A molecule or compound is made when two or more atoms form a chemical bond, linking them together. The two types of bonds are ionic bonds and covalent bonds. The distinction between them has to do with how equally the atoms participating in the bond share their electrons. For example, ioni...
metallic bonds 金属键，金属单质或者合金才会有。ionic bonds 离子键，阴阳离子间形成的，有阳离子和阴离子，一般是盐和碱中才有。covalent bonds 共价键，非金属元素之间的化学键，在离子化合物中、共价化合物中都有可能有。比如氢氧化钠中，钠离子与氢氧根离子是离子键，氢氧根里氢原子与氧原子是共价...
Well, in this simulation, you will learn the basics of atomic bonding in ionic and covalent compounds and how to distinguish those compounds experimentally. Using this knowledge you'll help your friend to analyze two mysterious substances he received from an alchemist. By testing various physical ...
A bond’s strength describes how strongly each atom is joined to another atom, and therefore how much energy is required to break the bond between the two atoms. In this section, you will learn about the bond strength of covalent bonds, and then compare that to the strength of ionic bonds...

When atoms bond together, they create elements. The different types of bonds (ionic and covalent, polar and non-polar) have an impact on the elements they create. Understanding the types of bonds that create things can help us understand those things themselves. ...
The higher the {eq}\Delta EN {/eq}, the less "covalent" and more "ionic" the bond is. Between two identical atoms and up to {eq}\Delta EN=0.5 {/eq} the bond is non-polar. If the electronegativity difference is {eq}0.5<\Delta EN<2.0 {/eq}, the bond is polar covalent, and ...
Ionic Bond | Definition, Properties & Examples from Chapter 1 / Lesson 4 76K What is a chemical bond? What is the difference between an ionic and a covalent bond? Learn how ionic bonds are formed and what holds ionic compounds together. Related...
Hydrogen bonds are known to exhibit common features with ionic and covalent bonds. In quantum electrodynamics, the covalent bond has been demonstrated to display a spindle structure of the stress tensor density. Importantly, this spindle structure is also seen in the hydrogen bond, although the ...
3)蛋白质三级结构(Tertiary structure) 是蛋白质分子的3D结构, 主要由构成蛋白质的氨基酸的 R groups之间的相互作用形成。促成三级结构的 R groups 相互作用包括氢键(hydrogen bonds)、离子键(ionic bonds)、偶极-偶极相互作用(dipole-dipole interactions) 和非共价键(non-covalent bonds)。
