Final answer:
The root bridge in a network is determined through an election process part of the Spanning Tree Protocol, where the switch with the lowest identifier becomes the root. Without specific Bridge IDs or priorities, the switch with the smallest MAC address is typically elected.
Step-by-step explanation:
The question seems to be conflating concepts from two different fields: networking and chemistry. However, when referring to the election of a root bridge in a network, it comes from the realm of Computers and Technology. The root bridge election is part of the Spanning Tree Protocol (STP) which is used to prevent loops in network topologies. In this protocol, switches participate in an election process based on unique identifiers and priority values, with the lowest value becoming the root bridge.
Without specific details such as Bridge IDs or priority numbers of the switches involved, it's impossible to provide the exact answer in 200 words. The electing switch will usually have the lowest bridge identifier, which includes a combination of the switch's priority and MAC address. In the absence of manually configured priorities, the switch with the smallest MAC address would become the root bridge after the election process is complete.
