how many neutrons are in the nucleus of an atom with an atomic mass of 80 amu and an atomic number of 35?\na 35\nb 45\nc 80\nd 115
Answer
Explanation:
Step1: Recall the formula
Atomic mass = Number of protons + Number of neutrons. Atomic number = Number of protons.
Step2: Calculate neutrons
Number of neutrons = Atomic mass - Atomic number. Given atomic mass = 80 and atomic number = 35. So, number of neutrons = 80 - 35 = 45.
Answer:
B. 45
