Answer:
Neon: 0
Oxide: -2
Copper: 2
Tin: 0
Step-by-step explanation: To solve you must add/subtract the numbers to get the charge, for example if its -30 charge from electrons and 10 charge from protons, -30 + 10 = -20 therefore the charge is -20
Make a ratio, then cross multiply.
4/30=x/48
30x=4x48
30x=192
x=6.4
Your answer will be 3.7w-2
