The element with one valence electron and is very reactive is sodium. Sodium is a member of the alkali metal group and readily gives up its outer electron to form positive ions in chemical reactions.
When we say valence electron we mean the number of electron left it the outermost shell of element, valence electron can be positive of negetive. If an element need much electrons to be octet, that means that the element is not reactive than the one who will give out electrons, the the one who can give electrons much are less reactive than the one who can give a litle and the reaction will be normal as it is soppused to be, Eg lithium and berylium. Lithium is more reactive than berylium because lithuin has 1valence electron while berylium has 2....reactivity goes with the action of valence electron in an element
Yes, alkali metals are highly reactive because they have one valence electron that they readily donate to achieve a stable electron configuration. This makes them extremely reactive with water and air, which results in explosive reactions.
An element with a complete valence electron shell is a noble gas. Noble gases have a full outer electron shell, making them stable and non-reactive. Examples include helium, neon, and argon.
the element with seven valence electrons will be more reactive. The reason for this is that elements want to always want to have a full valence shell (they always want 8, like a noble gas). The element with eight valence electron is happy with its full shell and will not want to get rid of any electrons.
because they have one valence electron that is easily removed to form a positive ion.

reactive parts of an electron?
Highly reactive metals with one valence electron are known as Alkali metals.
If the element has a full valence shell, such as the noble gases, then it is unreactive. It the element is missing few valence electrons of has few valence electrons, then the element is very reactive, such as the sodium.
The farther the valence electron are from the nucleus, the more easily they can be lost therefore the more reactive the element is. i.e potassium would be more reactive than sodium (check their valence electrons)
