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...
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...

Covalent and ionic bonds are two types of intramolecular forces, meaning they are the bonds formed by the valence electrons of different atoms to hold the atoms of a molecule together.Answer and Explanation: Covalent bonds arise between atoms that have smaller or no electronegativity differences ...

3.1 Covalent and Ionic Bonds Two major types of chemical bonds exist (i.e. covalent and ionic). The covalent bond is defined as a region of relatively high electron density between nuclei that arises, at least partly, from the sharing of electrons and produces an attractive force and characte...
Covalent and ionic bonds are two types of chemical bonds that may form between elements. Covalent bonds are generally stronger than ionic bonds. Both are common in compounds that we encounter every day. Answer and Explanation:1 An ionic bond i...
IONIC BONDING Some elements tend to gain electron(s) readily while others tend to lose electron(s) (low I.E.) When an active element (metal) reacts with an active non-metal), electrons are transferred from the metal to the non-metal. Atoms of the non-metal become anions while the met...
