Explain why neon, Ne does not react with other elements.
Answer:
The neon atom has a stable octet arrangement of electrons
Question 4:
Compare the boiling point of helium and argon. Explain.
Answer:
The size of atoms increases when going down the group because the number of filled electron shells increases. The melting point and boiling point of argon are higher than those of helium. The size of the atom increases when going down the group because the number of filled electron shells increases / atomic size of argon is larger compared to helium atom. The attraction force between argon atoms are stronger compared to helium atoms. More heat energy is needed to overcome the attraction force between argon atoms.
