V _ionic or compound
3241004551 [841]
Ionic compounds are formed by the bonding of non-metals to metals. Because inonic bonds involve electon transfer, the result is a mixture of ions; positive and negative, following the laws of electrostatics, like charges attract. These ions then form a giant structure (lattice) of ionic bonds and it is because of this that ionic compounds are solids (unless dissolved in water) and have extremely high melting and boling temparatures. In additions, beucase of the fixed placement of ions (charged particles) in a lattice, in the solid state ionic compounds don't conduct electricity very well but if dissolved in water (aqueous solution) the ions are free to move and carry a current.

How many atoms are present in 4.0 mol of sodium
gladu [14]
Avogadro's constant is the number of atoms of carbon-12 in 12g of
carbon-12.
atoms present equals avogadro's constant times number of moles for that substance. Type of substance does not change the number of atoms if you are given the quantity of moles, therefore the fact that it is sodium does not change the value.
<span>atoms present equals avogadro's constant times number of moles
</span>=6.023x10^23 x 4.0
=2.4x10^24
