Calcium should lose 2 valence electrons and attain the noble gas configuration of argon with 18 elements.
It must lose two electrons.
Calcium has to lose 2 electrons to form noble gas configuration.
Covalent bonding
Argon (atomic number 18) is the noble gas that is nearest to calcium (atomic number 20)
Calcium will lose two electrons to gain the noble gas configuration of Argon.
It must lose two electrons.
It must give away two valence electrons.
Calcium has to lose 2 electrons to form noble gas configuration.
It must gain one electron to achieve a noble gas electronic structure, just like other halogens.
Calcium is not a noble gas but an alkaline earth metal.
Covalent bonding
Sulfur will gain 2 electrons
Yes it is. Argon (atomic number 18) is the noble gas that is nearest to calcium (atomic number 20)
Argon (atomic number 18) is the noble gas that is nearest to calcium (atomic number 20)
[Ar] 4s2
Calcium will lose two electrons to gain the noble gas configuration of Argon.
Calcium is in group 2 of the periodic table, meaning that it has 2 electrons in its (outer) valence shell. So it 'only' has to lose those 2 electrons from that to acquire Argon's noble gas structure Ar(2,8,8)Ca(2,8,8,2) --> Ca(2,8,8,0)2+ + 2e-
