Chlorine is a yellow-green gas at room temperature. It is an extremely reactive element and a strong oxidising agent: among the elements, it has the highest electron affinity and the third-highest electronegativity on the revised Pauling scale, behind only oxygen and fluorine.

Chlorine gas (Cl2) - Chlorine is the chemical element with the formula Cl2 commonly used as disinfectant. Visit BYJU'S to understand the properties, structure and its uses.

At room temperature, chlorine is a yellow-green gas that is heavier than air and has a strong irritating odor. It can be converted to a liquid under pressure or cold temperatures. Chlorine is mainly used as bleach in the manufacture of paper and …

The gas is greenish yellow in color and the liquid is clear amber. The data on physical properties of chlorine as determined by different investigators show some variations. Atomic and Molecular Properties. Atomic Symbol - Cl; Atomic Weight - 35.453; Atomic Number - 17; Molecular Weight of Cl2 - 70.906; Chemical Properties

Chlorine gas poisoning is an illness resulting from the effects of exposure to chlorine beyond the threshold limit value. Acute chlorine gas poisoning primarily affects the respiratory system, causing difficulty breathing, cough, irritation of the eyes, …

Mar 21, 2025 · Chlorine molecules are composed of two atoms (Cl 2). Chlorine combines with almost all the elements, except for the lighter noble gases, to give chlorides; those of most metals are ionic crystals, whereas those of the semimetals and nonmetals are predominantly molecular.
