Answer:
Mean: 14.8888888889
Median: 16
Mode: 7,16
Range: 18
Explanation:
7,7,11,12,16,16,18,22,25
Mean: (7+7+11+12+16+16+18+22+25)/9
Mode is Bimodal since there are two of them
Answer: See below
Explanation:
For this question, we are given the volume, and we want to find the diameter. We have to work backwards to get our radius, then to find the diameter.
(Volume of cylinder)
(The π cancel out)
(Plug in h=8)
(Divide 8)
(Square root of 9 is 3)
Now that we have our radius, we can find our diameter.
(Equation for diameter)
(Plug in r=3)
(Multiply)
Ionic charge increases from left to right in periodic table which results in a decrease in ionic radius.
Ionic charge is the electrical charge of an ion formed when when an atom gains or losses electron.
Metals form ionic charge (cation) by the loss of electron while non-metal form ionic charge (anion) by the gain of electron.
- This ionic charge increases across the group and consequently, results in a decrease of ionic radius.
- When a positive ion (cation) transfers electron to the negative ion (anion) an Ionic bond will be formed.
<u>For example</u>;
- ionic charge of group 1 elements = +1
- ionic charge of group 2 elements = + 2
- ionic charge of group 3 elements = + 3
- ionic charge of group 4 elements (carbon group) = -4 or +4, (<em>they don't usually form ions</em>)
- ionic charge of group 5 elements = -5
- ionic charge of group 6 elements = -6
- ionic charge of group 7 elements = -7
Thus, we can conclude that ionic charge increases from left to right in periodic table which results in a decrease in ionic radius.
