Very, tho reactivity decreases down the group
It is 3rd member of Halogens family the Bromine.
chemically active means an active chemical.
No uranium is not chemically active
carbon is chemically active
Halogens are very chemically reactive elements and noble gases are practically unreactive.
Oxygen is a rather chemically active element.
Noble gases have completely filled orbitals and hence are generally chemically inert. Halogens are highly reactive as they need one more electron to complete octet.
Halogens are very reactive both physically & chemically than that of inert gases ,as halogens have valency 1.
The most active metals are alkali metals. The most active nonmetals are halogens.
An element is chemically active till it does not attain an inert gas configuration.
The most chemically active metallic element is hydrogen.
Halogens or Group VII-A elements...
they are all non metals and when chemically joined will form salts
Active. VERY active. Sometimes, EXPLOSIVELY active.
Metals in group one are chemically active as compared to the elements in group three and two. Elements like sodium, potassium, chlorine and fluorine are some of the chemically active elements.
Covalent Bond. Chemically Active. The only elements that are inert are group 18, or 8A.
The Halogens, they have a full valence electron shell.
The most chemically active of all the elements is fluorine. It is considered the element with the most electronegativity in the table.
Metals that are chemically active have low electronegativity because matals have a weak attraction to electrons.
The most reactive of the nonmetals are the halogens (especially fluorine and chlorine) and oxygen.
The most active nonmetals are located in group 17. They are the halogens.
When it reacts easily with other elements or compounds.
Fluorine is more active.
the group 7 halogens from the top downward Florine>Chlorine>Bromine>iodine
It is fluorine. Fluorine is part of the halogens they are very active nonmetals.
They will be in the same group (for example the halogens and noble gases). Look at the periodic table.
Fluorine, F, is the most reactive element of all.
Oxygen is chemically active because it reacts with other chemicals such as hydrogen to form water.
At room temperature the lighter halogens, F, Cl are diatomic gases, Br is a liquid, I is a solid. All of the halogens are colored and toxic. The noble gases are all colorless odorless non chemically toxic monoatomic gases. (Radon is radioactive).
This is the halogens family: F, Cl, Br, I.
i am pretty sure that when an atom is chemically active its outer valence shell is not full meaning it is able to form different types of bonds with different elements.
Metals are particularly likely to combine chemically with the halogens you listed, but I will add that almost every element on the periodic table (with the exception of the noble gases) will combine with at least some of the halogens.
Francium is a very radioactive and very chemically reactive chemical element.
Gold is active, or at least not inert. Only the noble gases are inert.
Noble gases are chemically inert.
Chemically, actinium is similar to lanthanum. Actinium react with halogens (F, Cl, Br, I), oxygen, sulphur, etc.
Uranium is a metal and behaves chemically in a way similar to the lanthanides and transition metals. It reacts readily with oxygen and halogens.
one electron away from stability therefore highly reactive
group 1 (alkali metals) and group 17 (halogens)
This is the halogens group: F., Cl, Br, I, At.
Argon is a chemically inactive non metal.
Fluorine is the more reactive.
The halogens are are the most active nonmetals. There're 5 non-metallic elements in the halogen family. The term "halogen" means "salt-former" & compounds containing halogens are called "salts".They are: Fluorine, Chlorine, Bromine, Iodine & Astatine
A chemical reaction - with oxygen, water, acids, bases, halogens, carbon, hydrogen, etc.
The most chemically active element is the halogen known as fluorine. Be
Heat, Pressure, and Chemically active fluids.
Alkali metals are the most reactive metals.
