When is an element stable?
For an element to be stable, it must have a full outer shell (valence shell) of electrons. An element with a full outer shell of electrons will act like its nearest noble gas and be stable. Most elements require 8 valence electrons to be stable, however H needs 2.
How many valance electrons does nitrogen?
5 valence electrons because it needs to gain 3 electrons in order to become stable
How many electrons must tantalum need to gain or lose to become stable?
It needs to lose 3.
How many electrons does potassium need to gain or loose to become more stable?
Potassium (K), an Alkali Metal in Group 1 with atomic number 19, has a single valence electron in its outermost shell. Therefore it only needs to lose one electron in order for the element to become stable.
What does the fluorine atom do to become stable unreactive?
A stable arrangement of electrons in the outer shell is 8, but fluorine has only 7, that is why it is unstable. It needs another electron, desperately. No other element craves electrons as strongly as fluorine does.
Is the krypton element stable or unstable?
no it is not stable bcoz if an atom needs to be stable it needs to have 8 electrons in the valency (outermost) shell,where as a krypton has only 2 in its valency electron.
When is an element stable?
For an element to be stable, it must have a full outer shell (valence shell) of electrons. An element with a full outer shell of electrons will act like its nearest noble gas and be stable. Most elements require 8 valence electrons to be stable, however H needs 2.
Is silicon or aluminum more stable?
both Actually aluminum is a little unstable. Its electronic configuration is 2,8,3. To be stable an element needs to have a full outer electron shell so to become stable Aluminium needs to lose 3 electrons to become 2,8 so it will have a full outer shell (8 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 valance electrons does nitrogen?
5 valence electrons because it needs to gain 3 electrons in order to become stable
In chlorine the outer energy level contains 7 electrons To attain stable state the chlorine atom needs to gain how many electrons?
Just one. To become stable, it needs eight electrons; a full outer shell.
How many electrons must tantalum need to gain or lose to become stable?
It needs to lose 3.
How many electrons does potassium need to gain or loose to become more stable?
Potassium (K), an Alkali Metal in Group 1 with atomic number 19, has a single valence electron in its outermost shell. Therefore it only needs to lose one electron in order for the element to become stable.
Do oxygen compounds become more stable or less stable when oxygen forms compounds?
Oxygen has six valence electrons, which means that it needs to gain two to become stable. it takes much more energy for oxygen to lose its 6 valence electrons than it would be to gain 2. When atoms form compounds, they become stable.
How does sulfur forms its ion?
ions are formed based upon the valence electrons of the element and if the element is a metal or a nonmetal. S has 6 valence electrons and needs 2 more to be stable. it is a nonmetal. therefore, taking on 2 electrons gives S a -2 charge
What is The number of electrons that neon needs to gain to achieve stability?
Neon is already a stable element with a full outer electron shell, so it does not need to gain any electrons to achieve stability. Neon has 10 electrons in total, with a full valence shell of 8 electrons. Therefore, it is already in a stable configuration.
What does the fluorine atom do to become stable unreactive?
A stable arrangement of electrons in the outer shell is 8, but fluorine has only 7, that is why it is unstable. It needs another electron, desperately. No other element craves electrons as strongly as fluorine does.
