Can polyatomic molecules be the same element?
They can be atoms of the same element such as ozone (O3) which is made up of three oxygen atoms, or they can be combinations of two or more different elements. Molecules containing more than two atoms are called polyatomic molecules. Water, yet again, falls into this category.
What are the elements that exist as polyatomic molecules?
definition. …than two atoms are termed polyatomic molecules, e.g., carbon dioxide (CO2) and water (H2O). Polymer molecules may contain many thousands of component atoms.
How are molecules and polyatomic ions alike How are they different?
Polyatomic ions are molecular ions composed of two or more atoms bonded by covalent bonds and acting as a single unit, but unlike molecules, they have a net charge on them.
How do you know if a molecule is polyatomic?
Polyatomic molecules are made up of three or more atoms in a stable structure (bound state). Different molecules are identified by their molecular formula, which reflects the exact number of compositional atoms. The empirical formula and the molecular formula are often, but not always, the same.
What do you mean by polyatomic molecules?
Polyatomic molecules are electrically neutral groups of three or more atoms held together by covalent bonds.
Which one of the following is an example of polyatomic molecule?
or sulphuric acid is an example of a polyatomic molecule in which the total number of atoms present are 7, two atoms of hydrogen, one atom of sulphur and four atoms of oxygen.
What are polyatomic molecules give two examples?
Examples of polyatomic molecules are water (H2O), ammonia (NH3), and carbon dioxide (CO2). The noble gases (such as helium, neon, and argon) exist as single atoms.
How is a polyatomic ion different from a compound?
Polyatomic ions are chemical species having two or more atoms and a net electrical charge. They have either a positive or negative electrical charge. Compounds are chemical species containing identical molecules consist of atoms of two or more chemical elements. They have no net electrical charge.
What is A polyatomic element?
A polyatomic element is a chemical element that naturally exists as a compound molecule containing more than three atoms of the same element. There are only three polyatomic elements in the periodic table, namely- selenium, sulphur and phosphorous.
What is meant by polyatomic molecules?
Is oxygen a polyatomic?
Mercury and oxygen aren’t considered polyatomic ions by themselves, but in the mercury (I) Hg2+2 and peroxide ions O2-2 you indeed have a bond between the same atoms. Comment on Flavian Birgaoanu’s post “Mercury and oxygen aren’t…”
Is sulphur a polyatomic element?
Option 3 is the correct answer: Sulphur is a polyatomic element. The elements which exist as single atom are called monoatomic elements. The elements which exist in atomic pairs bonded to each other are called diatomic elements. The elements which exist as groups of more than two atoms are called polyatomic elements.
Is glucose a polyatomic?
6. Carbon monoxide, CO, is an example of a diatomic molecule, while ammonia and glucose, NH3 and C6H12O6, are examples of POLYATOMIC molecules.
How many different elements are in a polyatomic ion?
two elements
The regular ion has just one element, Chlorine, in it. The polyatomic ion has two elements, Chlorine and Oxygen, in it. A good way to recognize that there are two elements in the polyatomic is to see that there are two capital letters in the ion’s formula.
How do you know if an element is polyatomic?
All the elements on the periodic table start with a capital letter and only some of them have a second letter that is lower case. So if you see two capital letters together in a ion then you will know that it is a polyatomic.
What is the difference between diatomic and polyatomic molecules?
The molecules which is composed by more than two atom this molecule known as polyatomic molecule. The molecule which is composed by only two atoms this molecule is known as diatomic molecule. The chemical species which contain three atoms or more atoms of same or different elements then it is polyatomic.
