Aneutral isotope has a mass number of 65 and 36 neutrons. identify the element symbol of this isotope and determine the number of protons and electrons.

element symbol : Cu.

Number of protons= 29

Number of electrons = 29

Explanation:

Mass number is defined as the sum of number of protons and neutrons that are present in an atom.

Mass number = Number of protons + Number of neutrons   (i)

Atomic number is defined as the number of protons or number of electrons that are present in an atom in a neutral element.

Atomic number = Number of electrons = Number of protons   (ii)

Given mass number = 65

Number of neutrons  = 36

using (i) , Mass number = Number of protons + Number of neutrons

65=  Number of protons + 36

Number of protons = 29

Using (ii) ,  Atomic number  = Number of protons = Number of electrons  = 29

Thus the element is copper with atomic number of 29 and element symbol is Cu.

1. The element has 29 Protons.

2. The symbol of the element is Cu

3. The element has 29 electrons.

From the question given above, the following data were obtained:

Mass number = 65

Neutron = 36

We'll begin by calculating the number of protons.

Mass number = 65

Neutron = 36

Mass number = Proton + Neutron

65 = Proton + 36

Collect like terms

65 – 36 = Proton

Therefore, the element has 29 protons.

Next, we shall determine the symbol of the element.

The proton number is simply the atomic number of an element.

Thus, the element has atomic number of 29 since it's proton number is 29.

From the period table, element with atomic number of 29 is copper and the symbol of copper is Cu.

Finally, we shall determine the number of electrons in the element.

Proton = 29

Since the isotope of the element is neutral, it means the element has equal number of protons and electrons.

Thus,

1. The element has 29 Protons.

2. The symbol of the element is Cu

3. The element has 29 electrons.
