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.

∙ 10y ago8 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.

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 electrons will Calcium gain in forming an ion?
None.Calcium loses 2 electrons to form an ion.
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.
How many valence electrons are there in the Lewis structure of the sulfate ion so32?
32
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 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.
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 a chlorine atom and a chloride ion?
There are 7 valence electrons in chlorine atom and 8 valence electrons in chloride ion.
How many valence electrons are present in a chloride ion?
A chloride ion has 18 electrons, giving it a valence of -1.
How many electrons will be in the valence shell of a iodine ion?
Iodine atom has 7 valence electrons, whereas Iodide ion has 8 valence electrons.
How many valence electrons in arsenide ion?
Three electrons
How many valence electrons are in chloride?
Chlorine has 7 valence electrons. A chloride ion has 8.
Can calcium become stable by losing 1 electron?
Calcium loses its two valence electrons to become Ca 2+ ion.
How many valence electrons does magne sium have?
A magnesium atom has 2 electrons in its valence shell. A magnesium ion has 8 electrons in its valence shell.
How many electrons are in a phosphorus Ion's outermost energy level?
Phosphorus forms P3- ion and it has 8 valence electrons (5 valence electrons from phosphorus and three from the charge).
