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
