To calculate the energy it takes to remove a single electron from an atom on the surface of solid rubidium (Rb), you need to divide the given energy by Avogadro's number since 1 mole contains Avogadro's number of particles (6.022 x 10^23). Therefore, the energy to remove a single electron from an atom on the surface of solid rubidium would be 208.4 kJ divided by Avogadro's number.

What is rubidium ionization energy?
Rubidium has a first ionization energy of about 403 kJ/mol. This is the energy required to remove one electron from a neutral rubidium atom to form a rubidium ion. Subsequent ionization energies increase as more electrons are removed.
Why does one electron in a rubidium atom occupy a 5s orbital rather than a 4d or 4f orbital?
The 5s orbital has a lower energy level than the 4d or 4f orbitals in a rubidium atom, according to the aufbau principle. Electrons fill orbitals starting from the lowest energy level to the highest energy level. This is why the electron fills the 5s orbital before the 4d or 4f orbitals in a rubidium atom.
Are electrons located in energy levels or electron cloud?
Electrons are located in energy levels within the electron cloud.
How is rubidium used in photo cells?
Rubidium can be used in photoelectric cells due to its high sensitivity to light. When light strikes the rubidium surface, it can cause electrons to be released, generating an electric current. This property makes rubidium a suitable material for converting light energy into electrical signals in devices such as photomultiplier tubes.
What describes the energy possessed by electrons?
The energy of electrons is expressed in eV (electron volts).
Why does rubidium have a larger atomic radius than sodium?
Rubidium has a larger atomic radius than sodium because rubidium has more electrons and energy levels, leading to increased electron-electron repulsion and a larger atomic size. Additionally, the outermost electron in rubidium is in a higher energy level compared to sodium, contributing to a larger atomic radius.
What is rubidium ionization energy?
Rubidium has a first ionization energy of about 403 kJ/mol. This is the energy required to remove one electron from a neutral rubidium atom to form a rubidium ion. Subsequent ionization energies increase as more electrons are removed.
Why cesium has a lower first ionization energy then rubidium?
Cesium has a lower first ionization energy than rubidium because cesium has a larger atomic size and weaker effective nuclear charge. This means that the outermost electron in cesium is further away from the nucleus and experiences less attraction, making it easier to remove, resulting in a lower first ionization energy.
How many valence electrons are in rubidium?
Rubidium has 1 valence electron. It is found in Group 1 of the periodic table, also known as the alkali metals, and elements in this group typically have 1 valence electron.
What element contains 1 electron in its fifth energy level?
Rubidium
How many occupied energy levels does a rubidium atom have?
Rubidium has 5 shells because the first shells has 1 electron, the next 2 shells have 8 electrons, the fourth shells has 18 electrons and the last shells has 2 electrons. the atomic number is 37, 1+8+8+18+2=37. Therefore Rb has 5 shells. :D

The 5s orbital has a lower energy level than the 4d or 4f orbitals in a rubidium atom, according to the aufbau principle. Electrons fill orbitals starting from the lowest energy level to the highest energy level. This is why the electron fills the 5s orbital before the 4d or 4f orbitals in a rubidium atom.
If electrons have the most energy in an atom electrons in an electron cloud electrons in the outermost electron shell electrons in the innermost electron shell electrons in the nucleus?
Electrons in the outermost electron shell have the most energy in an atom. The energy of an electron increases as it moves further away from the nucleus. Electrons in the innermost shell have the least energy, while electrons in the nucleus have the highest energy due to their proximity to the protons.
How does rubidium form an ion?
Rubidium forms a +1 cation (Rb+) by losing one electron to achieve a stable electron configuration. Rubidium has one valence electron in its outermost shell, so by losing this electron, it becomes a cation.
What is the electron configuration of rubidium?
The condensed electron configuration of rubidium is [Kr] 5s1 in the 1st group of period V
Are electrons located in energy levels or electron cloud?
Electrons are located in energy levels within the electron cloud.
