Which of the following representations is correct for an atom X with 28 electrons and 30 neutrons?
\(^{30}_{28} X\)
\(^{28}_{30} X\)
\(^{58}_{30} X\)
\(^{58}_{28} X\)
Correct answer is D
\(X^{A = p + n = 28 + 30 = 58}_{Z = P = E = 28}\)
49.6g
37.2g
24.8g
12.4g
Correct answer is A
\(1 \to \frac{1}{2} \to \frac{1}{4} \to \frac{1}{8} \to \frac{1}{16} \to \frac{1}{32}\)
\(\frac{1}{32} = 1.55g\)
1 = 1.55 x \(\frac{32}{1} = 49.6g\)
