Question

6.

Answer 1

Answer:

Ni^2+

Explanation:

The following data were obtained from the question:

Proton = 28

Electron = 26

Neutron = 34

Next, we shall determine the atomic number of the element.

Atomic number of an element is simply defined as the number of protons in the atom of an element.

Thus,

Atomic number = proton number

Proton = 28

Atomic number = proton number = 28

Atomic number = 28

Therefore, the element is Nickel since no two elements have the same atomic number.

Finally, we shall determine the charge on the Nickel atom as follow:

Proton = 28

Electron = 26

Charge on atom =

Charge on atom = Proton – Electron

Charge on atom = 28 – 26

Charge on atom = +2

Therefore, we can represent the Particle as Ni^2+
