How many electrons does barium lose to become a stable octect?
Two electrons.
Why do you think atoms lose electrons to or gain electrons from other atoms?
to become stable
How do then properties of noble gases support this model?
to gain or lose electrons to become stable
Why do Non-metal atoms gain electrons to become an ion?
bcc it's the same
What do atoms other than the Noble Gases have to do in order to become stable?
Atoms gain, lose or share electrons and try to attain noble gas configuration.
Do metals usually gain or loose electrons to be stable?
Metals will LOSE electrons to become stable.
In order to become a chemically stable ion a neutral atom of calcium will?
It would have to lose two electrons.
How electrons will magnesium gain or lose to become stable?
lose 2
How many electrons does barium lose to become a stable octect?
Two electrons.
What are atoms which lose electrons to become stable known as?
cations
Why do you think atoms lose electrons to or gain electrons from other atoms?
to become stable
How many electrons must tantalum need to gain or lose to become stable?
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.
How many electrons would an atom of magnesium have to lose to have a stable octe?
It'll have to lose two to have a stable octet.
Why some atom lose or gain electrons to become ions but noble gas atom never become ion?
Atoms lose or gain electrons to become ions in order to achieve a stable electron configuration, typically through having a full outer shell. Noble gas atoms already have a full outer shell, making them stable and unlikely to gain or lose electrons to become ions. This is known as the octet rule.
How many electrons does Ca lose to become more stable when bonding?
Calcium (Ca) typically loses 2 electrons to become more stable when bonding, as it has 2 valence electrons in its outer shell. By losing these electrons, calcium achieves a full octet, making it more stable.
How many electrons does a magnesium atom need to lose to become stable?
2
Why are what octet's rule?
Octet Rule: In order for atoms to become more stable, they will take electrons, lose electrons, or share electrons so that their outer shell/level will contain eight electrons and be complete.
