What atom has one valence electron?
hydrogen and the alkali metals lithium, sodium, potassium, rubidium, cesium, and francium all have one valence electron.
Is Niobium an alkali metal?
No, Nb, atom no. 41, is in group 5 (period 5) of the transition metals (4d-trans.).Alkali metals are in group 1, like Na and K.
What happens to the melting point of the alkali metals as the atom increase in size?
As we move down the group, the melting point decreases.
How many alkali metals are on the periodic table?
6: lithium(Li) ,sodium(Na) , potassium(K) , rubidium (Rb) , cesium (Cs) and Francium(Fr). Practically,only the first five can be termed alkali metals,because there is not enough Francium in the planet to examine its characteristics. Of course, the electron structure of the atom of Francium "proposes" an alkali metal.
Is hydrogen a alkali metal or alkaline metal?
Alkali metals can be substituted for hydrogen. Any of them. They include lithim (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs) and francium (Fr). The alkali metals are in group one of the periodic table of the elements, and are all stacked up in the column below hydrogen. All the alkali metals are all organized with a lone electron in their outer most shell, or valence shell (in the neutral atom) and all of the alkali metals would like to loan out that electron to anything that would like to borrow it. It turns out that the reactivity of alkali metals are least to greatest from the top of the column to the bottom. This is because of electron screening.

What kind of atom tends to loose one electron?
The Alkali Metals loose one electron in order to achieve a nobel gas configuration.
What atom has one valence electron?
hydrogen and the alkali metals lithium, sodium, potassium, rubidium, cesium, and francium all have one valence electron.
Is Niobium an alkali metal?
No, Nb, atom no. 41, is in group 5 (period 5) of the transition metals (4d-trans.).Alkali metals are in group 1, like Na and K.
How many valence electrons are in rubidium?
In common with all the other Alkali Metals, Rubidium has one valence electron.
What happens to the melting point of the alkali metals as the atom increase in size?
As we move down the group, the melting point decreases.
Why is lithium more lighter than other alkali metals?
So it has the lowest atom number, the lowest mass as well

Which alkali metals possesses highest reducing power?
The tendency of alkali metals to act as strong reducing agents is evident from the fact that these metals can liberate H2 from H2 O and acids. 2M+2H2O-----------------2MOH+H2 2M+2HCl------------------2MCl+H2We have already seen that Li atom loses its ns1 electron with great difficulty while Cs atom should have maximum reducing power among the alkali metals . In other words ,we can also say Li -atom ,because of its maximum ionisation energy, should have minimum reducing power and Cs atom ,because of its minimum ionisation energy ,should have maximum reducing power .The high valves of oxidation potential show that alkali metals can lose their ns1 electron quite readily and hence have a strong tendency to act as reducing agents.
A Sodium atom has 1 electron in its outer shell which can hold 8 electrons. To achieve stability the sodium atom does what?

Why are transition metals not as reactive as alkali metals and akaline earth metals?
They are less reactive because they have 2 electrons in the outer shell of the atoms and they like to be full and the alkali metals only have 1 electron in the outer shell of the atom, and it is easyer to give away 1 electron than 2 so they are more reactive than other elements. The electronegativity (Pauling values) is lower for the alkali metals.
