Chlorine Atoms

Chlorine Atoms (Cl)

Chlorine atoms react with aromatic hydrocarbons, but only at a significant rate with those having saturated side chains from which the chlorine atom can abstract a hydrogen or unsaturated side chains to which it can add. For example, the rate constant for the Cl atom reaction with benzene is 1.3 × 10⁻¹⁵ cm³ molecule⁻¹ s⁻¹ (Shi and Bernhard, 1997). On the other hand, the rate constants for the reactions with toluene and p-xylene are 0.59 × 10⁻¹⁰ and 1.5 × 10⁻¹⁰ cm³ molecule⁻¹ s⁻¹, respectively (Shi and Bernhard, 1997), and that for reaction with p-cymene is 2.1 × 10⁻¹⁰ cm³ molecule⁻¹ s⁻¹ (Finlayson-Pitts et al., 1999). Hence reactions of aromatic hydrocarbons with chlorine atoms will be significant primarily for those species having reactive groups attached to the ring.

What type of atom is chlorine?

Chlorine is a chemical element with the symbol Cl and atomic number 17. The second-lightest of the halogens, it appears between fluorine and bromine in the periodic table and its properties are mostly intermediate between them. Chlorine is a yellow-green gas at room temperature.

Is chlorine atom stable?

Chlorine atoms have two electrons in the inner ring, then eight electrons in the second ring, then seven electrons in their outer ring. This means that they are not stable, but they only need to add one electron to the outer ring to fill it up, and then the chlorine atom will be stable

Is chlorine an atom or molecule?

With seven electrons in its outermost orbit–one electron short of a “stable eight”– the element chlorine exists in nature as a diatomic molecule. This arrangement allows two chlorine atoms to share their outermost orbit electrons, achieving stability, compared to the single atom.

Is chlorine a diatomic element?

Diatomic elements are pure elements that form molecules consisting of two atoms bonded together. There are seven diatomic elements: hydrogen, nitrogen, oxygen, fluorine, chlorine, iodine, bromine. … For example, oxygen can exist as the triatomic molecule, ozone.

Why does chlorine have 2 atoms?

Chlorine lacks one electron in its outer shell to be balanced. … Chlorine gas Cl2, like other gases – Nitrogen (N2), Oxygen (O2), and Hydrogen (H2) form diatomic molecules in nature. A single molecule of the gas contains two atoms that are linked by a covalent bond, hence the Cl2

What is the bonding in chlorine?

Chlorine is a non-metal. A chlorine atom has 7 electrons in its outer shell. … with other chlorine atoms. One pair of shared electrons form a single covalent bond.

How many bonds does a chlorine atom form?

A chlorine atom has 7 electrons in its valence shell—it needs 8 to complete it. Two chlorine atoms can share 1 electron each to form a single covalent bond. They become a Cl₂ molecule. Oxygen can also form covalent bonds, however, it needs a further 2 electrons to complete its valence shell (it has 6).
