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.
A phosphorus atom surrounded by four oxygen atoms is commomly called a?
A phosphorus atom surrounded by and chemically bonded to each of four oxygen atoms is commonly called a "phosphate ion" if it is a triply charged anion or a "phosphate group" if present in a covalently bonded compound.
What is the correct Lewis electron-dot diagram for an atom of sulfur- 33?
..:O:.. l ..:O-S-O:" l ":O:" (SO4)2- 32 total electrons: 6 per atom plus 2grrr it wont get the spaces right. its 4 oxygen around a sulfur, all single bonds. each oxygen has 6 extra electrons around it
What is the correct Symbols for sulfur ion with 18 electrons?
The correct symbol for a sulfur ion with 18 electrons would be S^2-. This means the ion has gained 2 extra electrons, giving it a total of 18 electrons and a 2- charge.
What is the ion notation for sulfur with 18 electrons?
The ion notation for sulfur with 18 electrons would be S2-. This means that sulfur has gained two extra electrons to achieve a full octet, giving it a -2 charge.
Why is phosphate negatively charged due to its structure?
Phosphate is negatively charged due to its structure because it contains oxygen atoms that have extra electrons, giving the molecule an overall negative charge. This makes phosphate an important component of many biological molecules and processes.
What is the Lewis structure for the oxide anion?
The oxide anion, O²⁻, has a Lewis structure that shows the oxygen atom with six valence electrons. To represent the anion, two additional electrons are added, giving it a total of eight electrons. The structure features the oxygen atom surrounded by three lone pairs of electrons and a full octet, indicating its stable charge of -2. There are no bonds in the oxide anion; it is simply represented as O²⁻ with the two extra electrons.
Why does F3- not form a Lewis structure?
F3- does not form a Lewis structure because F (Fluorine) has 7 valance electrons. F3 totals 21 valance electrons +1 for the - charge for a total of 22. However when you attempt to bond 3 F atoms together in a Lewis structure there is only space for 20 valance electrons. This is not a problem for atoms like Br or I because they can fit those extra electrons in the near by d orbital. Fluorine being a period 2 element does not have a d orbital and can not form a F3- Lewis structure. -JCS
How many electrons must be used in the Lewis structure of the hydroxide ion OH-1?
Oxygen contains 6 Protons, Hydrogen contains 1 Proton, and the total charge is -1. Therefor, the number of Electrons is 8.
What is the process for drawing a CO Lewis dot structure?
To draw a CO Lewis dot structure, first determine the total number of valence electrons for carbon and oxygen. Carbon has 4 valence electrons and oxygen has 6. Next, place the least electronegative atom (carbon) in the center and connect it to the more electronegative atom (oxygen) with a single bond. Fill the remaining valence electrons around the atoms to satisfy the octet rule. Carbon should have 8 electrons and oxygen should have 8 electrons. If there are extra electrons, place them on the central atom.
What is the Lewis dot structure for pentaiodide?
The Lewis dot structure for pentaiodide (I5-) consists of five iodine atoms bonded together in a linear fashion, with one extra electron to form a negative charge on the molecule. Each iodine atom will have seven valence electrons, with three lone pairs and a single bond to the adjacent iodine atom.
What is the Lewis structure of hso5 and how does it represent the bonding and electron distribution within the molecule?
The Lewis structure of HSO5- shows sulfur in the center with one hydrogen atom, four oxygen atoms, and one negative charge. The sulfur atom forms bonds with each oxygen atom, and there are lone pairs of electrons on the oxygen atoms. This structure represents covalent bonds between sulfur and oxygen atoms, with the negative charge indicating an extra electron in the molecule.
Lewis structure for NO2-1?
The dot structure for nitrogen dioxide starts with a N atom in the center with a double bond to the O to the left and a single bond to the right. The doubly bonded O has two pair of dots, and the single bonded O has three pair. Finish with a single dot on the N atom.
What is the Lewis dot structure for I3 plus?
I -> 7e- O(3x) -> 3(6e-) = 18e- Since its an IO3- it has an extra electron Total electrons = 18e- + 7e- +1e- = 26e- I is the Central Atom Each O has a single bond with 6 valance electrons and I and 2 Structure : Trigonal Pyramidal
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 does ICl4 have?
Valency of carbon is 4.Valency of chlorine is 1
What is term for a semiconductor that contains extra electrons?
N-type semiconductor contains extra electrons.
