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...
Ionic compounds form when the atoms of a metal combine with the atoms of a non - metal
Ionic compounds form when the atoms of a metal combine with the atoms of a non - metal
1.34 understand that ionic compounds have high melting and boiling points because of strong electrostatic forces between oppositely charged ions1.35 understand the relationship between ionic charge and the melting point and boiling point of an ionic compound1.36 describe an ionic crystal as a giant three-dimensional lattice structure held together...
