Answer 1

Answer:

electrons :- one of the three types of particles that form all atoms. Electrons have a negative electric charge !

Valence electrons are the outermost electrons and are therefore at the highest energy level. Because they are the outermost energy levels, they are available to participate in chemical bonding, either ionic or covalent. ... In summary, valence electrons determine the bonding patterns of atoms.

The definition of configuration is the way parts are arranged to work together. ... When you try to set up your computer hardware and software to work the way you want such as adding a wireless mouse and keyboard, this is an example of configuration.
