Handedness is a human behavior where multiple factors work on. It is a complex trait. Basically it based on the comfort and skill. One may be comfortable with right hand where others are comfortable with right. Genetic influence is very less in this case, though very little is known about the biological basis. Hand preference tend to be consistent through out the life and begin to develop during the prenatal stage. Recent studies show that multiple genes can be responsible for the handedness.
<span>We know that electrons are occupied on a cloud surrounding
the nucleus. So which means that the bigger the electron cloud, the bigger the
number of electrons. So in this case, since Na shrank so it lost some
electrons. And since Cl+ grew in size of the electron cloud so electron was
added to it.</span>
