Based on the ionization energy levels of element 3, one can tell that the element is Magnesium. Magnesium has an atomic number of 12 so in a neutral atom, that means that there are 12 protons and 12 electrons. So based on the electrons, we can write the electronic configuration as:

Answer:
from the pic:
since molar mass is 118.084 g/mol;
It is an aldehyde with structure ( second pic )
Aromatic compound has continuous cyclic structure with( 4n+2)π electrons (Huckels rule), where n = 0,1,2…
Here number of pi electron are 6, where 4 from two double bond and 2 from nitrogen non-bonding electrons, hence it has total 6 pi electrons, therefore
6= ( 4n+2)π
4 = 4n
n =1
Hence it is an aromatic compound
