Write the symbol for sulfur. What is the atomic number of it in the periodic tab

Question

Write the symbol for sulfur. What is the atomic number of it in the periodic table? How many protons and electrons are there in the atom of sulfur? Give the highest possible and lowest possible oxidation state for sulfur. Determine it's molar mass. Na2SO4 . Determine the molar mass for this compound and the oxidation state of sulfur in it. Write the oxide formula of sulfur for the corresponding oxidation state. Determine whether this oxide will react with HC1, NaOH, and write the corresponding reaction equations. Name these compounds: K2SO4, NiS, NaNCO2 .

Explanation / Answer

atomic no. = 16

symbol = S

protons-16
neutrons-16
electrons-16

highest oxid state = +6

molar mass= 32.07

2)

molar mass=

oxid state= +6

SO 2-

it will react with both forming h2so4 and na2so4

3)

potassium sulphate

nickel sulfide

sodium nitrate
