2 answers:
Explanation:
Z = atomic mass of the element and , A = atomic mass of the element .
a) Z = 11, A = 23
Element = Sodium
symbol: ²³₁₁Na .
b) Z = 28, A = 64
Element = Nickel
symbol: ⁶⁴₂₈Ni .
c) Z = 50, A = 115
Element = tin
symbol: ¹¹⁵₅₀Sn .
d) Z = 20, A = 42
Element = Calcium
symbol: ⁴²₂₀Ca .
Answer:
(a)
(b)
(c)
(d)
Explanation:
Hello,
In this case, Z stands for the isotope's atomic number and A for the isotope's atomic mass, in such a way, looking for each isotope one concludes that the proper symbol, in the form of turn out being:
(a)
(b)
(c)
(d)
