How many electrons are needed to be gained or lost in aluminium to achieve stable electron configuration?
Only three electrons.
Why does oxygen form with an ion with -2 charge?
A lone, neutral oxygen atom has 6 electrons in its outer shell, but this is not very stable, so oxygen will tend to gain 2 more electrons in order to get a full, stable shell of 8 electrons.
How many additional electrons is an oxygen atom able to attract?
An oxygen atom is able to attract 2 additional electrons to complete its valence shell and achieve a stable octet configuration. This is because oxygen has 6 valence electrons and needs a total of 8 electrons for stability.
How many electrons are gained in Se?
Selinium is a non metal element. There are 34 electrons in a single atom.
Oxygen needs how many more valence electrons?
Oxygen has six valence electrons and needs two more to fill its outer shell and achieve a stable octet configuration. This is why oxygen typically forms two bonds with other elements, such as in water (H₂O) or carbon dioxide (CO₂). By gaining or sharing two additional electrons, oxygen can attain a stable electronic configuration.
How many electrons must the oxygen atom lose to be stable?
Oxygen wants to gain 2 electrons, so its charge would be 2-, because electrons have a negative charge.
When an oxygen atom becomes an oxide ion it has a charge of -2 why?
When an oxygen atom gains two electrons to become an oxide ion, it fills its outer energy level and achieves a stable electron configuration known as the octet rule. This results in a complete set of eight electrons, giving it a full valence shell and a charge of -2.
How many electrons were gained or lost in oxygen?
In oxygen, each atom gains two electrons to achieve a stable electron configuration through forming two covalent bonds. This means that each oxygen atom gains two electrons to reach a full valence shell.
How many electrons are in the anion of chloride?
The anion of chloride (Cl⁻) has 18 electrons, as it has gained one electron to achieve a stable electron configuration. Chloride has 17 electrons in its neutral state, but when it gains an electron, it becomes Cl⁻ with 18 electrons.
What causes an atom to be stable?
An atom becomes stable by gaining or loosing electrons.
How many electrons can oxygen lend?
Oxygen can lend two electrons to form a stable compound. Oxygen typically forms bonds by accepting two electrons to complete its outer shell and achieve a stable electron configuration.
Does oxygen atoms become more stable or less stable when oxygen forms compounds?
Oxygen atoms become more stable when they form compounds because they are able to complete their valence shell by sharing electrons with other atoms. This allows them to achieve a full outer electron shell and become more like the stable noble gases.
How is the valency of oxygen two?
The valency of oxygen is two because oxygen typically forms covalent bonds by sharing two electrons with other atoms. This allows oxygen to achieve a stable octet configuration, which is energetically favorable.
When sulfur becomes sulfide it is?
When Sulphur becomes Sulphide, it becomes negatively charged with 2 extra negative charges. It is S2-
How many electrons are needed to be gained or lost in aluminium to achieve stable electron configuration?
Only three electrons.
How many electrons are gained when going from Al to Al3 plus?
-3 electrons are gained,i.e,3 electrons are lost by Al and 3 electrons are gained by the other atom nearby.
Why does oxygen form with an ion with -2 charge?
A lone, neutral oxygen atom has 6 electrons in its outer shell, but this is not very stable, so oxygen will tend to gain 2 more electrons in order to get a full, stable shell of 8 electrons.
