the covalent bonds within the molecules to make them more reactive. Enzymes do both. The reactants (known in biochemistry as substrates) are attracted to the enzyme protein and form ionic bonds and/or H-bonds to the protein. The reaction between the substrates ...
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...
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...
The covalent-ionic transition, the chemical activity of metal-semiconductor interfaces, and other topics related to the problem of Schottky barrier formation are discussed from a unified standpoint. Passive interfaces are defined as those where no valence bonds are formed between the adsorbed atoms and...

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...
Are the bonds in NaOCH3 ionic or covalent? Explain. Ionic bond:It is a chemical attraction where atoms are connected by oppositely charged ions. In this type of bonding, valence electron transfer is complete between atoms. The atoms become positively charged ions after losing electrons, while ...
