Front

What is the general trend of reactivity in Group 17 elements?

Back

Reactivity increases as you move up the group.

Front

What are the physical states of halogens at room temperature?

Back

Halogens exist in different states: Fluorine and Chlorine are gases, Bromine is a liquid, and Iodine is a solid.

Front

What is the significance of electronegativity in chemical bonding?

Back

Electronegativity determines how strongly an atom attracts electrons in a bond.

Front

What is the common oxidation state of halogens in compounds?

Back

-1 is the most common oxidation state for halogens.

Front

What are some common uses of halogens?

Back

Halogens are used in disinfectants, bleaches, and in the production of pharmaceuticals.

Front

What is the difference between ionic and covalent bonds?

Back

Ionic bonds involve the transfer of electrons, while covalent bonds involve the sharing of electrons.

Front

What is the role of halogens in organic chemistry?

Back

Halogens are often used to modify organic compounds, affecting their reactivity and properties.
