As we travel along the period the nuclear charge increases, this increases the grip the nuclei of the atom has on the electrons. As they are on the same period they experience almost the exactly the same ...
Neither iodine or chlorine have permanent dipoles because there is no difference in electronegativity between the atoms, so there are no permanent dipole : permanent dipole interactions. There are also no...
Hydrogen bonds are the strongest, which are possible only between H and F, O or N because of the difference in electronegativity; then, permanent dipole-permanent dipole interactions come second as they f...
Using the AQA specimen data sheet we see that the RAMs of the following elements areCa = 40.1H = 1.0C = 12.0O = 16.0Therefore the total mass for one mole isCa + 2x(H + C + O+O+O)= 40.1 + 2x(1+12+16+16+16)...
The main factor influencing a given compound's state is the strength of intermolecular forces - those need to be larger than the thermal energy for a compound to be solid/liquid. For CO2 the only type of ...
