Calcium atom will generally lose two electrons to form Ca2+ ions. Calcium will not accept (gain) electrons.
Calcium loses its two valence electrons to become Ca 2+ ion.
two electron should be lost
It must gain two electrons.
The calcium atom (Ca) loses two valence electrons to form a calcium ion (Ca2+).
Calcium loses 2 valence electron to become ionized.
Beryllium can lose its two valence electrons.
It is going to lose electrons
Atoms with eight valence electrons usually do not gain or lose electrons. Atoms with one, two, or three valence electrons will lose electrons.
P has 5 valence electrons so it can gain 3 electrons or lose 5 electrons to have a full valence shell.
Phosphorus wants to gain three electrons to have 8 valence electrons.
Bromine must gain one electron
This is a metal so it will lose its valence electrons.
it will lose 2 electrons
atoms lose, gain, or share valence electrons to have 8 valence electrons.
As a general rule, the noble gases do not lose or gain valence electrons because in most reactions they are considered inert.
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.
This atom gain two electrons.
Ca loses electrons.
Like all metals calcium will lose electrons.
8 valence electrons. It originally has 20 electrons (inclusion of 2 valence electrons). the ion form of calcium will lose the two electrons, thus losing the outermost valence shell. the next shell will contain the full 8 valence electrons.
It will lose 2 electrons.
Sulfur must gain two electrons.
