Answer:
5.65mg of the isotope remains
Explanation:
The radioactive decay follows the equation:
Ln[A] = -kt + ln[A]₀
<em>Where [A] is amount of the isotope after time t, k is decay constant, and [A]₀ is initial amount of the isotope.</em>
k = ln 2 / Half-life
k = ln 2 / 3.82 days
k = 0.18145days⁻¹
Replacing:
Ln[A] = -0.18145days⁻¹*10.1days + ln[35.3mg]
ln[A] = 1.7312
[A] = 5.65mg of the isotope remains

Answer:
If a compound is made from a metal and a non-metal, its bonding will be ionic.
If a compound is made from two non-metals, its bonding will be covalent.
hope that helps : )
You have not mention here about those elements but the general concept for this is the:
uneven distribution ------> polar
even distribution -------> non-polar
