The halogens or halogen elements are a series of nonmetal elements from Group 17 IUPAC Style (formerly: VII, VIIA) of the Periodic Table, comprising fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). The artificially created element 117, provisionally referred to by the systematic name ununseptium, may also be a halogen. The group of halogens is the only periodic table group which contains elements in all three familiar states of matter at standard temperature and pressure.
What else can I help you with?
What state of matter do halogens naturally occur in?
Halogens naturally occur in the gaseous state. Examples of halogens are fluorine, chlorine, bromine, iodine, and astatine.
How many electrons do halogens have to lose or gain to achieve a stable noble gas electron configuration?
They have to gain 1 electron. Halogens have 7 electrons in their valence shell and noble gasses have 8.
Is helium a Halogens or a Nobel Gas?
Helium is a Noble Gas. It belongs to the group 18 (VIIIa) of the periodic table.
Elements in Group 17 are all called?
Halogens Apex ;)
Halogens combine with most metals to form salts?
That is correct. Halogens like chlorine, bromine, and iodine readily react with metals to form ionic compounds called salts. For example, sodium chloride (table salt) is formed when sodium metal reacts with chlorine gas.
Are fluorine and chlorine a noble gas or halogen?
halogens
What group achieves the electron configuration of a noble gas by gaining one electron?
All halogens have 7 valence electrons. They gain one electron and achieve noble gas electronic configuration

An element that is a very reactive gas is most likely a member of the what?
Chlorine is the most reactive gas element. Chlorine is in the halogen family.
What is the gas with a mass number of nineteen?
The atomic mass 19 is for fluorine, the ist member of halogens it exists as F2,a diatomic gas.
Is helium a Halogens or a Nobel Gas?
Helium is a Noble Gas. It belongs to the group 18 (VIIIa) of the periodic table.
What is the pH halogens?
Halogens do not have a specific pH as they are elements on the periodic table and do not directly contribute to the acidity or basicity of a solution. However, when halogens react with water, they can form acidic solutions. For example, when chlorine gas dissolves in water, it forms hydrochloric acid, which can lower the pH of the solution. Overall, the pH of a solution containing halogens would depend on the specific halogen present and its reactivity with water.
Does halogens have high or low reactivity?
Halogens have high reactivity because they have a strong tendency to gain an electron to achieve a stable electron configuration. This reactivity decreases as you move down the group from fluorine to iodine.

Is a noble gas the same as a halogen?
No. Halogens are group 17 elements. Noble gases are group 18 elements.
