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....
Which of the following best describes an ionic bond? (a) An ionic bond involves two metals that exchange electrons. (b) An ionic bond involves two nonmetals that share electrons. (c) An ionic bond involves a metal that shares electrons with a no...
An ionic bond is associated with which of the following? The transfer of electrons from a metal to a nonmetal The sharing of electrons between two nonmetals Both metals and nonmetals gain electrons Interactions between nuclei Not the question you’re ...
Explore the Materials——From an Atom to a Device(走进材料——从原子到器件)(北京航空航天大学) 大学MOOC慕课 客观题答案 The basic unit of materials is___, which can bond directly together to form materials, or convert into ions, or assemble into molecules. A. nucleus B. electron C. proton...
How to Tell if a Bond Is Ionic or Covalent? An ionic bond forms between a nonmetal and a metal in which the nonmetal attracts the electron from the other atom. Ionic bonds are high in polarity, have no definite shape and have high melting and boiling points. At room temperature, an ion...

Give an example of a compound that has an ionic bond and explain how the ionic bond was formed. Which conditions suggest that a bond will be ionic? What attracts the atoms in an ionic bond? What makes a covalent bond? Is SO2 an ionic or covalent bond?
Hi, and welcome to this video on ionic bonding- one of the three primary ways in which atoms combine to form bonds. Formation of Ionic Bonds Let’s start by considering why two atoms bond in the first place. Alone, their aggregate energy is here. But when they get close together, their...
