ionic bond for example MgCl2 the diagram will be like [Mg]^2+ 2[Cl]- (note that you need to draw the valence electrons of the anion) 2011-06-23 18:40:55 补充： covalent bond for example O2 You need to draw the O atoms together that is their outermost electron shell ov...
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...
The type of bond formed between atoms can be single, double, or triple.What is a Covalent Bond? An atom is comprised of electrons, neutrons, and protons. It acts as a building block of elements in chemistry. An element is a substance that cannot be altered into simpler substances through...

In anionic bond, one atom essentially donates an electron to stabilize the other atom. In other words, the electron spends most of its time close to thebonded atom. Atoms that participate in an ionic bond have different electronegativity values from each other. A polarbondis formed by the att...
A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. A covalent bond is a chemical bond that involves the repulsion of like charges between atoms. A covalent bond is a chemical bond that involves the transfer of electron pairs between atoms. A covalent...
Describe how a covalent bond forms.You have already seen examples of substances that contain covalent bonds. One substance mentioned in Chapter 3 “Ionic Bonding and Simple Ionic Compounds” was water (H2O). You can tell from its formula that it is not an ionic compound; it is not composed...
Bond Length In Section 4.1 “Covalent Bonds”, we stated that the covalent bond in the hydrogen molecule (H2) has a certain length (about 7.4 × 10−11 m). Other covalent bonds also have known bond lengths, which are dependent on both the identities of the atoms in the bond and ...
that the main differences between covalent and hydrogen bonds are: 1. A covalent bond is formed by sharing of electron pairs between same or distinct atoms. Sharing allows each atom involved to attain stability. A hydrogen bond occurs under specific condition, where a hydrogen atom which i...
Exceptions to the Octet Rule 8.2 Exceptions to the Octet Rule Exceptions to the Octet Rule (Oh, nooo!!!) Sometimes there will exist molecules with atoms that have fewer or more than an octet of valence electrons. Exceptions to the Octet Rule 8.2 Exceptions to the Octet Rule NO2 is produce...
