If you follow the octet rule, you know that an element must have 8 outside (or valence) electrons to be energetically favorable.
In CCl4, the carbon molecule forms four bonds; one for each chlorine atom. Each bond contains 2 electrons, so it is satisfied.
In PCl3, Phosphorous forms only 3 bonds with chlorine, which means in order to have 8 valence electrons, it also has a lone pair of electrons, not bonded with chlorine.
Now, in CCl4, picture the shape of the molecule like a plus sign, with the carbon in the middle and the chlorine at the four ends. It is symmetrical, and therefore is nonpolar.
In PCl3, the lone pair electrons <em>push</em>, so to speak, the 3 chlorine atoms away, making a T-shaped molecule. Since the chlorine is more electronegative than carbon, the molecule is unbalenced, making it polar.
Answer is C, continents were once all joined together
Answer:yes because due to ionization atom makes chemical bonds with other atoms, which makes change in the properties of atoms
Explanation:
They are not allike as na atom has 11 elctrons and Na ion has 10 electons. <span>They both have the same nucleus (same number of protons and neutrons). The only difference is that the ion has one less electron than the atom (in this case).</span>
