The Bohr Model of Europium – An Overview

Europium is a rare earth element that has an atomic number of 63 and is found in the Earth’s crust. It is essential for the production of fluorescent lamps and computer monitors, and its unique magnetic properties make it extremely valuable in electronic devices.

The structure of Europium nucleus

The nucleus of Europium comprises a specific number of protons and neutrons. In Europium, the nucleus is composed of 63 protons and between 89 and 153 neutrons, depending on the isotope.

The isotope with the highest abundance in naturally occurring Europium is Europium-151, which has 88 neutrons. The number of protons identifies the element, whereas the number of neutrons determines the isotope of the element.

The electron shells of Europium

Electrons are the negatively charged particles that orbit the nucleus of an atom. The electrons of Europium occupy different electron shells.

The first shell can hold up to two electrons, while the second and third shells can hold up to eight electrons each. The shells closer to the nucleus have lower energy levels than those further away.

Distribution of electrons in Europium

Europium has a total of 63 electrons distributed among the different shells. The electron configuration of Europium is [Xe] 4f7 6s2.

This implies that Europium has four f-orbital electrons (in the 4f subshell), two s-orbital electrons (in the 6s subshell), and no electrons in the d-orbital or p-orbital subshells.

Number of electrons in each shell

The number of electrons per shell tells us how many electrons are in each shell. In Europium, the first shell has two electrons, the second shell has eight electrons, and the third shell has 18 electrons.

The fourth shell of Europium has 25 electrons.
