Type your answer here... The number of valence electrons in calcium is 20, because it's almost the same thing as it's atomic number.

What is the valence number for calcium phosphate?
Calcium has valence of 2, forming the calcium ion Ca2+. The phosphate ion, PO43- contains five valent phosphorus and divalent oxygen along with three extra electrons. Compounds do not have a valence, atoms have a valence.
How many valence electrons are in the polyatomic ion HPO4 -2?
Hydrogen has 1 valence electron, phosphorus has 5 valence electrons, and oxygen has 6 valence electrons. So, if you totaled all of the valence electrons in the ion HPO42- you'd get 1 + 5 + 6 X 4 + 2 = 32. However, you should realize that the term "valence electron" really only applies to individual atoms, not compounds. The only electrons one would concern themselves with in the HPO42- ion are the 2 that make it an ion.
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+.
When a calcium atom loses its valence electrons the ion formed has an electron configuration that is the same as an atom of?
Argon. Calcium has the electron configuration 1s2 2s2 2p6 3s2 3p6 4s2, and when it loses its valence electrons (the outermost 4s2 electrons) it has a configuration identical to argon. If you don't know about sublevels, then disregard that. Calcium has a configuration of 2-8-8-2, and when it loses its 2 valence electrons, it has a configuration identical to argon in the ground state. Hope that cleared it up
How many valence electrons are in calcium plus chlorine?
the valence of CaCl2 is 2 because its not necessary that CaCl2 is always attached in hydrated form...... the basic thing which u study in your school classes that the outermost shell of both the element must be completed. so cacl2 has the valency of 2 because ca is electropositive. think it
Number of valence electrons calcium lose?
The calcium atom (Ca) loses two valence electrons to form a calcium ion (Ca2+).
How many electrons must calcium gain or lose to have 8 valence electrons and what charge of the ion will it make?
Calcium has two valence electrons and needs to lose both to achieve a stable electron configuration, resulting in 8 valence electrons in the nearest noble gas configuration (argon). By losing these two electrons, calcium forms a cation with a charge of +2, resulting in a Ca²⁺ ion.
How many neutrons are in calcium oxide?
Depends on what you mean by number of electrons. Calcium has 20 electrons and oxygen has 8 electrons for a total of 28 electrons. But if you mean how many VALENCE electrons, then the calcium has 2 and the O has 6 for a total of 8 valence electrons.
How many pairs of valence electrons exist on a I ion?
A I ion, specifically iodide (I⁻), has a total of 8 valence electrons. In its neutral state, iodine has 7 valence electrons, but it gains one additional electron when it forms an ion, resulting in 8. Since each pair of valence electrons consists of 2 electrons, there are 4 pairs of valence electrons in an iodide ion.
How many valence electrons are in chloride?
Chlorine has 7 valence electrons. A chloride ion has 8.
How many electrons will calcium gainer lose when forming an ion?
Calcium (Ca) is an alkaline earth metal that typically loses two electrons to achieve a stable electron configuration when forming an ion. This results in the formation of a calcium cation (Ca²⁺). By losing these two valence electrons, calcium attains a noble gas configuration similar to argon.
What is the valence number for calcium phosphate?
Calcium has valence of 2, forming the calcium ion Ca2+. The phosphate ion, PO43- contains five valent phosphorus and divalent oxygen along with three extra electrons. Compounds do not have a valence, atoms have a valence.
Can calcium become stable by losing 1 electron?
Calcium loses its two valence electrons to become Ca 2+ ion.
Is calcium with a plus 1 charge a ion?
Yes - but it is rare - usually has a + 2 charge
The ion ICl4- has how many valence electrons?
if you are asking about ICl4- ion then there are 28 valence electrons and 8 binding ones.total of 36 electrons
How many electrons does the most common ion of calcium Ca have?
The most common ion of calcium (Ca) is the calcium ion (Ca²⁺), which forms when calcium loses two electrons. Calcium has an atomic number of 20, meaning it has 20 electrons in its neutral state. Therefore, the Ca²⁺ ion has 18 electrons.
How many numbers of electrons grained or lost for calcium?
Calcium typically loses 2 electrons to achieve a stable electron configuration, forming a Ca2+ ion. This results in a full outer energy level (valence shell), similar to the noble gas configuration of argon.
