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.

Is helium a Halogens or a Nobel Gas?
Helium is definitely a NOBLE(Inert) gas.
What state of matter do halogens naturally occur in?
They do Occur in SOLID,LIQUID and GAS
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.
How does the state of matter of halogens change as you move from top to bottom on the element table?
it goes from gas to solid
Are all halogens gases at room temperature?
no bromine is liquid and iodine is solid at room temp
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
Is helium a Halogens or a Nobel Gas?
Helium is definitely a NOBLE(Inert) gas.
Does halogens have high or low reactivity?
Halogens have highreactivity.
What does cl2 strand for?
Cl2 stands for Chlorine.It is a gas of halogens.
What is reactive gas?
The Halogens Fluorine and Chlorine are both reactive gases.
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 state of matter do halogens naturally occur in?
They do Occur in SOLID,LIQUID and GAS
What are the common properties of noble gases and halogens?
they dont have any common properties except that when halogens gain one electron, they achieve the electronic configuration of the nearest noble gas.
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.
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.
