What is the number of valence electrons in group one?
Valence electrons are the electrons in the furthest electron shell from the nucleus.For the first three rows, essentially, the number of valence electrons is the number of squares the element is away from the beginning of the row at the left.For example. Sodium is the first (group 1) it has 1 valence electron. Magnesium is the second, it has 2 valence electrons.
What is the number of valance electrons in atoms from alkali metals?
they have one valence electron. this is why they are so highly reactive and cannot be found pure in nature.
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.
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.
How many valence electrons do the elements of alkali metals have?
Valence electrons are the electrons present in the outermost shell of an atom.You can easily determine the number of valence electrons an atom can have by looking at its Group in the periodic table.For example, atoms in Groups 1 and 2 have 1 and 2 valence electrons, respectively.Atoms in Groups 13 and 18 have 3 and 8 valence electrons, respectively.
What is the number of valence electrons in group one?
Valence electrons are the electrons in the furthest electron shell from the nucleus.For the first three rows, essentially, the number of valence electrons is the number of squares the element is away from the beginning of the row at the left.For example. Sodium is the first (group 1) it has 1 valence electron. Magnesium is the second, it has 2 valence electrons.
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.
The most reactive elements have how many valence electrons?
The most reactive elements require to lose or gain the least number electron(s) to attain a noble gas structure. These are elements in group one as they need to lose one electron, and elements in group seven as they need to gain one electron.
What is the number of valance electrons in atoms from alkali metals?
they have one valence electron. this is why they are so highly reactive and cannot be found pure in nature.
What makes the elements in the halogen group reactive?
The halogen group elements are reactive because they have seven valence electrons, making them one electron short of a full outer shell. They are highly reactive and tend to gain an electron through reactions with other elements to achieve a stable electron configuration.
Elements that have one valence electron tend to?
Elements that have one valence electron tend to be highly reactive and readily form positive ions by losing that electron to achieve a stable electron configuration. These elements include alkali metals like lithium, sodium, and potassium.
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 type of metals such as sodium have a single valence electron are very reactive?
Highly reactive metals with one valence electron are known as Alkali metals.
Why are the alkali metals and halogen among the most reactive elements on the periodic table?
because to be stable they need 8 atoms in outer energy level halogens need one so are highly reactive. alkali need 7 so are highly reactive( not as highly as halogens)
What type of metal such as sodium have a single valence electrons and are very reactive?
Highly reactive metals with one valence electron are known as Alkali metals.
Why do all elements in group 1 react in similar way?
All elements in the same group (or column) in the periodic table have the same number of valence electrons and it is the number of valence electrons that determine the reactivity of most elements.See the Related Questions to the left for more information.
Why are group one elements largely ionic?
Group 1 elements have one electron in their outermost electron shell, making it easier for them to lose this electron to achieve a full outer shell. This electron loss results in the formation of positively charged ions, which readily form ionic bonds with other elements to achieve a stable electron configuration.
