The first ionisation energy is the energy required to remove one electron from an atom. Down a group, there are more electron shells surrounding the nucleus, which results in a greater shielding from the ...
Le Chatelier's principle states that the position of equilibrium will shift to oppose the change of conditions to a system. For example, if the temperature is increased the position of equilibrium will sh...
A giant macromolecular covalent structure with a high melting point and covalent intramolecular bonds between all atoms.
The oxidation state of O is -2, and +1 for H, so as HClO is neutral overall, the oxidation state of Cl in HClO is +1.
As you go down the group:shielding increases as electron numbers increase, this means that the distance between the nucleus and outer electron is further and attraction is weaker between the positive nucl...
