What is unique about halogens?
Halogens are unique because they are very reactive non-metals. "Halogens" is a Greek word meaning salt producers.
Are halogens the basis for all fossil fuels?
No. The halogens are fluorine, chlorine, bromine, iodine, and astatine.
Does halogens have high or low reactivity?
Halogens have highreactivity.
What halogen is most likely to react?
The reactivity of halogens decreases down the group, which means Fluorine is the most reactive halogens as it is the most electronegative elements among the halogens, and also the Periodic Table.
What is the correct list of elemental families in order going from left to right?
Alkali metals, transition metals, halogens or Transition metals, halogens, noble gases or Alkali earth metals, halogens, noble gases
What trends the periodic table should be expected as the atomic number decreases in the halogens?
Halogens with lower atomic number are more reactive and less dense. Also iodine is solid, bromine liquid and the first halogens are gases.
What can dubnium bond with?
Only four compounds with Cl and Br were obtained up today.
The most reactive group of nonmetals is the?
Group 17 (known as Halogens)
What is the characteristic property of the halogens?
Halogens are group seven on the Periodic Table, this means they take electrons during bonding as opposed to giving them. Halogens are often used for cleaning and disinfecting, most notably in pools. They are also poisonous and were introduced into warfare in the first world war. Halogens are common in acids such as hydro-CHLORIC acid.
What elements has the highest first ionization energy?
Fluorine has the largest first ionization energy among the halogens.
What element has a higher first ionization energy then carbon?
Halogens, specially fluorine
Elements in Group 17 are all called?
Halogens Apex ;)
What are halogens and where are they located?
Halogens are in Group 7
Why are halogens known as salts?
Halogens are not salts but they are chemical elements; halogens can form salts reacting with metals.

Halogens are radioactive or not?
No, halogens are reactive however and can be dangerous.
Are halogens reactive?
Yes, halogens are extremely reactive.
