Electrons are the part of an atom involved in chemical reactions, as they form bonds between atoms. Protons and neutrons, located in the nucleus, do not generally participate in these processes. Understanding the role of electrons is essential for grasping how atoms interact in chemical reactions. ;
A device with a current of 15.0 A for 30 seconds results in approximately 2.81 billion billion electrons flowing through it. This is calculated using the relationship between charge, current, and time. The charge of a single electron is used to determine the total number of electrons passing through.
