(A) Neon
B
(B) Calcium
C
(C) Nitrogen
D
(D) Silicon
Answer
(A) Neon
Explanation
Solution
Explanation:
Neon is a chemical element with the symbol Ne and atomic number 10. It is a noble gas. Neon is a colourless, odourless, inert monatomic gas under standard conditions, with about two-thirds the density of air. It was discovered (along with krypton and xenon) in 1898 as one of the three residual rare inert elements remaining in dry air after nitrogen, oxygen, argon and carbon dioxide were removed.Hence, the correct option is (A).
