How many electrons does barium lose to become a stable octect?
Two electrons.
Have two valence electrons and get to a stable electron configuration by using two electrons?
You can achieve a stable electron configuration by using two electrons by forming a covalent bond with another atom that also has two valence electrons. In this way, each atom can share its valence electrons to achieve a full outer shell and achieve stability.
How many electrons would an atom of carbon need to have to be a negative ion?
There are six electrons in two shells.In order to stable carbon, it take electrons from nearest noble gas to stable the carbon.It order to stable carbon it gain -4 electrons from the nearest noble gas Neon.
An atom is stable when its outermost orbit is?
An atom is stable when its outermost orbit, or valence shell, is complete with the maximum number of electrons it can hold according to the octet rule. This typically means having eight electrons for most elements, except for hydrogen and helium which only need two electrons in their outer shell to be stable.
How many electrons are transfered in calcium?
Calcium typically loses two electrons to reach a stable electron configuration. Its atomic number is 20, so it has 20 electrons in its neutral state. When it forms Ca2+ ions, it loses two electrons to have a stable configuration with a full outer shell.
Is an atom stable if it has two electrons in the third shell?
No - it would want to lose these two 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 xenon gain or lose electrons to be a stable octet?
Neither. It has a stable octet in its ground state.
How many electrons does selenium need to lose or gain to be stable?
Selenium needs to gain two electrons to achieve a stable electron configuration. By gaining two electrons, selenium will have a complete outer energy level (valence shell), which is the most stable configuration for an atom.
Are free electrons stable?
No. Free electrons are not stable.
How many electrons does an atom need in its outer energy level to be stable?
Most atoms require eight electrons in the outer shell to be stable. The exception is atoms that are only filling the s1 orbital, which becomes stable with only two electrons.
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.
How many electrons would an atom of carbon need to have to be a negative ion?
There are six electrons in two shells.In order to stable carbon, it take electrons from nearest noble gas to stable the carbon.It order to stable carbon it gain -4 electrons from the nearest noble gas Neon.
How many electrons does a stable calcium ION have?
A stable calcium ion has lost two electrons, resulting in a total of 18 electrons. Calcium typically has 20 electrons in its neutral state, but when it loses two electrons to form a Ca2+ ion, it maintains stability by having a full outer electron shell.
How many valance electrons does helium have?
Helium has two valence electrons. It is the only noble gas not to have eight valence electrons. Helium has the electronic configuration 1s2.The Noble gases have eight valence electrons in their outer shell.
