Question

Name one solid one liquid and gaseous nonmetal

Answer 1

Nonmetals :

• Nonmetals are electronegative elements that share or receive electrons in chemical reactions.
• Non-metals are elements that have a high band gap (activation energy) and are hence poor conductors of heat and electricity.
• Furthermore, nonmetals lack luster and have four or more electrons in their valence shell.
• Twenty elements have been discovered that exhibit non-metallic characteristics.
• Non-metals are elements on the periodic table's right side.
• These exist in all three states of matter

1. Solid non-metal – Carbon ($\mathrm{C}$)
2. Liquid non-metal – Bromine ($\mathrm{Br}$)
3. Gaseous non-metal – Chlorine ($\mathrm{Cl}$)
