What is a mnemonic sentence to memorize the SEVEN diatomic elements?

A. "Hiking Over New Mountains, Braving Icy Winds."
B. "Have No Fear Of Ice-Cold Water."
C. "Hugs On Neon Beds In Cozy Winters."
D. "Help Our Friends, Never Ignore Compounds."

Answer 1

The mnemonic sentence 'Have No Fear Of Ice-Cold Water' helps to memorize the seven diatomic elements: Hydrogen, Nitrogen, Fluorine, Oxygen, Iodine, Chlorine, and Bromine.

Step-by-step explanation:

To memorize the seven diatomic elements, we can use mnemonic devices. The correct mnemonic sentence that includes all the initials for the seven diatomic elements (Hydrogen, Oxygen, Nitrogen, Bromine, Iodine, Chlorine, Fluorine) is:

Option B: "Have No Fear Of Ice-Cold Water."

• H - Hydrogen (H₂)
• N - Nitrogen (N₂)
• F - Fluorine (F₂)
• O - Oxygen (O₂)
• I - Iodine (I₂)
• Cl - Chlorine (Cl₂)
• Br - Bromine (Br₂)

Each letter in the sentence corresponds to the first letter of each element in its diatomic form. This mnemonic is a tool to help recall the particular elements that are naturally found in pairs.
