6NiO + 4 ClF 3 → 6 NiF 2 + 3 O 2 + 2 Cl 2 AgCl + ClF 3 → AgF 2 + ClF + 1/ 2 Cl 2. ClF 3 is used to produce uranium hexafluoride: U + 3 ClF 3 → UF 6 + 3 ClF. With phosphorus, it yields phosphorus trichloride (PCl 3) and phosphorus pentafluoride (PF 5), while sulfur yields sulfur dichloride (SCl 2) and sulfur tetrafluoride (SF 4).
A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
Chlorine is a chemical element; it has symbol Cl and atomic number 17. The second-lightest of the halogens, ... (F: 3.98, Cl: 3.16, Br: 2.96, I: 2.66), and is less ...
Each distinct atomic number therefore corresponds to a class of atom: these classes are called the chemical elements. [5] The chemical elements are what the periodic table classifies and organizes. Hydrogen is the element with atomic number 1; helium, atomic number 2; lithium, atomic number 3; and so on.
The halogens (/ ˈ h æ l ə dʒ ə n, ˈ h eɪ-,-l oʊ-,-ˌ dʒ ɛ n / [1] [2] [3]) are a group in the periodic table consisting of six chemically related elements: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and the radioactive elements astatine (At) and tennessine (Ts), though some authors [4] would exclude tennessine as its chemistry is unknown and is theoretically expected to ...
A mnemonic is a memory aid used to improve long-term memory and make the process of consolidation easier. Many chemistry aspects, rules, names of compounds, sequences of elements, their reactivity, etc., can be easily and efficiently memorized with the help of mnemonics.
Cl F 3 O 2: Molar mass: 124.44 g·mol −1 Appearance colorless gas Density: 5.087 g/L Melting point: ... ClF 3 + O 2 → ClO 2 F 3. Physical properties
