Answer:

The question was to be what is metal in modern periodic table?. Thank for understanding.

Now we come to business:

Metal in modern periodic table:is all the elements to the left of the line.

Explanation:

  • if you look at the modern periodic table diagram you will see a stair-stepped line starting at Boron(B),atomic number 5,and going all the way down to Polonium(Po), atomic number 84.Except for Germanium(Ge)and Antimony(Sb),all the elements to the left of the line can be classified as metals.

The fifth element in group 7 in astatine would you expect it to be gas, liquid, or solid? why?
Ymorist [56]

Answer:

solid

Explanation:

Melting and boiling points of Group 7 elements State at room temperature Room temperature is usually taken as being 25°C. At this temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine and astatine are solids. There is therefore a trend in state from gas to liquid to solid as you go down the group.

What is the molarity of a solution in which 7.1 g of sodium sulfate is dissolved in enough water to make 100. mL of solution?
Sidana [21]

Answer:

0.50 M

Explanation:

Given data

  • Mass of sodium sulfate (solute): 7.1 g
  • Volume of solution: 100 mL

Step 1: Calculate the moles of the solute

The molar mass of sodium sulfate is 142.04 g/mol. The moles corresponding to 7.1 grams of sodium sulfate are:

7.1g \times \frac{1mol}{142.02g} = 0.050mol

Step 2: Convert the volume of solution to liters

We will use the relation 1 L = 1000 mL.

100mL \times \frac{1L}{1000mL} =0.100L

Step 3: Calculate the molarity of the solution

M = \frac{moles\ of\ solute }{liters\ of\ solution} = \frac{0.050mol}{0.100L} =0.50 M
