8 0
Group 2A of the Periodic table contains the Alkaline Earth metals. Those elements are Beryllium ( Be ), Magnesium ( Mg ), Calcium ( Ca ), Strontium ( Sr ), Barium ( Ba ) and Radium ( Ra ). Beryllium is the lightest member of the group 2A. Ionic radius increases moving down the group and decreases from left to right across the period of elements. In the group 2A, the ionic radius increases from Beryllium ( 59 pm - picometers ) to Radium ( 163 pm ). Answer: Beryllium has the lowest ionic radius.

What is the oxidation state of cr in CrPO4 and Cr3(PO4)2?
soldi70 [24.7K]

Answer:

Explanation:

Oxidation state of Cr in CrPO₄

As a general rule, the algebraic sum of all the oxidation numbers of all atoms in a neutral compound is zero.

The compound above is in its neutral state and we sum all the oxidation numbers and equate to zero:

The oxidation number of P is -2

                                           O is -2

Let the oxidation number of Cr be x:

                              x + (-2) + 4(-2) = 0

                              x -2-8 = 0

                               x -10 = 0

                                x = +10

For Cr in Cr₃(PO₄)₂

         Using the same rule:

        2(x) + 2[-2 + 4(-2)] = 0

           2x + 2(-2-8) = 0

            2x -20 = 0

                x = +10

The density of water at 4 degrees Celsius is 1.000 g/mg is it chemical or physical property?
Kaylis [27]

Answer:

Physical Property

Explanation:

Density, mass, volume, color, melting and boiling points, etc. are all physical properties. No matter what changes, the chemical makeup stays the same.

Flamability, acidity, toxicity, etc. are chemical properties, because they chemically change the makeup of the object/thing.
