Answer:
an Additional shell
Explanation:
Potassium has an additional energy level when compared to sodium. This is due to an extra shell added. In the periodic table when you go down the group, the atomic radius increases due to increasing energy levels.
The atomic radius mean the distance from the center of the nucleus to the valance shell. it actually describes the size of the atom
That's kind of a ponderous way to describe it, but your 'X' represents
the absolute temperature of the ideal gas.
Using the specific heat capacity formula:
q = mc ∆ t
60.0 J = (6g)(x)(11*C)
x = 0.9 J/g*C
Aluminum
False
explanation
All of the elements with atomic numbers 1 to 92 can be found in nature, have stable or very long half-life isotopes, and are created as common products of the decay of uranium and thorium.
