How many electrons must be gained or lost for calcium to attain a noble-gas electron configuration?
two electrons lost
How many electrons must be gained or lost for calcium to attain a noble gas electron configuration?
Ca needs to lose 2 electrons to become Ca+2
Does Chlorine (Cl) reacts by losing electrons?
Chlorine is a non metal and it reacts by gaining electrons rather than losing inorder to attain a stable electron configuration of the noble gases.
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).
What has a pseudo-noble-gas electron configuration?
The pseudo noble-gas electron configuration has the outer three orbitals filled, the s, p and d- s2p6d10 (18 electrons total) and so is fairly stable. Elements that attain this electron configuration are at the right side of the transition metals (d-block). Br-, I-, Se2-
How many valence electron does Ca lose or gain to attain noble-gas electron configuration?
Calcium loses two electrons to obtain a noble-gas electron configuration.
How many electrons must be gained or lost for calcium to attain a noble-gas electron configuration?
two electrons lost
Metals tend to gain electrons to attain the electron configuration of noble gases?
true, just not for Boron witch tries to gain 6 electrons for a stable arrangement
How many electrons does a carbon atom need to gain in order to attain a noble gas electron configuration?
4
How does an element in group 2 attain a stable electron configuration?
It loses 2 electrons and becomes a +2 ion.
How many electrons does nitrogen give up to achieve noble gas electron configuration?
nitrogen should give 5 electrons (or better gain 3 electrons) to attain noble gas configuration.
When an aluminum atom reacts so as to attain a noble gas electron confuration?
aluminium should lose three electrons to attain noble gas configuration
How is the electron configuration of Sulfur consistent with the formation of Na2S and SF6?
Sulfur has six valence electrons and can therefore attain an inert gas configuration in two different ways: by accepting two electrons to attain the electron configuration of argon or donating or sharing six electrons to attain the electron configuration of neon. In combination with the much less electronegative element sodium, sulfur accepts one electron from each of two sodium atoms to form the ionic compound Na2S, but in combination with the more electronegative element fluorine, sulfur shares its six valence electrons with each of six fluorine atoms to form six polar covalent bonds with fluorine.
How many electrons must Kr lose to attain a noble gas electron configuration?
Krypton is a noble gas and need not lose electrons. It is already stable.
How many electrons does silicon need to gain a noble electron gas configuration?
An atom of silicon needs to gain 4 electrons in its 3p sublevel to attain the noble gas electron configuration of argon, the noble gas in period 3 of the periodic table.
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 (+).
Atoms attain the same electron configuration as of noble gases by?
Either by losing or gaining electrons (and forming ionic compounds) or by sharing of electrons (and forming covalent compounds).
