Answer: 3 neutrons are produced in the above nuclear reaction.

Explanation:

In a nuclear reaction, the total mass and total atomic number remains the same.

The nuclear reaction for the fission of Americium-244 isotope follows:

$^{244}_{95}\textrm{Am}\rightarrow ^{134}_{53}\textrm{I}+^{107}_{42}\textrm{Mo}+Y^1_0\textrm{n}$

To calculate Y:

Total mass on reactant side = total mass on product side

$\Rightarrow 244=134+107+(Y\times 1)\\\\\Rightarrow Y=244-241=3$

Hence, 3 neutrons are produced in the above nuclear reaction.

The number of protons and electrons in a neutral atom of the element are;

D. 29 protons and 29 electrons

The atomic number of an element is equal to the number of protons in the nucleus of each atom of that element.

Thus copper has an atomic number of 29, all atoms of copper will have 29 protons.
