What is the element with a valence electron configuration of 2s2?
The element with a valence electron configuration of 2s2 is beryllium. Beryllium has 4 electrons, with 2 in the 2s subshell, which makes it have a valence electron configuration of 2s2.
Are having eight valence electrons makes atoms very reactive?
No, eight valence electrons completely fills the valence band and makes the atom inert. The most reactive atoms have either one valence electron or seven valence electrons.
Does Sodium have a full outer valence shell?
Sodium does not have a full outer valence shell. It has one electron in its outermost shell, which makes it very reactive and likely to lose that electron to achieve stability.
An electron in the outermost energy level of an atom is a?
The outermost electrons are called VALENCE electrons.
What is the number of valence electrons for Li and K?
Both lithium and potassium have one valence electron
How many balance electrons are in potassium?
Potassium has one valence electron. It is located in Group 1 of the periodic table, which contains the alkali metals. The presence of this single valence electron makes potassium highly reactive, as it readily loses this electron to achieve a stable electron configuration.
Is alkali metals highly reactive because of its one valence electrons?
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.
Hydrogen has how many valence electrons?
One. A hydrogen atom contains only one electron, and it is a valence electron.
How many valence electrons are in alkali metals?
one valence electrons
What is the number of valence electrons in Na?
Na has one valence electron i.e. 1 electron in valence(last) shell.
How many valence electrons does an atom of potassium have?
4
Have 1 valence electron?
Atoms with 1 valence electron are typically found in Group 1 of the periodic table, known as the alkali metals. Examples include lithium, sodium, and potassium, all of which have one valence electron in their outermost energy level. This lone valence electron makes these elements highly reactive.
