Answer:
Fe
Explanation:
<em>Ferrum</em><em> </em>[Iron] has the most stable nucleus because of <em>binding</em><em> </em><em>energy</em><em> </em><em>per</em><em> </em><em>nucleon</em><em>.</em><em> </em>Although Uranium<em> </em>is<em> </em>another possibility, in this case, it is more radioactive than Iron. It disintegrates very swiftly that all is done so, just to achieve stability.

Answer:
0.675 atm
513 Torr
Explanation:
Given is that, the atmospheric pressure on the surface of Venus is
6.84 X 10⁴ Pa.
1 atm (atmospheric pressure) is equal to 101325 pascal (Pa).
To convert divide the pressure value by 101325.
Pressure in atm = 
= 0.675055 atm
Rounding it off to 3 significant digits: 0.675 atm
Now, one Torr is 133.322 Pa. For conversion, divide the pressure value by 133.322.
Pressure in Torr = 
=513.04219 Torr
Rounding it off to 3 significant digits: 513 Torr
