The halogens are those elements in group XVII of the periodic table, and include fluorine, chlorine, bromine, iodine, and astatine, the latter of which is a radioactive element of no industrial importance. The physical properties of the halogens are shown. They indicate an almost perfect ...
The physical properties of halogens are as follows. The halogens may exist as solid, liquid, or gas at room temperatures. They dissolve in water but solubility decreases as we go down the group. The solutions of halogens are acidic in nature They show a regular increase in melting ...

To determine which halogen always shows only one oxidation state, we can follow these steps: Step 1: Identify the HalogensThe halogens are a group of elements in Group 17 of the periodic table, which include:- Fluorine (F)- Chlorine (Cl)- Bromine (Br)- Iodine (I)- Astatine (At) Ste...
The elements in Group 1 are called ___. A. alkaline earth metals B. halogens C. noble gases D. alkali metals 相关知识点: 试题来源: 解析 D。解析:文中提到“the elements in Group 1, also known as the alkali metals”,即第一族的元素也被称为碱金属。
Any of a group of five nonmetallic elements with similar properties. The halogens are fluorine, chlorine, bromine, iodine, and astatine. Because they are missing an electron from their outermost shell, they react readily with most metals to form salts. The halogens are located in the column ...
Step 1: Understand the HalogensThe halogens are a group of elements in Group 17 of the periodic table, which include fluorine (F), chlorine (Cl), bromine (Br), and iodine (I). Step 2: Analyze ElectronegativityElectronegativity is the tendency of an atom to attract electrons in a chemic...
