In the space provided below, draw electron-dot diagrams for the following molecules: hydrogen (H2), ammonia (NH3), and methane (CH4). Remember that the dots represent the valence electrons. Make sure that each atom in the molecules have 8 valence electrons, except hydrogen, which has only 2.

Respuesta :

Answer :

The steps involved in the electron-dot structure of given molecule are :

Step 1 : First we have to determine the total number of valence electron in a molecule.

Step 2 : Draw the skeleton of the molecule.

Step 3 : Placing a bonding pair of electrons between the atoms to form the chemical bonds.

Step 4 : The rest of the electrons are used as a lone pair for central or terminal atoms to achieve an octet to finish the electron-dot structure.

All the electron-dot diagram of given molecule is shown below.
