Answer:
White being the color and coming in small grains.
Explanation:
Physical properties are something you can clearly see about the object.
<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.
Hello!
* First Step: to know Avogrado's Law
We know that by the Law of Avogrado, for each mole of substance we have 6.02*10²³ atoms, if:
** Second Step: to know the molar mass of the solute
The molar mass of of magnesium = 24.30 g/mol
*** Third step: make the ratio mass / mol with atoms
1 mol we have 6.02*10²³ atoms
1 mole of Mg we have 24.30 g
Then we have:
24.30 g ------------- 6.02*10²³ atoms
x ----------------------- 6.98*10^24 atoms
multiply cross
I Hope this helps, greetings ... DexteR! =)
Answer:
When ionic solutes are dissolved in water, the molecules of water pull the ions of the crystal apart and the electrostatic forces are cut off. Further the ions are surrounded by the water molecules which act as a barrier around the ions and prevent the recombination of ions.
