32
PO^4-3
Phosphate has 5 valence electrons
Oxygen has 6(4)=5+24=29+3=32
and then you just add three more valence electrons to get a grand total of 32.
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.
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.
There are 32 valence electrons in the Lewis structure of the sulfate ion (SO3^2-), which consists of one sulfur atom and three oxygen atoms. Sulfur contributes 6 valence electrons, and each oxygen contributes 6 valence electrons, totaling 32 valence electrons in total.
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 carbonate ion, CO3 2-, has a total of 24 valence electrons. This is because there are three oxygen atoms, each contributing 6 valence electrons, and a charge of 2- indicates the addition of 2 electrons to account for the overall charge on the ion.
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.
Chlorine has 7 valence electrons. A chloride ion has 8.
The ICl4- ion has 36 valence electrons. Iodine contributes 7 valence electrons and each chlorine atom contributes 7 valence electrons, totaling 36 valence electrons in the ICl4- ion.
The phosphate ion is a polyatomic ion with a total charge of -3. This means it has gained 3 electrons to achieve an overall negative charge, so it has a total of 30 electrons.
Arsenide ion has 3 valence electrons. Arsenic, the element from which arsenide ion is derived, is in group 15 of the periodic table, so it has 5 valence electrons. When it forms an ion with a charge of -3, it gains 3 electrons to achieve a full octet.
A magnesium atom has 2 electrons in its valence shell. A magnesium ion has 8 electrons in its valence shell.
A sulfur atom has 6 valence electrons, while a sulfide ion has 8 valence electrons because it gains two electrons to achieve a stable electron configuration.
A neutral iodine atom has 7 electrons in its valence shell. When iodine forms an ion with a charge of -1, it gains an extra electron, making a total of 8 electrons in its valence shell.
A chlorine atom has 7 valence electrons, as it is in group 17 of the periodic table. A chloride ion has 8 valence electrons, as it gains an additional electron to achieve a full octet and a stable electron configuration.
Sulfur (S) has 6 valence electrons. The S2- ion gains two electrons, bringing the total to 8 valence electrons.
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.
