<span>What is the relationship between the atomic numbers and ionic radii of the elements in group 1? What is the relationship between atomic numbers and first ionization energies?
</span>Answer:
When we see down the groups, the atomic number and the atomic radius both increase.Extra shells are produced which increase the size of the higher atoms.
If we go across the periods, the atomic radius decreases due to the higher nuclear charge in the atoms. This pulls the electrons more closer to the nucleus.
Answer:
820.864 g
Explanation:
1) The atomic mass of sulfur (found from the periodic table) is 32.065 amu. Use this mass to find the molar mass of Sulfur. Sulfur is S8 so the molar mass of sulfur is:
8 × 32.065 = 256.52 g/mol
2) To find the mass use the formula:
m = n × M where <em>m</em><em> </em>is the mass, <em>n</em><em> </em>is the number of moles, and <em>M</em><em> </em>is the molar mass.
