As we go from Li to F, atomic radius of the atoms will DECREASE. This is due to increased nuclear charge (number of protons within each atom). Although the number of electrons also increases, each addi...

Ionisation energy is the energy required to remove the most loosely bound (furthest out) electron from an atom, in the gaseous state.
As you move down a group in the periodic table, the number of...

Several d-metal complexes show colour. This is because their d-orbitals are not degerate in energy levels. Instead the d-orbitals split, some having higher energy than average and some lower than avera...

Bonding is when two atoms join together; this happens through movements of electrons to help create a full outer shell of electrons. Ionic bonding is when this takes place between a metal and non metal...

A greenhouse gas is one which absorbs infrared radiation from the Earth and re-radiates it, increasing the surface temperature of the Earth. Normally these molecules are non-symmetrical such as triflur...
