Chromium (Cr): 2, 8, 8, 6
Copper (Cu): 2, 8, 8, 11
Chromium+2 (Cr+2): 2, 8, 8, 4 (if the ion retains a positive charge then the amount of electrons will decrease)
Copper+2 (Cu+2): 2, 8, 8, 9
Manganese+2 (Mn+2): 2, 8, 8, 5
The given question is incomplete, the complete question is:
Which of these can be considered a system? Check all that apply.
O a computer
O a car
O a bicycle pedal
O a pencil
O a coffeemaker

Explanation:
An array of rules or the group of things, which function together to attain a specific goal is termed as a system.
