What are the physical properties of sulfur?
Pure sulfur is a tasteless, odourless, brittle solid that is pale yellow in colour, a poor conductor of electricity, and insoluble in water. It reacts with all metals except gold and platinum, forming sulfides; it also forms compounds with several nonmetallic elements.
What are the chemical properties of sulfur?
Sulfur Chemical Properties Sulfur is an odorless, tasteless, light yellow solid. It is a reactive element that given favorable circumstances combines with all other elements except gases, gold, and platinum. Sulfur appears in a number of different allotropic modifications: rhombic, monoclinic, polymeric, and others.
How many types of sulphur are there?
Sulfur has 23 known isotopes, four of which are stable: 32S (94.99\%±0.26\%), 33S (0.75\%±0.02\%), 34S (4.25\%±0.24\%), and 36S (0.01\%±0.01\%).
What elements can bond with sulfur?
Two hydrogen (H) atoms can bond with one sulfur (S) atom, making the formula H2S, also known as hydrogen sulfide.
Is reaction with sulfur a physical or chemical property?
Unlike physical properties, chemical properties can only be observed as the substance is in the process of being changed into a different substance. A chemical change is also called a chemical reaction. Zinc and sulfur are two elements that undergo a chemical. reaction when heated to from the compound zinc sulfide.

What are the three forms of sulphur?
Allotropes of Sulphur and Sulphur Dioxide
- 1.1 (i) Rhombic sulphur or α-Sulphur.
- 1.2 (ii) Monoclinic sulphur or β-Sulphur.
- 1.3 (iii) Plastic sulphur or δ-sulphur.
What type of solid is sulphur?
Sulphur is a multivalent non-metal, abundant, tasteless and and odorless. In its native form sulphur is a yellow crystalline solid. In nature it occurs as the pure element or as sulfide and sulfate minerals.
What molecules are sulfur found in?
The amino acids cysteine, methionine, homocysteine, and taurine contain sulfur, as do some common enzymes, making sulfur a necessary component of all living cells. Disulfide bonds between polypeptides are very important in protein assembly and structure.
Is Melting sulfur a chemical or physical change?
Remember, the appearance of matter changes in a physical change, but its chemical identity remains the same. Melting solid sulfur into liquid sulfur. This is an interesting example since the state change does cause a color change, even though the chemical composition is the same before and after the change.
