What is the example of polyatomic atom?
Polyatomic ions are ions which consist of more than one atom. For example, nitrate ion, NO3-, contains one nitrogen atom and three oxygen atoms. The atoms in a polyatomic ion are usually covalently bonded to one another, and therefore stay together as a single, charged unit.
What molecules are polyatomic?
Polyatomic molecules are electrically neutral groups of three or more atoms held together by covalent bonds. Molecules are distinguished from ions by their lack of electrical charge.

Is P4 polyatomic?
S8 and P4 are polyatomic molecules.
What are polyatomic molecules give 2 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.
Is NO2 a compound?
Oxides of nitrogen are a mixture of gases that are composed of nitrogen and oxygen. Two of the most toxicologically significant compounds are nitric oxide (NO) and nitrogen dioxide (NO2).
How are polyatomic ions similar to a molecule?
Similarly, we can think of a polyatomic ion as a molecule that has been ionized by gaining or losing electrons. In a polyatomic ion, the group of covalently bonded atoms carries a net charge because the total number of electrons in the molecule is not equal to the total number of protons in the molecule.
How many electrons does nitrogen have in the 2p orbital?
It therefore has five valence electrons in the 2s and 2p orbitals, three of which (the p-electrons) are unpaired. It has one of the highest electronegativities among the elements (3.04 on the Pauling scale), exceeded only by chlorine (3.16), oxygen (3.44), and fluorine (3.98).
Why does a polyatomic ion carry a net charge?
In a polyatomic ion, the group of covalently bonded atoms carries a net charge because the total number of electrons in the molecule is not equal to the total number of protons in the molecule. When drawing Lewis dot structures, the overall charge on a polyatomic ion is equal to the sum of the formal charges on each atom in the ion.
When is a diatomic molecule composed of the same element?
If a diatomic molecule is composed of the same element it is known as a homo nuclear and if it is composed of two different elements it is known as hetero nuclear. What is a Polyatomic Ion? A polyatomic ion is also known as a molecular ion that is composed of two or more covalently bonded atoms.
