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.
1. Which one of the following statements concerning elements in the Periodic Table is correct a) Elements of the same group all have the same number of electrons in the outermost occupied electron she?
The correct statement is that elements of the same group in the Periodic Table all have the same number of electrons in their outermost occupied electron shell, also known as valence electrons. This similarity in valence electron configuration leads to comparable chemical properties among the elements within that group. For example, all alkali metals (Group 1) have one valence electron, making them highly reactive.
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 the correct number of valence electrons for the element rubidium Rb atomic 37.?
Rubidium (Rb), with an atomic number of 37, has one valence electron. It is located in Group 1 of the periodic table, which consists of alkali metals. These elements typically have a single electron in their outermost shell, making them highly reactive. Thus, rubidium has a valence electron configuration of (5s^1).
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.

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 the correct number of valence electrons for the element rubidium Rb atomic 37.?
Rubidium (Rb), with an atomic number of 37, has one valence electron. It is located in Group 1 of the periodic table, which consists of alkali metals. These elements typically have a single electron in their outermost shell, making them highly reactive. Thus, rubidium has a valence electron configuration of (5s^1).
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.
