I think its the second one, the answer does not have a definite and, and cannot be put into a ratio.
Answer:
2.5
Step-by-step explanation:
per minute means to divide so 50/20 = 2.5
2x+6.
EG=EF+FG
EG=x+x+6
EG=2x+6
A neutral atom contains equal amount of proton and
electron.
A negative ion contains extra electrons hence there is
additional outer shell so it is expected that the radius is bigger than that of
a neutral atom.
While a positive ion contains less electron so there is
less outer shell so the radius is smaller than that of a neutral atom.
Arranging the radius in increasing order:
<span>positive ion, neutral atom, negative ion</span>
