Neutrons = 118
<h3>Further explanation </h3>
The elements in nature have several types of isotopes
Isotopes are elements that have the same Atomic Number (Proton)
Atomic mass is <em>the average atomic mass of all its isotopes </em>
The most abundant isotope of gold (Au) is isotope Au-197
So the atomic mass of Au = 197
and the atomic number of Au = 79
Atomic mass is the sum of protons and neutrons
Atomic Number (Z) = Atomic mass (A) - Neutrons
Neutrons = A - Z
So neutrons for Au-197 :
The distance between a carbon atom and an oxygen atom in the co molecule is 0.63
<h3>What is the distance?</h3>
Distance is the measurement of the farness of two objects from each other.
The distance between the molecules can be calculated by the given formula
Putting the values in the equation
Thus, the distance between a carbon atom and an oxygen atom in the co molecule is 0.63
