on a system’s read range. The key to maximizing read range is to ensure an antenna’s polarity aligns with the polarity of the RFID tag. If these do not match up, for instance, a vertical linearly-polarized...
