Electrons that are held most loosely in an atom are called what?
Valence electrons are the electrons that are held most loosely in an atom. These electrons are involved in chemical bonding and determine the reactivity of an element.
What element has 118 and 8 valence electrons?
Ununoctium has 118 electrons including 8 valence electrons.
What is the number of valence electrons of iodine?
Iodine has 7 valence electrons like the other halogens.
What element has 8 valence electrons and is in the gaseous sate at room temperature?
Neon.
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.
How many valence electrons are in the element Neon?
There are 8 valence electrons for neon.
How many electrons can an atom hold in its outermost level?
The number of valence electrons depends on the element and it could have 1 to 8 valence electrons.
What is odd element in the noble gases?
Helium is odd as it has 2 valence electrons while others have 8 valence electrons.
What is the maximum number of valence electrons that an atom can have excluding hydrogen helium and beryllium?
The maximum number of valence electrons will vary from element to element ranging from 1 to 8.
How do valence electrons tell you what elements will bond together?
Atoms only bond if it helps them achieve their goals of having 8 valence electrons. That is why noble gases do not bond; they already have 8 valence electrons.
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 are found in a krypton atom?
There are 8 Valence Electrons.
What rule is used to predict the number of electrons that must be lost or gained in order to achieve stability?
For doing so, firstly the electronic configuration of the element is written.Then it is seen how many electrons does the element has in its valence shell.The max. no. of electrons that can be present in the valence shell is 8. So, if the element has less than 4 electrons in the valence shell, then it looses them to form stable ion and if it has more than 4 electrons, it must gain 8-no. of valence electrons to form stable ion. If the element has 4 valence electrons, then it shares them with other atoms to form compounds.
What is the number of valence electrons of iodine?
Iodine has 7 valence electrons like the other halogens.
What element has 118 and 8 valence electrons?
Ununoctium has 118 electrons including 8 valence electrons.
Electrons that are held most loosely in an atom are called what?
Valence electrons are the electrons that are held most loosely in an atom. These electrons are involved in chemical bonding and determine the reactivity of an element.
What is the total number of electrons in the outermost energy level?
The velence electron will vary for element to element and can have 1 to 8 valence electrons.
