What is the difference between an ionic and a covalent bond?

A chemical bond joins two atoms together.
In covalent bonding, atoms are joined by sharing electrons. For example, water (H2O) is created through two OH bonds in each of which, Oxygen and ...

Explain why ionic compounds such as potassium sulfide have high boiling points and conduct electricity when dissolved in water?

Such compounds have high boiling points because bonds between the atoms are strong. The boiling point largely depends on electronegativity difference between the atoms - as this difference is greater, so ...

Explain how the differences in structure between Diamond and Graphite give rise to their different properties

Carbon has 4 electrons in its outer shell, so to fill its outer shell (which can hold up to 8 electrons) and be stable, it wants another 4 electrons. It can do this by sharing its 4 electrons in 4 strong ...

How does increasing the temperature affect the yield of products of a reaction at equilibrium, where the forward reaction is exothermic?

The position of equilibrium changes after the temperature increases according to Le Chatelier's principle, which states that if a change is applied to a system in equilibrium, then the position of equilib...

Draw a mechanism for electrophilic addition?

We can take the electrophilic addition of bromine to ethene as an example. The double bond in ethene acts as an area of high electron density causing an induced dipole on the Br2 molecule, givi...
