Chemistry- bonding
- when chemical reactions take place, chemical bonds are made
- this happens when an atom either shares or gains electrons
- this happens when an atom either shares or gains electrons
- ionic bonding concept
- gaining elecctrons
- if you gain you become negative
- if you loose you become positive
- if you loose you become positive
- if you gain you become negative
- gaining elecctrons
- covalent bonding
- strong covalent bonds within the molecules
- weak forces of attraction between the molecule
- sharing electrons
- sharing electrons
- weak forces of attraction between the molecule
- strong covalent bonds within the molecules
- giant covalent structures
- diamond
- high melting and boiling points
- diamonds a form of carbon that has a giant, rigid covalent structure, each carbons make four bonds.
- large number of covalent bonds resluts in high boiling/melting points- makes it hard
- large number of covalent bonds resluts in high boiling/melting points- makes it hard
- diamonds a form of carbon that has a giant, rigid covalent structure, each carbons make four bonds.
- high melting and boiling points
- strong covalent bonds between the two carbon atoms
- diamond
- Graphite
- covalent bonds between 2 carbons
- weak intermolecular force
- graphite only makes three bonds
- layers can easily slide over eachother
- layers can easily slide over eachother
- graphite only makes three bonds
- weak intermolecular force
- covalent bonds between 2 carbons
- Silicon Dioxide
- strong covalent bonds
- salt
- very high melting point
- very high melting point
- salt
- strong covalent bonds
- Afullerene
- carbon atoms form fullerenes.
- hexagonal rings
- covalent bonds
- no giant covalent structures
- simple molecules
- simple molecules
- no giant covalent structures
- covalent bonds
- hexagonal rings
- carbon atoms form fullerenes.
- Giant ionic substances
- mixture of positive and negative charged ions
- high melting points
- lot amount of energy to break it
- must be dissolved in water for it to conduct
- must be dissolved in water for it to conduct
- lot amount of energy to break it
- high melting points
- mixture of positive and negative charged ions
- metals
- giant structure
- delocalised electrons surround positive ions
- Hold structure allow the atoms to slide over eachother
- metals can be shaped or bent
- metals can be shaped or bent
- Hold structure allow the atoms to slide over eachother
- delocalised electrons surround positive ions
- giant structure
