Q

key points of covalent bonding

A
  • covalent bonding are formed when atoms of non-metals share pairs of electrons with each other.
  • each shared pair of electrons is a covalent bond
  • many substances containing covalent bonds consist of simple molecules but some have giant covalent structures.

Q

simple molecules

A
  • the atoms of non-metals generally tend to gain electrons to achieve stable electron structures.
  • when they react together, neither atom can give away electrons.
  • so they get the electronic structure of a noble gas by sharing electrons.
  • the atoms in the molecules are then held together by the shared pairs of electrons.
  • these are called covalent bonds.

Q

giant covalent structures

A
  • many substances containing covalent bonds consist of small molecules e.g H2o.
  • sometimes, covalent bonds can be very different.
  • they have giant structures where huge numbers of atoms are held together by a network of covalent bonds.
