What causes an element to be reactive?
In the short form: elements are striving to completely fill valence shells of electrons to reach a quantumly stable energy state. They react to take electrons away from elements willing to give up electrons or share outer shell electrons with elements they aren't strong enough to steal from.
Why are the valence electrons of an atom the only electrons likely to be involved in bonding to other atoms?
It is because only certain (the outer) electrons are available for chemical bonding that they are called valence electrons. By definition, the electrons available for bonding are called valence electrons. The others are more tightly bound to the nucleus.
Elements that have one valence electron tend to?
An element that has one valence electron tends to be more reactive, is able to form ions, and can become charged When an element has all eight valence electrons, they are more stable.
How do you calculate valency of silver nitrate?
Silver Nitrate is a compound. A compound is formed in such a way that its constituent elements share or transfer electrons in order to become stable. So, the valencies are complete. A compound is stable. Only elements have valence electrons.
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 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.
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 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.
What causes an element to be reactive?
In the short form: elements are striving to completely fill valence shells of electrons to reach a quantumly stable energy state. They react to take electrons away from elements willing to give up electrons or share outer shell electrons with elements they aren't strong enough to steal from.
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.
What do bromine and chlorine have in common?
The atoms of both elements have seven valence electrons and a strong tendency to abstract, from a less electronegative atom, an electron to complete their valence shells and thereby become an anion.
Elements that have one valence electron tend to?
An element that has one valence electron tends to be more reactive, is able to form ions, and can become charged When an element has all eight valence electrons, they are more 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.
How do you calculate valency of silver nitrate?
Silver Nitrate is a compound. A compound is formed in such a way that its constituent elements share or transfer electrons in order to become stable. So, the valencies are complete. A compound is stable. Only elements have valence electrons.
Which elements are most likely to lose electrons combining with other elements?
the elements which have 1, 2 or 3 electrons in their valence (outermost)shells are most likely to lose electrons compared to the other ones and we name them as metals and alkaline earth metals. these elements want to give their outermost shell electrons to become more stable. because when they give those electrons the next shell under this one which has 8 electrons (2 in some cases such as lithium) becomes the new valence shell so the electron configuration resembles a noble gas.
