Esters are organic compounds that contain an ester functional group. An ester functional group is a COO group. 3D version of the ester methyl ethanoate Esters are named from the alcohols and carboxylic acids they were created from : (Eg. methanol + ethanoic acid => methyl ethanoate + water) Ingredients: Sulfuric acid Ethanol...

Covalent bonds form when electrons are shared between nuclei Atoms which can form two or more covalent bonds can bond with other similar atoms or themselves and form covalent lattices. Carbon in the form of diamond is a good example, as is silicon dioxide in the form of quartz. A valuable lattice Activity. Diamond - clos...
Look at the images of ice and diamond. In some senses you might say the two substances are similar. Both substances are solid, transparent and crystalline. In terms of bonding, they have similarities too : In ice, atoms of oxygen are held to hydrogen atoms by covalent bonds. In diamond atoms of carbon ar...
When non-metal atoms bond to other non-metal atoms they share electrons to form covalent bonds.
When non-metal atoms bond to other non-metal atoms they share electrons to form covalent bonds. 1.45 Activity. Opposites attract Students should: 1.44 know that a covalent bond is formed between atoms by the sharing of a pair ofelectrons1.45 understand covalent bonds in terms of electrostatic attractions Play the video t...
When non-metal atoms bond to other non-metal atoms they share electrons to form covalent bonds.
1.38 Activity. Know your ions. Students should: 1.38 know the charges of common ions listed You will have noted from the video that metal atoms tend to lose the electrons in their outermost electrons and form positive ions. The charge of the ion formed is equal to the number of electrons lost. Non metal atoms gain el...
1.39 Activity. Finding formulae Students should: 1.39 write formulae for compounds formed between the ions listed Watch the video closely pausing where instructed. Use the information given to work out the correct formulae for the following compounds: Name of compoundFormula lithium nitridepotassium oxidezinc oxidesilver chlorideLi3N&nb...
