Rubidium has one electron in its outer level What will it most likely do in a reaction?
MissC313
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.

Which electron on an atom is the most likely one to be removed during a chemical reaction?
Electrons called valence electrons are most likely removed. These are the outermost energy level electrons.
Why does the luminol light reaction stop after a period of time?
The luminol reaction is an example of "chemiluminescence". This is when a chemical reaction yields a product in an electronically excited state (at least one electron in the product is at a level above the ground state). The excited product loses energy in the form of a photon of light when the electron drops to the ground state level. In the case of luminol the reaction is an oxidation under alkaline conditions and the reaction stops when either all the luminol, all the oxidising agent or all the alkali has been converted
In a protein complex for the light reaction why is energy transferred from pigment molecule to pigment molecule to a special chlorophyll a molecule and eventually to the primary electron acceptor?
The molecular environment lets it boost an electron to a higher energy level and also to transfer the electron to another molecule
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.

What element contains 1 electron in its fifth energy level?
Rubidium
How many valence electrons are in rubidium?
In common with all the other Alkali Metals, Rubidium has one valence electron.

Electrons called valence electrons are most likely removed. These are the outermost energy level electrons.
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?
in the same way as sodium/potassium forms an ion. Lithium has an electron configuration of 2,1 Sodium has an electron configuration of 2,8,1, Potassium has an electron configuration of 2,8,8,1 Rubidium has an electron configuration of 2,8,8,18,1 Caesium has the electron configuration of 2,8,8,18,18,1 Notice in all cases the last number is '1'. This represents the outer most electron, shell with one electron. Since it is the outer most electron and is shielded by energy shells of electrons from the nucleus, this outer most electron is not strongly held to the atom. The atom readily releases this outermost electron , and the process is called ionisation. Chemically it is represented by the formula M(g) = M^+(g) + e^- NB 'M' is an ATOM 'M^+' is an ION (Not an atom).
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.
What information does the first quantum number of an electron give?
The energy level the electron is in
What property indicates that alkali metals are highly reactive?
the fact that the atoms have only 1 electron orbitting the outer level. it is very easy for them to lose this one electron, hence, a quick, easy reaction.

Electron configurations is most likely to result in an element that is relatively inactive?
A filled highest occupied principal energy level
