The First Law of Thermodynamics helps to determine the mass of the silver block:
The mass of the silver block is:
Electrons located in the outermost shell of an atom are called valence electrons. The outermost electrons are involved in chemical reactions. The electrons in the outer shell determine the reactivity of the element. For example, potassium (2,8,8,1) has one valence electron.
Answer:
The answer to your question is letter A
Explanation:
Abundance Atomic mass
V-50 0.25% 49.947
V-51 99.750% 50.944
Formula
Average atomic mass = [V-50-Abundance x V-50-Atomic mass] +
[ V-51-Abundance x V-51-Atomic mass]
Substitution
Average atomic mass = [ 0.0025 x 49.947] + [0.9975 x 50.944]
= 0.125 + 50.817
Result
= 50.942 amu
