Wouldn't the oxygen have fulfilled the octet rule? Why would it form another bond with H? with the H? 1) O is stable and has its octet completed in H 2 O but it is one of the highly the H + , and oxygen forms a co-ordinate bond with H + , thus forming H 3 O + . Octet rule isn't

How Do You Know What Kind of Ion a Metalloid Forms?

How do you know if a metalloid will form a positive or negatively charged ion? Is it just any metalloid on the right of the line forms negatively charged ions? Sorry, very basic question but I can't if a metalloid will form a positive or negatively charged ion? Is it just any metalloid on the right

Question:How are hydrochloric acid and sulphuric acid different? similar? in terms of ions

Answers:Hydrochloric acid = HCl A hydrogen ion has a charge of + and a chlorine ion had a charge of -. Sulphuric acid = H2SO4 Let's look at the sulfate molecule first...a sulfate ion has a charge of 2-. And as stated earlier, a hydrogen ion has a charge of +. That's why there's a subscript of 2 for hydrogen...two hydrogen ions are needed to balance with one sulfate ion which has a charge of 2-. I hope that's what you were looking for.

Question:All I'm given is this: A solution contains 0.010 M CaCl2. calculate the molarity of the ions in solution. The ionic strength of the solution, the activity coefficient of the calcium ion and its activity. I'm confused on how to solve this. We're given a sample calculation but it is not a very thorough explanation.

Answers:CaCl2 breaks down into Ca+ and 2Cl- in a solution which total 3 ions. so if there are 0.010 M (= mols/L) of cacl2 then multiply by 3 to give you the molarity of toatal ions. Mathematically: (0.010mols CaCl2 / L)(3 ions / CaCl2) = 0.030 mols/L (= M) ions. good luck!

Question:If Ion forms when an atom looses or gain electron and cation forms when an atom looses one or more electron, isn't both are the same. look!! 1)Ion=atom-1electron 2)Ion=atom+1electron 3)Cation=atom-1electron 4)cation=atom-more than 1electron Isn't 1=3 ?? I'm confused right now, I really need to understand this concept!!

Answers:if an atom LOSES an electron it means that a negative charge is being withdrawn from the ion..thus it becomes more positive..if the charge of the resulting ion is positive it is called a CATION. on the other hand, if an ion GAINS an electron..it means that the ion becomes more negative since it induces a negative charge (electron is negative) thus making the charge of the ion also negative..this is now called the ANION :D
