In 52.6 mins the 10 mg of iodine will be divided by its half-life which is 2 it will become 5 mg (in 52.6 minutes ) and same procedure will be followed until it reach 99% out of the patient's system.
The answer is 368 minutes will it takes the iodine to be absorbed in one's system.
The sun is a star.
If you were talking about that
The electron distribution in the Si atom : D. 2,8,4
<h3>Further explanation</h3>
The maximum number of electrons that can be filled in the nth electron shell is 2n²(n=shell)
- K shell (n = 1) maximum 2 x 1² = 2 electrons
- L shell (n = 2) maximum 2 x 2² = 8 electrons
- M shell (n = 3) maximum 2 x 3² = 18 electrons
- N shell (n = 4) maximum 2 x 4² = 32 electrons
Electron configuration of Si : 1s² 2s2²2p6⁶3s²3p² = 14 electron
The electron distribution :
K shell = 2
L shell = 8
M shell = 4
This has only only three sig figs because it is 546.000 the zeros are just place holders so thus meaning they are not significant. It is just another way to write 546 because in that number there is also 3 sig figs. They are just trying to throw you off. Just watch out because if the example is 540 then it is just two significant digits, and it were to be 540. then it be three cause that "." makes the zero significant. <span />
Answer:
Mass is the amount of matter in an object.
Weight is how much an object weighs.
Hope this helps!
