The orbital is the probable location of the electron of an atom.
Always remember the difference between Bohr and wave-mechanical model in terms of electrons!
Your questions answer is Electron!
But you should also know Bohr said electrons are in orbitals in a fixed proportion, but modern wave mechanical disagrees with this and said electrons are arranged in a very complex random proportion in a region called orbital!
Hope this helped
have a smiley day (:
Answer:
Electronegativity increases as you move across the periodic table from left to right.
Explanation:
The correct answer is
<span>3. Organic Chemistry.....</span>
The solution is non-ideal for NaCl soln so ΔH3<span> is greater than the sum of ΔH</span>1<span> and ΔH</span>2. this means the forces of attraction between like molecules is greater than the forces of attraction between unlike molecules. <span>NaCl (table salt) dissolves readily in water. In solid NaCl, the positive sodium ions are attracted to the negative chloride ions. The same is true of the solvent, water; the partially positive hydrogen atoms are attracted to the partially negative oxygen atoms. While NaCl dissolves in water, the positive sodium cations and chloride anions are being stabilized by the water molecule electric dipoles. Thus, the intermolecular bonds between NaCl are broken and the salt is dissolved.</span>
One mole of CuSO4 contains one mole of Cu2+.
One mole of any substance contains Avogadro's number of ions.
Therefore, number of ions of Cu2+ can be calculated as follows:
number of ions = number of moles * Avogadro's number
number of ions = 1 * 6.02 * 10^23 = 6.02 * 10^23 ions
