Which chemical does not have chemical properties similar to Br?
Helium does not have chemical properties similar to Br (bromine). Helium is a noble gas and is chemically inert, while bromine is a reactive nonmetal.
Which is more reactive At or Br?
Fluorine (F) is more reactive than both Astatine (At) and Bromine (Br) due to its higher electronegativity and smaller atomic size. Astatine is more reactive than bromine due to its lower electronegativity and larger atomic size.
Is selenium or sulfur more reactive?
sulfur is more reactive than selenium
What is the nonmetal in period 4 that is more reactive than selenium?
The nonmetal in period 4 that is more reactive than selenium is sulfur. Sulfur is located above selenium in the same group (group 16) on the periodic table, making it more reactive due to its higher electronegativity and tendency to gain electrons in chemical reactions.
Is helium a reactive non metal?
No. Helium is a nonmetal but it is completely non-reactive.
Is Br or At a more reactive nonmetal?
Bromine would likely be more reactive. Little is known about the chemical properties of astatine because it is very rare and has a short half-life.
What is the reactivity of phosphorus?
phosphorous is a highly reactive nonmetal but fluorine is more reactive
Is Br a metallic element?
No. Br is a nonmetal.
Which chemical does not have chemical properties similar to Br?
Helium does not have chemical properties similar to Br (bromine). Helium is a noble gas and is chemically inert, while bromine is a reactive nonmetal.
Which elements of the halogen family is the most reactive nonmetal?
The most reactive nonmetal is fluorine
What is an reactive nonmetal?
A reactive non metal is an element that can gain the electrons or is more electronegative
What groups of nonmetal is most reactant?
Group 17 or 7-A, the halogens, are the most reactive non-metals.
Which is more reactive At or Br?
Fluorine (F) is more reactive than both Astatine (At) and Bromine (Br) due to its higher electronegativity and smaller atomic size. Astatine is more reactive than bromine due to its lower electronegativity and larger atomic size.
What is an element that is highly reactive gaseous nonmetal?
Chlorine and fluorine, with fluorine more reactive. Some would also include oxygen. (The two remaining halogens are not gaseous at room temperature.)
Is selenium or sulfur more reactive?
sulfur is more reactive than selenium
In period 5 which is a halogen?
Period 5 of the periodic table includes the halogen element bromine (Br). It is a highly reactive nonmetal and exists as a diatomic molecule in its natural state.
What is the nonmetal in period 4 that is more reactive than selenium?
The nonmetal in period 4 that is more reactive than selenium is sulfur. Sulfur is located above selenium in the same group (group 16) on the periodic table, making it more reactive due to its higher electronegativity and tendency to gain electrons in chemical reactions.
