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.
A calcium atom has two valence electrons.
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.
The element that has a mass number of and two valence electrons is an isotope of calcium.
its in column two on the periodic table, so therefor it has two valence electrons .
Calcium phosphate is solid.
A calcium atom has two valence electrons.
To calculate the number of moles in 150g of calcium phosphate, you need to first determine the molar mass of calcium phosphate (Ca3(PO4)2), which is 310.18 g/mol. Then, divide the given mass of calcium phosphate by its molar mass to get the number of moles. In this case, 150g / 310.18 g/mol ≈ 0.48 moles.
When calcium combines with phosphate, it forms calcium phosphate. The chemical formula for calcium phosphate is Ca3(PO4)2.

Calcium phosphate is composed of calcium and phosphate ions. The ratio of these ions can vary, leading to different types of calcium phosphate compounds such as hydroxyapatite and tricalcium phosphate.
The element that has a mass number of and two valence electrons is an isotope of calcium.
its in column two on the periodic table, so therefor it has two valence electrons .
Calcium phosphate is the main mineral from which bone is comprised.
Calcium phosphate is a salt, an inorganic compound.
Calcium phosphate is solid.
Calcium phosphate is a compound composed of calcium cations and phosphate anions. It is not an element, as elements are composed of only one type of atom.
