Atoms always want to have 8 electrons in their outer shell. Calcium only has two so its easier for it to give those away than to aquire 6 more. When these electrons are gone, that "shell" no longer exists so its got 8.

How many electrons does the calcium atom lose?
I believe it is 2, seeing it is a metal, and has 2 valence electrons. Correct me if I'm wrong, I don't have my periodic table with me (Calcium -> Ca?).
How many electrons would calcium have to lose or gain to have to have 8 valence electrons?
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.
Why does calcium lose 2 electrons?
The ionic charge is +2: The atom has equal numbers of positively charged protons and negatively charged electrons. The number of protons is the same in the atom and the ion, but in the ion two negative charges have been lost, so that the ion has a net charge of +2.
How do lithium and fluorine become stable together?
lithium donates the electron in its outer orbital to fluorine which then has a completed outer shell
Why might a calcium atom want to lose the two electrons in its outer orbital?
Having just 18 electrons make Calcium nobel.
How many electrons does the calcium ion lose from an atom?
It loses 2 electrons.
What is the name of electrons in the outer most shell that an atom can gain lose or share with another atom?
Electrons in the outer most shell are called Valence Electrons.
Number of valence electrons calcium lose?
The calcium atom (Ca) loses two valence electrons to form a calcium ion (Ca2+).
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 will calcium gain or lose to fill its outer shell?
A calcium atom will normally lose its two valence electrons, which have principal quantum number 4, to a more electronegative atom when forming a compound. When this happens, the already filled electron shell with principal quantum number 3 becomes the outer shell of the resulting calcium cation, and this cation has the electronic structure of the noble gas preceding calcium in the periodic table, neon
How many electrons will a calcium atom Ca lose in order to get a noble gas configuration?
Calcium will lose two electrons to gain the noble gas configuration of Argon.
How many electrons does a aluminum atom lose to form an ion?
an aluminum atom will lose the 3 electrons on its outer shell 2 for an aluminum ion.
Why can an atom lose electrons easily?
Atoms do not always lose electrons. Electrons can be gained too. Atoms always try to have their outer most shell filled, and some atoms such as ones of potassium can easily lose an electron rather than gain an electron. So it would lose an electron to a different atom so that it would have a full outer shell and the other atom would also have a full outer shell.
If an atom has 3 electrons how many electrons are in the outer shell Will it be more likely to acquire or lose an electron?
If an atom has three electrons, it will have one valence electron (valance = outer shell). It will be more likely to lose an electron than gain one, since it has only one to lose, but seven to gain.
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 electrons will the sodium atom need to lose to get a full outer shell?
Just one.
