Hint:We will get to know about the mass numbers, neutrons and electrons. We will write about the number of electrons that is present in the ion.
Complete step by step answer:The mass number (symbol A) also called mass number or nucleon number, is that the total number of protons and neutrons (together referred to as nucleons) in an atomic nucleus. It is approximately adequate to the atomic (also referred to as isotopic) mass of the atom expressed in mass units. The nucleon number is written either after the element name or as a superscript to the left of an element's symbol.
The neutron number, symbol N, is the number of neutrons during a nuclide. Atomic number (proton number) plus neutron number equals mass number: . Nuclides that have an equivalent neutron number but different proton numbers are called isotones. Nuclides that have an equivalent nucleon number are called isobars. From the nucleon number and number of neutrons, we will calculate the number of protons or electrons which is ).
Hence, the electronic configuration of this element would be 2, 8, 3. In order to become stable it would lose the last 3 electrons and gain 3 positive charges as given in the question. So, the resultant ion is left with 10 electrons.
Hence the correct answer is option B.
Additional information: Protons and neutrons constitute the nuclei of atoms. Since protons and neutrons behave similarly within the nucleus, and every feature a mass of roughly one mass unit, they're both mentioned as nucleons. The difference between the neutron number and therefore the number is understood because the neutron excess: D = N - Z = A - 2Z.
Note: In order to become a stable ion, the ion must lose the unpaired electrons which will result in the ion to get stabilised.Electrons are subatomic particles that hold an elementary charge of magnitude -1. The charge of an electron is equal in magnitude to the charge held by a proton (but has an opposite sign). Therefore, electrically neutral atoms/molecules must have an equal number of electrons and protons.
