Why is a hydroxide ion a polyatomic ion?

OH - is Polyatomic . Hydroxide (OH - ) contains both an atom of oxygen (O) and hydrogen (H). Many ions are from only ONE atom or element, but since OH - contains two separate elements, it is polyatomic.

What is a polyatomic ion?

They are electrically charged species composed of more than one atom Examples: . Monoatomic: Cl - chloride , S 2- sulfide, Na + sodium . Polyatomic: NH 4 + ammonium, CO 3 2- carbonate Edit: It is a tightly bound group of atoms that has a positive or negative charge and behaves (MORE)

What are polyatomic ions?

A charged ion that is composed of two or more atoms covalently bonded. No: Each chloride ion contains only one atom.

What are the polyatomic ions?

polyatomic ions are those ions which carry more than one atom,we can say that a group of atoms having single charge( which may be positive or negative) are polyatomic ions.

Molar mass of a polyatomic ion?

To find the molar mass of a polyatomic ion, you simply find the molar mass of every element that makes up the ion and add them together. Do not forget to multiply the molar mass if there are multiple atoms. . For Example: Find the molar mass of NO3 . NO3 is made up of Nitrogen and Oxygen . Nitrog (MORE)

Which ions in the table are polyatomic ions?

it is sulfate, sulfite and many more.... Answer: Common Polyatomic Ions: -1 Charge: · Chlorate: CO 3 -1 · Chlorite: ClO 2 -1 · Cyanide: CN -1 · Dihydrogen Phosphate: H 2 PO 4 -1 · Ethanoate: CH 3 COO -1 · Hydroxide: OH -1 · Hydrogen Carbonate: HCO 3 -1 (MORE)

How do you write the formula when ions are Polyatomic ion?

U just need to remember the overall charge of the polyatomic ion for example no3- that's enough In case of ionic compound For example magnesium ion and nitrate ion Magnesium is 2 positive charge while nitrate ion is 1 negative charge.(in order to achieve octet structure) To form ionic compound for (MORE)

How can you tell if a ion is polyatomic ion?

If it contains a number in its formula (such as in peroxide, O 2 - ) it is polyatomic as this means there are more than one atom of the same type. If it contains more than one element, which you would find if there is more than one capital later. (such as in hydroxide, OH - ). If both are true, (MORE)

How do you write the formula for a compound containing a polyatomic ion?

Generally, polyatomic ions all have charges, or valency electrons which act as the charges as a whole. They are considered as a whole category of compounds in chemistry which have a combined charge. You should look up list of polyatomic ions for Google, if you need to learn them. To write the formul (MORE)

What is a polyatomic ion and name five common polyatomic ions?

Poly means many. So a polyatomic ion is an ion made up of more than one atom. Simple examples come from common acids and alkalis. Sulphuric acid (H2SO4) forms the ions H+ (monoatomic) and SO42- (polyatomic). Nitric acid gives the ion NO3-. Hydroxides give us the OH- ion. Carbonates give (MORE)

How do you write a formula for polyatomic ions?

Write the symbol of the cation first, than the anion . State the combining capacity for each element over each of the ions . Use the 'cross over' method and reduce the numbers to the lowest ration (without changing the formula for the ion) e.g. Na + SO 4 2- -> Na 2 SO 4

Which polyatomic ion has 4 oxygens?

The three most common such ions probably are sulfate, with the formula SO 4 -2 , chromate, with the formula CrO 4 -1 , and perchlorate, with the formula ClO 4 -1 .

Polyatomic ions are usally charged?

Ions are charged by definition: they are atoms or molecules that have either lost or got one or more electrons so to have a positive or negative charge. Examples are Trifluoromethan ion CF3- Trifluoroacetic acid ion CF3COO- Nitrogen ion NH2-

Is sodium perbromate a polyatomic ion?

Sodium perbromate is not a polyatomic ion. It is an ionic compound formed by combining sodium (Na +1 ) ions with perbromate ions (BrO4 -1). Perbromate by itself would be a polyatomic ion.

How are formulas written for ionic compounds with polyatomic ions?

Formulas for ionic compounds with polyatomic ions are written just like normal ionic compounds would be written like. For example, lets say your ionic compound is Ammonium nitrate. The formula for ammonium is NH 4 and the formula for nitrate is NO 3 . The chemical formula of Ammonium nitrate will t (MORE)

What is the formula for the polyatomic ion NaNO3?

Basically, there are two ions in the compound NaNO 3 , the Sodium ion(Na + ) and the Nitrate ion(NO 3 1- ). So, this compound is called Sodium nitrate. Polyatomic ions are ions that consist of more than one atom in it. So here, the nitrate ion is the polyatomic ion, while the sodium ion is the (MORE)

What is anion cation and polyatomic ion?

Anion: a negative ion Cation: a positive ion Polyatomic Ion: a molecular ion which is a charged species (ion) composed of two or more atoms covalently bonded.

What are descriptions of a polyatomic ion?

The word prefix poly- means many. So with the word polyatomic you have multiple atom types. So a polyatomic ion is an ion with multiple types of atoms in it. A polyatomic ion is composed of two or more atoms covalently bonded or of a metal complex that can be considered as acting as a single unit in (MORE)

How do write the formula for a compound containing a polyatomic ion?

Make sure you are familiar with the most common polyatomic ions. Look at the locations of the elements on the Periodic table. Atoms in the same column as each other tend to exhibit similar characteristics, including the number of electrons the elements would need to gain or lose to resemble the near (MORE)
