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 is the atom of alkali metal?
The atom of an alkali metal, such as lithium, sodium, or potassium, typically contains one valence electron in its outermost shell. This makes alkali metals very reactive and eager to lose this electron to form a positive ion.
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.
What kind of atom tends to loose one electron?
The Alkali Metals loose one electron in order to achieve a nobel gas configuration.

Why is lithium more lighter than other alkali metals?
So it has the lowest atom number, the lowest mass as well

Of course, the electron structure of the atom of Francium "proposes" an alkali metal.
What type of ions do the alkali earth metals form?
Alkali metals, like all other metals, form positive ions. The atom, in order to achieve octet structure, loses the 1 valence electron to the environment. Thus, it will have 1 less electron than the element should, and as a result form a 1+ charged ion.
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. A link to our friends at Wikipedia is provided.
What do forces have to do with atomic radius of alkali metals?
Forces have an indirect impact on the atomic radius of alkali metals. As you move down a group of alkali metals in the periodic table, the atomic radius typically increases due to increased electron shells. The forces between the electrons and nucleus (electrostatic forces) contribute to the overall size of the atom in terms of atomic radius.
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.
Is a alkali a atom?
No. An alkali is a compound: the hydroxide of al alkali metal.
