[Ne] 3s2 3p5 ----------------
CI does not exist. Cl (with a lowercase L) is the element chlorine
"Ci" isn't a symbol on the periodic table.
There is no element with the symbol Ci. There is an element with the symbol Cl (capital C, lowercase L), chlorine, which is a non-metal.
Chlorine=CI =)
A Configuration Item (CI) is any component that needs to be managed in order to deliver an IT service. Information about each CI is recorded in a configuration record within the Configuration Management System and is maintained throughout its lifecycle by Configuration Management. CIs are under the control of Change Management. CIs typically include IT services, hardware, software, buildings, people and formal documentation such as process documentation and SLAs.
