It depends on the number of valence electrons required to make octet or duplet( in case of H)
. For example, Nitrogen(atomic number = 7) has electronic configuration(2,5) which means nitrogen has 5 valence electrons and requires 3 more electrons to complete its octet. After gaining 3 electrons from atoms of an element with less electronegativity than N, it forms nitride ion ().
Hope this helps.

Answer:
0.0630
Explanation:
The molar mass of urea = 60 g/mol
we all know that:
Then; the number of moles of urea
=
= 0.0667 mol
Similarly; the number of moles of methanol
=
= 0.9988 mol
The total number of moles = (0.0667 + 0.9988) mol
= 1.0655 mol
Finally,the mole fraction of urea =
=
= 0.0630
