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 ...
The two main types of chemical bonds are ionic and covalent bonds. An ionic bond essentially donates an electron to the other atom participating in the bond, while electrons in a covalent bond are shared equally between the atoms. The only pure covalent bonds occur between identical atoms. Usua...
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...
