C2 bonding Flashcards
where does ionic boding occur
metal and non metal
where does covalent bonding occur
non metal and non metal
where does metallic bonding occur
metal and metal
in ionic bonds particles are…
oppositely charged ions
in covalent bonds particles are…
atoms that share pairs of electrons
in metallic bonds particles are…
atoms that share delocalised electrons
what states do ionic, covalent and metallic bonding have
solid,gases/liquid,solids
what melting points do ionic, covalent and metallic bonding have
high, low, high
how are ions formed
when an atom loses an electron positive ions are formed and vice versa
what are the differences between inter and intra molecular forces
inter are between molecules intra is inside molecules
name some properties of ionic bonds
-giant ionic lattice where there are strong electrostatic forces of attraction in all directions
-high melting points and boiling points because a lot of energy is required to break the strong bonds
-when melted or dissolved in water ionic compounds conduct electricity because the ions are free to move and carry current but not as a solid as the electrons are fixed in place
what are some features of polymers
-very large molecules
-strong covalent bonds
-solid at room temperature
what are some features of covalent bonds
-solid with high melting points
-strong covalent bonds
what are properties of metals
-metallic bonds
-high melting and boiling points
-can be bent and shaped because metals can slide over each other
what are properties of metals
-metallic bonds
