P has five electrons, three available to share. Since Cl has seven valence electrons, it can take on one more to accomplish an octet. In PCl3, P’s three valence electrons are evenly distributed among the three chlorine atoms. Whereas, in PCl5 there will be two electrons left over, which is why it is an exception to the octet rule.

Explanation:

Gallium, scandium, and germanium were later discovered to coincide with his predictions. In addition to the fact that Mendeleev's table was published before Meyers, his work was more extensive, predicting the existence of other elements not known at the time.

A stream of negatively charged particles is called:
AlladinOne [14]
Cathode rays are a stream of negatively charged particles or electrons in vacuum tubes. They were first seen by Johann Hittorf in 1869. They are named since they are emitted by electrode or cathode. In order to release the electrons, the electrons should first be detached from the atoms of the cathode.
