It needs to lose to in order to have the same number of outer electrons as Argon. The Noble gas configuration of [Ar]4s2 confirms this.

Would you expect calcium to gain or lose electrons in a chemical reactions?
Like all metals calcium will lose electrons.
For calcium ca write the numbers of electrons it must gain or lose to have 8 vlance electrons then calculate the charge of the ion that would form?
Ca must lose 2 electrons to have a complete 3n shell, which has 8 valence electrons. The ion would have a charge of 2+: Ca^2+.
Which compounds are tetravalent?
Tetravalent means having 4 valence electrons. The elements in the 14th group are tetravalent. They do not lose or gain electrons. they gain electrons.
How many valence electrons does nitrogen need to be full?
Nitrogen has five valence electrons as a neutral atom, but it is shooting for eight. So it needs to gain three more electrons.
How much electrons would bromine have to gain or lose to get 8 valence electrons?
It'll have to gain one to have a stable octet.
Will the valence electrons of calcium give or take away electrons?
Calcium atom will generally lose two electrons to form Ca2+ ions. Calcium will not accept (gain) electrons.
How many valence electrons must calcium lose or gain to have 8 valence electrons?
It loses 2 electrons to obtain the argon configuration of 8 valence electrons.
What is the number of electrons a calcium atom must gain or lose to have 8 valence electrons?
two electron should be lost
How many valence electrons must sulfur gain or lose to get 8 valence electrons?
It must gain two electrons.
Would calcium gain or lose electrons?
calcium loses two electrons, becoming a +2 ion
How many electrons does phosphrous have to gain or loose to have 8 valence?
P has 5 valence electrons so it can gain 3 electrons or lose 5 electrons to have a full valence shell.
How many electrons phosphorus must gain or lose to have 8 valence electrons?
Phosphorus wants to gain three electrons to have 8 valence electrons.
How many electrons must phosphorus p gain or lose to have 8 valence electrons?
Phosphorus wants to gain three electrons to have 8 valence electrons.
How will atoms with 5 valence electrons achieve a full set of valence electrons?
They will gain 3 electrons from something with 3 valence electrons.
Can nonmetals gain electrons to fill their valence shells?
Yes, nonmetals generally gain electrons to fill valence shells.
In a reaction how many valence electrons will probably gain two electrons or share two covalent bonds?
In a reaction u need two valence electrons to gain or share two valence electrons.
Would you expect calcium to gain or lose electrons in a chemical reactions?
Like all metals calcium will lose electrons.
