Anything in column 15 - nitrogen and phosphorus are two examples.
Tantalum needs to lose 2 electrons to become stable. Tantalum has 73 protons, so losing 2 electrons will give it a full outer shell of 71 electrons, which is the most stable configuration for the element.
An oxygen atom needs 2 electrons to become stable because it has 6 electrons in its outer shell and it needs a total of 8 electrons to have a full valence shell. By gaining 2 electrons, oxygen can achieve a full outer shell and become stable.
5 valence electrons because it needs to gain 3 electrons in order to become 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.
The element fluorine typically forms one single bond because it has seven valence electrons and needs one more electron to complete its octet and become stable.

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.
An oxygen atom needs 2 electrons to become stable because it has 6 electrons in its outer shell and it needs a total of 8 electrons to have a full valence shell. By gaining 2 electrons, oxygen can achieve a full outer shell and become 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)
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.
5 valence electrons because it needs to gain 3 electrons in order to become stable
Just one. To become stable, it needs eight electrons; a full outer shell.

8 electrons are needed in the outer level to become a stable element.Writing A Bohr Atomic Model (LEVELS):1st level- Up to 2 electrons2nd level- Maximum of 8 electrons3rd level- 18, 8, or less electrons4th-7th level- 32, 18, 8, or less electrons
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.
A chlorine atom needs one additional electron in order to become stable.
