14g of sodium chloride was dissolved in 250cm3 of distilled water. Calculate the concentration of thesresulting solution in mol/dm3

chemists can use the electron cloud model to assign electrons to different atomic orbitals. atomic orbitals also explain the patterns in the periodic table

explanation:

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
