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 elements form polyatomic molecules?

The most common polyatomic elements are the oxygen family: oxygen, ozone, nitrogen, carbon dioxide, and water. When atoms of different elements combine to form a molecule, the atoms may share one or more electrons to form covalent bonds.

Can molecules have two different elements?

Heteronuclear molecules All other diatomic molecules are chemical compounds of two different elements. Many elements can combine to form heteronuclear diatomic molecules, depending on temperature and pressure. Examples are gases carbon monoxide (CO), nitric oxide (NO), and hydrogen chloride (HCl).

How are molecules and polyatomic ions alike How are they different?

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 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 are the selection rules for polyatomic molecule?

a. The selection rules for rotational transitions of a linear polyatomic molecule are ΔJ = 0, ±1, and Δℓ = 0, ±1; where J is the total angular momentum quantum number excluding nuclear spin and ℓ is the vibrational angular momentum quantum number which arises in degenerate bending vibrational states.

Which of the following pairs of elements have polyatomic molecules?

The elements which exist as groups of more than two atoms are called polyatomic elements. Chlorine (Cl2), Nitrogen (N2) and Hydrogen (H2) are diatomic gases. But sulphur exists as S8 and hence it is polyatomic. Selenium (Se8), Ozone (O3) and Phosphorous (P4) some other polyatomic elements.

What are the examples of polyatomic?

Well-known examples of such polyatomic ions are the sulfate ion (SO42–), the hydroxide ion (OH–), the hydronium ion (H3O+), and the ammonium ion (NH4+).

Do molecules have to be the same element?

A molecule is defined as two or more atoms of the same element different element that are bound together. A molecule may be homonuclear, which means, it consists of atoms of one chemical element, as with oxygen (O2); or it may be heteronuclear, a chemical compound composed of more than one element, as with water (H2O).

Can have atoms of either the same element or different elements?

A molecule consists of two or more atoms of the same element, or different elements, that are chemically bound together.

What is the difference between polyatomic ion and polyatomic molecule?

Answer. Answer: 1) polyatomic ions mean more than two atoms having charge but a polyatomic molecule means may be combination of two or more than two atoms having charge. 2) polyatomic molecules are electrically neutral while polyatomic ions have a net charge.

How do polyatomic ions differ from simple ions?

Main Difference – Monatomic vs Polyatomic Ions This is the main difference between monatomic and polyatomic ions. Monatomic ions are composed of a single atom whereas polyatomic ions are composed of two or more atoms per ion. These ions can be either cations or anions.
