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>
Answer:
a=2 and b=2...............
Bottom rectangle = 10*7 = 70
Top rectangle = 8*7 = 56
Side rectangle = 6*7 = 42
Side triangle = (1/2)*8*6 = 24
Side triangle = (1/2)*8*6 = 24
--------------------------------------------------
Total surface area = 70+56+42+24+24 = 216
Answer:
1. 16.62d + 26 = m 2. $152.34
Step-by-step explanation:
For the first part of the question you put the unknown variable multiplied by 16.62. Then add 26 which equals an unknown variable. For the second part, I multiplied 16.62 by 7 and added 26.
