Lithium can gain and lose electrons because it has three electrons in its outermost energy level. It can lose one electron to achieve a stable configuration like a noble gas, or gain seven electrons to complete its outer shell. This ability allows lithium to form different ions with different charges.
What else can I help you with?
How many electrons does oxygen have to gain in order to achieve a noble-gas electron configuration?
Lithium has one valence electron. It is much easier for an atom to lose one electron than gain seven more. Lithium looses this one electron to achieve a full outer shell (the next inside shell is full).
Would sulfur gain or lose an electron when forming an ion?
Sulfur can both gain and lose electrons when forming ions. It can gain two electrons to form a sulfide ion (S2-) or lose two electrons to form a sulfide ion (S2+).
Does sn gain or lose electrons?
Sulfur typically gains electrons to form a stable electron configuration. It can gain up to two electrons to achieve a full valence shell of eight electrons.
Do nonmetals lose electrons when they react?
Nonmetals tend to gain electrons when they react, rather than lose them. This is because they have fewer electrons in their outer shell and they have a higher tendency to gain electrons to achieve a stable electron configuration.
How many electrons is needed to gain or lose to fill the outer shell?
It depends what element for example, lithium would need to gain 7 electrons or lose 1 so that the outer-most shell is full. However, elements like neon (which is a noble gas) don't need to gain or lose any electrons since the outer shell is already filled. It depends on it's place in the periodic table of the elements.
Would atom with an atomic number of 3 lose or gain electrons?
Lithium loses electrons.
How many electrons does lithium gain?
Lithium loses one electron when it reacts
How many electrons does lithium lose or gain to achieve a stable octet configuration?
Lithium is in group 1 of the Periodic How_many_electrons_must_the_lithium_atom_give_up_to_become_stable, so it must lose one electron for it to attain a full outermost energy level and become stable.The charge will then be positive (+).
How many electrons must be gained or lost for each of the following to achieve a noble gas electron configuration Lithium atom Bromine atom Barium ion Helium atom?
sodium must lose 1 electron, helium is a noble gas it is in group 8 check your periodic table, sufide ion must gain 2 electrons
When compounds gain electrons they lose or gain energy?
Lose
When atoms lose or gain electrons they from?
When atoms lose or gain electrons, they form ions. These are charged particles.
Will Se lose or gain electrons and how many?
Se will gain electrons
The lose of electrons from a molucule is called?
Lose electrons is oxidation. To gain electrons is reduction.
How many electrons does Si gain or lose?
Silicon (Si) can gain or lose 4 electrons. It can either gain 4 electrons to have a stable octet configuration or lose 4 electrons to achieve a stable configuration.
Do metasls gain electrons?
If you mean Metals... No, they do not gain electrons, they actually lose electrons because it is a lot easy for them to lose them so they can gain stability much faster.
What happens in terms of electrons when lithium reacts with oxygen?
Oxygen is more electronegative than lithium, a metal. Oxygen has a tendency to gain two electrons so it will bond with two lithium atoms which have a tendency to donate one valence electron for bonding. Li2O
Does copper gain or lose electrons?
it loses electrons
