Gain two electrons to have the electron configuration as Argon
Calcium loses two electrons to obtain a noble-gas electron configuration.
nitrogen should give 5 electrons (or better gain 3 electrons) to attain noble gas configuration.
All should lose 2 electrons to attain the nearest noble gas configuration
aluminium should lose three electrons to attain noble gas configuration
It should loose 2 electrons to become a noble gas.
Atoms lose or gain or share electrons and tend to attain noble gas configuration
Calcium loses two electrons to obtain a noble-gas electron configuration.
Calcium's electron configuration is [Ar] 4s2. To attain a noble gas configuration, calcium must lose 2 electrons to have the same electron configuration as argon, 4s2 3d10.
Phosphorus should gain 3 electrons and form P3- ion to attain a noble gas configuration
nitrogen should give 5 electrons (or better gain 3 electrons) to attain noble gas configuration.
All should lose 2 electrons to attain the nearest noble gas configuration
aluminium should lose three electrons to attain noble gas configuration
It should loose 2 electrons to become a noble gas.
Metals like sodium,potassium get noble gas configuration by losing electrons. Elements like nitrogen,oxygen get noble gas configuration by gaining electrons. Halogens get noble gas configuration by sharing electrons.
Yes. If there are 1 to 3 valence electrons in an atom, then generally those elements will lose these electrons to attain noble gas configuration. If there are 5 to 7 valence electrons, then generally those elements will gain electrons to attain noble gas configuration.
Magnesium (Mg) has 12 electrons. To attain a noble gas configuration, Mg would need to lose 2 electrons to have the same electron configuration as a noble gas (like neon). This would result in Mg forming a +2 ion.
Krypton is a noble gas and need not lose electrons. It is already stable.
