If an element has one valence electron it IS very reactive. ex. Fr and Cs are extermely reactive elements.
This is because the one valence electron is so far from the nucleus there is not a strong force making it stay with the element.
Alkali metals
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.
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.
Alkali metals are more reactive as they are in group 1 and therefore has only one valence electron. With only one valence electron, its easy for them to achieve inert configuration/ noble gas configuration, which makes them so reactive.
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.
To start off, the electrons on the outermost energy level of an atom are called valence electrons. You can tell how many valence electrons an energy level has by finding out its group number. If an element is in group one, than it has one valence electron.
Highly reactive metals with one valence electron are known as Alkali metals.
Highly reactive metals with one valence electron are known as Alkali metals.
Highly reactive metals with one valence electron are known as Alkali metals.
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.
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.
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.
HYDROGEN
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.
The most reactive elements have either 1 valence electron or 7 valence electrons
Alkali metals are more reactive as they are in group 1 and therefore has only one valence electron. With only one valence electron, its easy for them to achieve inert configuration/ noble gas configuration, which makes them so reactive.
no it does not. NaCl is a neutral compound.
because of having only one electron in valence shell
