Electronegativity is the measure of how strongly an atom attracts a bonding pair of electrons to itself. As group 7 is descended, the electronegativity decreases. This is because the size of the halogen atom...

With these sort of questions, it's important to firstly think about what type of bonds make up the structure of the element. For this example, they both have metallic bonds which hold the structures together...

In order to answer this question we should first break it down into simpler parts. Using the law of indices we can start this process. Using the law above we can break down the components of the original que...

Absorption spectra from distant galaxies consist of bands of coloured light crossed with black lines. The wavelengths of these black lines are shifted towards the red end of the spectrum when compared with l...

Both of these compounds are made purely of carbon. The differences come in the way in which the atoms are bonded together and the properties that this creates.In diamond, each atom is covalently bonded to fo...
