The elements of the "Noble" gases group is nonreactive. The reason for this is that noble gases are always or most of the time at room temperature.<span />
Scientists make hypothesis in order to make an educated guess on the outcome of the experiment.
Answer:
To gain stability
Explanation:
If the outermost shell is not completely filled with electrons, the element has one of the three options: gaining electrons, losing electrons or sharing electrons. By gaining or losing electrons, ionic compounds are produced. Sharing of electrons results in the formation of covalent compounds.
In ionic bond there is the formation of ions due to transfer of electrons from one atom<span> to </span>the other. Normally, at this link, there is an element that tends to yield electrons (metal-cation), and one that tends to receive electrons (not metal-anion).
Note: the Ionic bond is the only in the transfer of electrons<span>.</span>
You should use the joules (J) unit of measurement.
