How are halogens like metals?
Halogens are not like metals. Halogens are elements missing one electron for full valency.
The most reactive group of nonmetals is the?
Group 17 (known as Halogens)
What is Oxidation number of halogens?
Halogens typically have an oxidation number of -1 in compounds because they have seven valence electrons and need to gain only one electron to achieve a full octet. Exception: in compounds with oxygen or other halogens, halogens may have positive oxidation numbers.
What is the characteristics about the outer electron shells of halogens?
The outer electron shells of halogens have seven electrons, making them one electron short of a full outer shell. This makes halogens highly reactive as they tend to gain an electron to achieve a stable electron configuration. Halogens are located in Group 17 of the periodic table.
Why are halogens the most stable ionic charge?
Halogens are the most stable in their group because they have a full outer shell of electrons when they gain one electron to form a 1- charge. This full outer shell allows halogens to achieve the electron configuration of a noble gas, making them more stable.
How many electrons do the halogens have in their outer most energy level?
The halogens have 7 electrons in their outer shell desparate to gain the 1 electron to make a full shell of 8 electrons.
Which family of elements is the most reactive nonmetal family?
The most reactive family of nonmetals is the halogen family.
Why are halogens not monatomic?
Halogens are not monatomic because they exist naturally as diatomic molecules in their elemental form. For example, fluorine exists as F2, chlorine as Cl2, bromine as Br2, and iodine as I2. This diatomic nature is due to the atoms forming a more stable arrangement by sharing electrons and achieving a full outer electron shell.
The oxidation number of halogens is?
Most common is -1. But halogens (except fluorine) are known to exhibit oxidation numbers upto +7 in their compounds.
What is the relationship between halogen and a noble gas?
atomic number fall into groups and periods....groups two of which are halogens and noble gases... means halogens and noble gases are related to each other by groups... hope i helped...
What type of anions are formed in the halogens?
Halogens typically form negatively charged anions called halides. These halide ions have a full outer electron shell and are stable due to gaining one electron to achieve a full outer shell.
What is the valency of halogens and what does it mean?
The valency of halogens is 1, meaning they can form one bond with another element. This valency indicates how many electrons halogens need to gain in order to achieve a full outer shell and become stable.
