As you go across the period from sodium to chlorine, the number of protons in the nucleus increase.As protons are positively charged, they attract the outer electrons; as the number of protons increase, t...

Firstly, how many electrons does nitrogen have in its outer shell?... Nitrogen is in group 5, so 5.How many more electrons does nitrogen need to give it a full outer shell?... 8 electrons provide a full o...

You would add tollen's reagent to both samples. The butanal would form a silver mirror, whereas, butan-2-one would remain unchanged. This is due to the fact that an aldehyde can be oxidised to a carboxyli...

N₂(g)+3H₂(g) ⇋ 2NH₃(g) ΔH=-92kJmol^-1 (equation for question above)
According to Le Chatelier's principle, a system in dynamic equilibrium will shift th...

Bromine exists as Br₂, and since both bromine atoms are identical - their electronegativities identical, - the electron density is distributed evenly across the molecule (it is non-polar, the a...
