Based on the above descriptions provided for silicon, I'm assuming that you want to know what silicon is categorized as, in the periodic table, since it posses some properties of metals and nonmetals it would be classified as a mettaloid or a semi metal.

Answer: The molecular formula will be
Explanation:
If percentage are given then we are taking total mass is 100 grams.
So, the mass of each element is equal to the percentage given.
Mass of H = 5.80 g
Mass of N = 20.16 g
Mass of O = 23.02 g
Mass of Cl = 51.02 g
Step 1 : convert given masses into moles.
Moles of H =
Moles of N =
Moles of O =
Moles of Cl =
Step 2 : For the mole ratio, divide each value of moles by the smallest number of moles calculated.
For H =
For N =
For O =
For Cl =
The ratio of H: N: O: Cl= 4: 1: 1: 1
Hence the empirical formula is
The empirical weight of = 4(1)+1(14)+ 1(16) + 1(35.5)= 69.5 g.
The molecular weight = 278 g/mole
Now we have to calculate the molecular formula.
The molecular formula will be=
