Question

an element with an atomic number of 37 and an atomic mass of 85 has how many neutrons in each atom?

Explanation:

Step1: Recall neutron calculation formula

The number of neutrons in an atom is calculated by the formula: $ \text{Number of neutrons} = \text{Atomic mass} - \text{Atomic number} $

Step2: Substitute given values

Given atomic number = 37 and atomic mass = 85. Substitute into the formula: $ 85 - 37 = 48 $

Answer:

48 (corresponding to the orange option with value 48)
