What element is most reactive an en element with 7 valence electrons or an element with 8 valence electrons?
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.
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.
What determines the chemical reactivity or an element?
The higher the electronegativity of an element, the more reactive it is. Electronegativity is determined by the atomic number of an element, and the distance from the nucleus of the outer electron shell. The further from the nucleus an outer electron is, the easier it is to break its attraction to the atomic nucleus, and thus, the greater the element's propensity for forming molecular bonds. This answer is faulty since elements like Cesium are incredibly reactive, but have very low electronegativity and very low ionization energy, the energy to remove electrons. Because of that, elements at the top right and bottom left of the periodic table are both very reactive.
Which group of metals is charterised by a single valence electron and very active atoms?
Alkali metals, such as sodium and potassium, are characterized by having a single valence electron and very reactive atoms. They readily lose this outer electron to form +1 cations in chemical reactions.
Is chlorine reactive or not?
Chlorine is reactive and highly reactive because it has seven valence electrons, making it highly likely to gain one electron to achieve a stable electron configuration. It readily reacts with other elements to form compounds such as hydrochloric acid, sodium chloride, and many others.
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.
Is the element reactive or satble how do you know?
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.
What type of metals such as sodium have a single valence electron and very reactive?
Highly reactive metals with one valence electron are known as Alkali metals.
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.
What element is most reactive an en element with 7 valence electrons or an element with 8 valence electrons?
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.
Is one valence electron very reactive?
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
What type of metals such as sodium have a single valence electron and are very active?
The alkali metals (lithium, sodium, potassium, rubidium, caesium, and francium) all have a single valence electron and tend to be very reactive. Note that hydrogen also has a single valence electron and is very reactive but it does not become metallic except at very, very, very low temperatures.or very, very, very high pressures (at least theory predicts it would be).
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.
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.
How many electrons are in the outer energy level of group 7 a elements?
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.
What do all elements group 1 have in common in terms of electrons?
Group A1 of the Periodic Table (Hydrogen, Lithium, Sodium . . . ) is an Alkali Metal and only has one valance electron. If the element were to lose that electron, it forms an ion. Each element violently reacts when combined with water.
