Rubidium has one electron in its outer level What will it most likely do in a reaction?
It will lose its outermost electron to a nonmetal. The Rb atom will become a positively charged ion with a charge of 1+ , and the nonmetal will gain the electron and become a negatively charged ion. The electrostatic attraction between the oppositely charged ions forms an ionic bond.
What else can I help you with?
Which valence electron if further from the nucleus rubidium or strontium?
Rubidium has one valence electron in the 5th energy level, while strontium has two valence electrons in the 5th energy level. Since rubidium has only one valence electron compared to strontium's two, the valence electron in rubidium is further from the nucleus. This is due to the increasing number of electron shells as you move down a group in the periodic table.
Which electron on an atom is the most likely one to be removed during a chemical reaction?
The valence electron, which is the electron located in the outermost energy level of an atom, is the most likely to be removed during a chemical reaction. This is because valence electrons are involved in the formation of chemical bonds and determining an atom's reactivity.
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.
When is an electron in an atom likely to move from energy level to another?
First, in order for an electron in an atom to change energy levels, there must be a place for it in the new energy levels. Quantum Mechanics puts very strict rules on how many electrons can be in the same energy level. Assuming there is a place for it, then it is very likely to move into a lower energy level. It is not possible for it to move into a higher energy level unless something from the outside comes in and knocks it up. There is no way to predict when an electron will drop down into a lower energy level. When something like a photon comes in from the outside and knocks the electron into a higher level, it usually drops back down pretty quickly, but not necessarily.
When is electron in an atom likely to move from one energy level to another?

What element contains 1 electron in its fifth energy level?
Rubidium
Which valence electron if further from the nucleus rubidium or strontium?
Rubidium has one valence electron in the 5th energy level, while strontium has two valence electrons in the 5th energy level. Since rubidium has only one valence electron compared to strontium's two, the valence electron in rubidium is further from the nucleus. This is due to the increasing number of electron shells as you move down a group in the periodic table.
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.
Which electron on an atom is the most likely one to be removed during a chemical reaction?
The valence electron, which is the electron located in the outermost energy level of an atom, is the most likely to be removed during a chemical reaction. This is because valence electrons are involved in the formation of chemical bonds and determining an atom's reactivity.
How many valence electrons are in rubidium?
1 valence electron. It is an alkali metal and all alkali metals have one atom on their last energy level.
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.
What would happen if a piece of rubidium were dropped in water?
As rubidium is a group one element, it has only the 5s1 electron in its outer energy level which makes it very reactive. So, if we were to drop some rubidium in water it would react rapidly to produce smoke and small sparks. There are lots of YouTube videos of this reaction so take a look.
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.
Which term refers to the region of an atom where an electron is most likely to be found?
That would be the electron cloud. This is like the orbital model where there are electrons in each orbit level but the electron's location can not be predicted so it is said to be most likely at a point in the electron cloud.
How do you write the shorthand electron configuration for rubidium?
[Kr] 5s(1)or, in the longer version1s(2) 2s(2) 2p(6) 3s(2) 3p(6) 4s(2) 3d(10) 4p(6) 5s(1)Note: All the numbers in the parentheses are supposed to be in superscript (not sure how to do it) and they represent the number of electrons in the sublevel. The first configuration uses the noble gas Krypton (basically an abbreviated form of electron configuration). Both configurations are according to the Aufbau principle (lower energy levels are filled in first). So, if you're confused when you see, for example, 4s before 3d, this is just according to the principle.
Which element is most likely to donate one electron Be Cs Rn or He?
Cs (cesium) is most likely to donate one electron as it is classified as an alkali metal with a single valence electron in its outermost energy level.
What characteristic electron configuration are shared by Lithum sodium Potassium and Rb?
Lithium, sodium, potassium, and rubidium all belong to Group 1 of the periodic table, known as the alkali metals. They all have one valence electron in their outer energy level, giving them similar electron configurations where the outer electron is in the s orbital. Specifically, their electron configurations end in s¹.
