Answer: A

Explanation:

A Gold (Au) atom has 79 protons and 79 electrons. A typical gold atom has 118 neutrons, though there are 18 other radioisotopes discovered so far. 79 is its charge (atomic number), which is both its proton number and electron number

D. Protons, if you change the number of protons you change the element. You cannot change nuclei. You can have the same element with different numbers of neutrons (isotopes) and different numbers of electrons (ions). So protons will allow you to identify the element.

Yuri [45]

For a cell  operated to produce a constant voltage of 1.50 V, the electrical work done  is mathematically given as

W=2.077*10^{-7}

<h3>What is the electrical work done?</h3>

Generally, the volume of Br2  is mathematically given as

Vb=\frac{0.38*3.12}{159.809}

Vb=7.18*10^-3ml

Therefore, the quantity of charge

q=(1.436*10^-2)*9.644*10^4

q=1.385^{-4}c

In conclusion, work done

W=Eq

W=1.50*1.385^{-4}

W=2.077*10^{-7}
