Covalent Bonding

Covalent bonding questions

HideShow resource information

1. Why do covalent bonds have high melting and boiling points?

  • There are strong covalent bonds between all atoms, that require a lot of heat energy to break.
  • There are strong ionic bonds between all atoms.
  • There is electrostatic attraction between all the atoms
  • There are many delocalised electrons.

2. What is the solubility of covalent substances?

  • The water molecules attract the negatively charges particles.
  • They are soluble.
  • They are not soluble, they have strong covalent bonds that are hard to break.
  • The water molecules attract the positively charges particles.

3. What is the conductivity of covalent substances?

  • They conduct because of the partial charges acting upon the individual atoms in the substance.
  • They do not conduct,the electrons are fixed in bonds and there are no free moving charged particles(EXCEPT GRAPHITE).
  • They conduct and sometimes don't when there are not enough charged particles in the substance.
  • They do conduct, they consist of free moving electrons.

4. What is the definition of covalent bonding?

  • An atom provides a lone pair of electron to another atom.
  • Shared pair of electrons between two atoms.
  • Electrostatic attraction between oppositely charges atoms.
  • Bonding between a metal and a none metal.

5. Which two elements form a giant covalent structure?

  • Carbon and silicon.
  • Phosphorus and silicon.
  • Fluorine and chlorine.
  • Boron and aluminium
