The reactivity of an element is significantly influenced by the number of electrons in its group shell. Elements with a nearly complete group shell tend to be more reactive as they seek to either gain or lose electrons to achieve a stable electronic configuration. This is why metals, which often have one or two electrons in their group shell, readily donate them, while nonmetals, with five or six electrons in their group shell, tend to gain electrons to complete their shell.

The primary advantage of PDC drill bits lies in their ability to maintain a consistent cutting action, even under high pressure and temperature conditions. Unlike conventional roller cone bits, PDC bits do not wear out or dull easily, ensuring continuous drilling without the need for frequent replacements. Moreover, their design enables them to handle variable rock formations, making them versatile tools for various drilling applications.
