Answer : Option 2) Nonmetallic properties and ionization energy


Explanation : It is observed that the nonmetallic properties and the ionization energy when the elements in period 3 on the periodic table are considered in order from left to right.


Various changes are observed when we move from left to right in period 3 in the modern periodic table like the atomic number and charge on the nucleus increases , number of valence electrons increases , atomic radius decreases , first ionization energy increases , electro negativity increases except in Ar, elements found on the left are metals and elements on the right are non-metals, so non metallic character increases.

How does 0.5 m sucrose (molecular mass 342) solution compare to 0.5 m glucose (molecular mass 180) solution?
mash [69]

Answer : Both solutions contain 3.011 X 10^{23} molecules.

Explanation : The number of molecules of 0.5 M of sucrose is equal to the number of molecules in 0.5 M of glucose. Both solutions contain 3.011 x 10^{23} molecules.

Avogadro's Number is  N_{A} =  6.022 X 10^{23} which represents particles per mole and particles may be typically molecules, atoms, ions, electrons, etc.

Here, only molarity values are given; where molarity is a measurement of concentration in terms of moles of the solute per liter of solvent.

Since each substance has the same concentration, 0.5 M, each will have the same number of molecules present per liter of solution.

Addition of molar mass for individual substance is not needed. As if both are considered in 1 Liter they would have same moles which is 0.5.

We can calculate the number of molecules for each;

Number of molecules  = N_{A} X M;

∴  Number of molecules =  6.022 X 10^{23} X 0.5 mol/L X 1 L which will be  = 3.011 X 10^{23}

Thus, these solutions compare to each other in that they have not only the same concentration, but they will have the same number of solvated sugar molecules. But the mass of glucose dissolved will be less than the mass of sucrose.

How does the size of a nanoparticle compare with the size of an atom?
RSB [31]
A nanoparticle is larger than an atom. A nanoparticle is usually made from a few hundred atoms. These  particles range from 1 nanometers to 100 nanometers. On the other hand an atom ranges from 0.1 nanometers to 105 nanometers. Using the sizes above, one can clearly see and understand that an atom is smaller.
