What element is most likely to lose electrons to become a cation?
Ions formed due to gain or lose of electrons from an Atom. Ion is an atom which does not have a full valence band. The ions with least number of electrons on the outer most shell has a high risk of losing it's valence electron.
How many valance electrons does nitrogen?
5 valence electrons because it needs to gain 3 electrons in order to become stable
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 does a bromine anion contain?
A bromine anion has 8 valence electrons. This is because bromine, with 7 valence electrons, gains one extra electron when it forms an anion to achieve a full octet and become stable.
How many electrons to most elements need to become stable?
Most elements need 8 electrons in their valence shells.
How many valence electrons do most elements need to become stable?
8 valence electrons are needed for an element to become stable, which is why the noble gases do not interact with any other elements. They are already stable. However, the exception is Helium, the first noble gas, which only has two valence electrons. 8 valence electrons are needed on the 2nd and 3rd valence shells for any molecule to become stable.
What happens when it loses electrons?
all elements want to have a full valence shell and when an atom loses electrons it is said to become a cation.
The tendency of an element to react chemically is closely related to what?
its Atomic Mass.
How many valence electrons do the elements is group two have?
Group II elements (also called alkaline earth metals), have two valence electrons. To fill their outer shell, they therefore become ions with two positive charges, such as magnesium: Mg -> 2e- + Mg2+
What element is most likely to lose electrons to become a cation?
Ions formed due to gain or lose of electrons from an Atom. Ion is an atom which does not have a full valence band. The ions with least number of electrons on the outer most shell has a high risk of losing it's valence electron.
What shows the number of valence electrons in an atom pictorial fashion?
It's called the Periodic Table of the Elements, and it's very possibly the most useful thing in all of chemistry. The more you use it, the more comfortable you become with it, and the more it teaches you.
How many valence electrons are in aluminum?
Alkaline earth metals are group 2 elements and have 2 valence electrons.
How many valance electrons does nitrogen?
5 valence electrons because it needs to gain 3 electrons in order to become stable
What happens to the reactivity of metals from left to right across the perriodic table?
Elements become less reactive as you move from left to right across the periodic table. This is due to how many valence electrons (outer-most electrons) the element has; the less valence electrons, the more reactive the element.
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 does calcium lose?
Calcium loses 2 valence electron to become ionized.
How many valence electrons does a bromine anion contain?
A bromine anion has 8 valence electrons. This is because bromine, with 7 valence electrons, gains one extra electron when it forms an anion to achieve a full octet and become stable.
