Every alkali metal has only one electron in the outermost energy level. They give it away to form monopositive ions which have stable electron configurations ending with ns2 np6 (where n is a counting number between 2 and 7 inclusive).

How can you use the word stable to explain why the alkali metals tend to lose valence electrons?
Alkali metals, have only one valence electron so they will "want" to lose it to achieve a stable electron arrangement.
How many valence electrons do alkali metals lose to obtain an octet?
they lose one electron
Explain why alkali metals are extremely reactive?
This is because they only have on valance electron. This makes it easier to react with other elements and more often also.
What are the similarities between the noble gases and alkali metals?
There are no similarities. Noble gases (group 18 elements) have completely filled orbitals with stable electron configuration and are generally unreactive. Alkali metals (group 1 elements) have one valence electron. They are reactive. When these lose one electron, they form ions which has the electronic configuration of the nearest noble gas.
Which elements are likely to lose electron?
Group I elements (that is alkali metals)

What will the alkali metals family do with its valence electrons during a compound formation?
Alkali metals lose one electron in chemical reactions.
Which element is most likely to lose an electron?
Lithium would be most likely to lose electrons in a chemical bond.
How does sodium reach its desired state?
Sodium is an alkali metal. All alkali metals have 1 electron in the valence shell. This means that the "desired state" is to have a full valence shell configuration. So, in order for sodium and other alkali metals to reach this state, it has to LOSE one electron, making it a positive ion (cation).

What metals that lose one electron when they react with water to form alkaline solutions?
Alkali metals
Why are alkali metals more reactive than transition metals?
Groups 3-12 do not have individual names. Instead, all of these groups are called transition metals. The atoms of transition metals do not give away their electrons as easily as atoms of the Group 1 and Group 2 metals do. So, transition metals are less reactive than alkali metals and alkaline-earth metals are.
How many valence electrons do alkali metal family members have?
The key to this answer is the phrase "valence electrons". Alkali metals are in the first column of the periodic table and include elements such as Lithium, Sodium and Potassium. These elements typically lose ONE electron when they participate in a chemical reaction, therefore they have ONE valence electron.
What metals react with other metals what happens to the valence electrons of the metal atoms?
== == When metals react with other elements, the atoms of the metals give up their valence electrons.
