This attraction pulls the atoms together and the electrons are shared by both atoms. The atoms bond because there is a strong enough attraction in both directions and room for the electrons in the ...

Changes of state: interactive activity - AQA Learn about changes of state from melting, evaporating and boiling with this interactive activity designed for the GCSE AQA chemistry specification.

neutrons, electrons, and energy levels in atoms and their location in the periodic table. Students will also explore covalent and ionic bonding.

Energy is required to break a covalent bond between two atoms ... The opposite is true if we want to make new bonds. Energy is released when new chemical bonds are formed, so bond making is ...

and a small difference indicating a non-polar covalent bond (e.g., C-C bond). Electronegativity is crucial for explaining various aspects, ranging from the energy of chemical bonds to the ...
