General Science (Easy) Chemistry

An atom of iron is …. Times as heavy as atom of hydrogen.

1638

238

- An iron atom's approximate atomic weight is 56 unified atomic mass units (u).

- A hydrogen atom's approximate atomic weight is 1 unified atomic mass unit (u).

- Iron is approximately 56 times heavier than hydrogen.

- Comparing atomic weights:

- Option 1: 23 times is incorrect for iron vs. hydrogen.

- Option 2: 1638 times is significantly excessive.

- Option 3: 55 times is very close to the correct ratio.

- Option 4: 238 times is much higher than the actual difference.

Correct Answer: Option 3 - 55
