Answer: The given Isotope is Xe which having symbol in terms of ΑΣΦ as ¹³²Xe₅₄.
Step-by-step explanation:
To find the isotope that is 11 times as heavy as 12C and has 18 times as many protons as Li, given as:
¹²C is the carbon with an atomic mass of 12.
Li is the lithium isotope with 3 protons.
Let's start by finding an isotope that is 11 times as heavy as 12C. The atomic mass of ¹²C is 12, so an isotope that is 11 times as heavy would have an atomic mass of 11 * 12 = 132.
Next, we need to find an isotope with 18 times as many protons as Li. Since Li has 3 protons, an isotope with 18 times as many protons would have 18 * 3 = 54 protons.
Hence, element with 54 protons and atomic mass 132 is Xe.
Therefore, Isotope is ¹³²Xe₅₄.
