Yes it is true because they act and behave the same way
Changing states of matter would be a physical change
The material on the right is a darker shade than the one on the left. Also the one on the right also is less of a block and a little more shagged
Answer:
Average atomic mass of potassium based on these relative abundances
Explanation:
The atomic mass of this element will be equal to the sum of product of its three isotopic masses and its fractional abundance
For isotope I -
Mass of Potassium-39 amu
Fractional abundance of Potassium-39 %
Mass of Potassium-40 amu
Fractional abundance of Potassium-40 %
Mass of Potassium-41 amu
Fractional abundance of Potassium-41 %
Average atomic mass of potassium based on these relative abundances
<span>subshells have two reasons of stability-
</span><span> 1) half filled and full filled subshells lead to symmetry as symmetry always increases stability in the nature.
</span>2)<span> in half filled and full filled subshells there are maximum no Of exchanges so exchanges releases energy so it increase stability.. Exchange of e-s also can b understood as delocalization of e-s which is similar like resonance and resonance always increases stability</span>
