Question

What are the elements of group $\mathrm{VII}$ called?

Answer 1

Halogen:

• Group $\mathrm{VII}$ elements are known as halogens.
• They are located in the second from the right vertical column of the periodic table.
• In nature, halogens do not exist in their elemental state.
• Chlorine $\left(\mathrm{Cl}\right)$, bromine $\left(\mathrm{Br}\right)$, and iodine $\left(\mathrm{I}\right)$ are the three most prevalent Group $\mathrm{VII}$ elements.
• Group $\mathrm{VII}$ elements create salts when they react with metals.
• The halogens have middling melting temperatures and low boiling points.
• Fluorine has the lowest melting and boiling points.
• As we progress through the group, the melting and boiling points rise.

Elements of Halogens:

• Fluorine $\left(\mathrm{F}\right)$
• Chlorine $\left(\mathrm{Cl}\right)$
• Bromine $\left(\mathrm{Br}\right)$
• Iodine $\left(\mathrm{I}\right)$
• Astatine $\left(\mathrm{At}\right)$
