Bonds is something that retains and holds on together with one another. There are three major chemical bonds and they are‚ Ionic‚ Covalent‚ and Hydrogen bonds. An example of a covalent bond would be SCl^2 which is Sulfur dichloride. SCl^2 is a covalent bond because since they are close to each other in valence electrons‚ they have almost full outer shells so they share electrons with one another. A good example is table salt NaCl‚ because they are on opposite sides of the periodic table therefore

molecule with covalent bond o Formula unit with ionic bond * Molecules: formed by covalent bonds * Lattice energy is the energy released in the formation of an ionic compound. DEFINITION: The formation of an IONIC BOND is the result of the transfer of one or more electrons from a metal onto a non-metal. Characteristics of both bonds: * Occur between 2 atoms * Composed of 2 electrons * Have both ionic and covalent characteristics * Together = 100% * Both bonds are measured on

How do ionic bonds form? Transferring the electron forms an ionic bond. After transferring the electron‚ the two atoms become ion n will attract together because they have the opposite charges. Then an ionic bond is formed. How do covalent bonds form? A covalent bond is for sharing of electrons. I remember it like co-existing electrons to share (Eg H20). It is usually between two non-metals. Which compound‚ sugar or salt‚ is a better conductor of electricity? Explain your answer. Salt

molecular oxides on the right. Sodium peroxide‚ magnesium oxide and aluminum oxide are metallic oxide which have high melting and boiling point compared to other period 3 oxide. This is due to their giant ionic structure and the strong ionic bond. Strong ionic bond in the molecule need more energy to overcome it. Therefore‚ the more energy required‚ the higher the melting and boiling point. Aluminum oxide will have higher melting and boiling point than magnesium oxide because Al3+ ions having

my household: Barry Bonds. To use those to words was worse than any other expletive in the English language. As I grew older‚ I was astonished to learn that other people did not treat that name with the same infamy that I was taught to use. Some people‚ I learned‚ even considered Bonds to be the greatest player of all time. I was astounded. How could this man‚ whom I had been conditioned to avoid even saying the name of‚ be treated with so much reverence? Barry Bonds‚ for the non-sports
