答:共价键和离子键的强度较高,由这两种键合形成的材料通常具有较高的硬度,如金刚石。由金属键结合构成的金属材料通常也具有一定的硬度,其硬度主要受金属晶体结构的影响,形成固溶体或合金时可显著提高其硬度。Answer: Strength of covalent bond and ionic bond are high, materials formed with these two bonds usua...
What is the difference between an ionic bond and a covalent bond?相关知识点: 试题来源: 解析 An ionic bond is formed when electrons are transferred from one aton to another to form negative and positive ions.A colvalent bond is formed when electrons are shared between two atoms....
What is the difference in macroscopic properties between covalent and ionic bonds? What is the state fish of Minnesota? What is the state fish of Connecticut? What is the state fish of South Dakota? Why is SO_2 non polar whereas SO_3 is polar?
Other characteristics of most covalent compounds are their inability to dissolve in and their inability to conduct electricity in water. Lastly, covalent compounds tend to be flammable compared with ionic compounds. This flammability occurs because many covalent bonds tend to be comprised ofand hydrogen...
What H+ ions of an acid and the OH- ions of a base means. What is the difference in macroscopic properties between covalent and ionic bonds? What are the products of the reaction between the two compounds NaOH(aq) and HCl(aq)?
Two notable exceptions are hydrogen and helium, both of which need two to make a closed shell. The affinity for atoms to achieve stability by gaining or losing valence electrons provides a foundation for two types of chemical bonds: the ionic bond and the covalent bond. Ionic bonds are ...
If it is 1.7 the bond will be half covalent and half ionic. Types就是金非离,非非共。。典型金属和典型非金属的化合物为离子键,两性金属与非金属间视具体元素而定,非金属间为共价键。 Ionic bonds are between metals and non-metals. Covalent bonds are between non-metals and non-metals2.上传了氧...
What is the difference between how covalent bonds and ionic bonds are formed? Provide examples of each. How are covalent bonds and ionic bonds similar and different? 1. How are ionic and covalent bonding similar? How are they different? How they...
Types of Bonds: There are two main types of strong bonds that occur between molecules, covalent and ionic. Ionic bonds occur when one atom donates electrons to another. Covalent bonds occur when two atoms share electrons. Answer and Explanation:1 ...
Valency can apply to multiple types of bonds, including covalent, ionic, and metallic bonds, whereas covalency is solely concerned with covalent bonds. 10 Valency is often determined by the number of electrons in the outermost shell of an atom that can be involved in bonding. Covalency refers ...
