Answer:

a) Yes, two atoms of a similar element are identical.

b) No, water cannot stay as a liquid at 0 degrees or below, as water freezes.

a liquid at 0 degrees or below, as water freezes.HOPE THESE ANSWERS HELPED YOU :) :) :)

Hey mate,

1. No. Although two such atoms are essentially chemically identical (they will chemically react in the same way), they are not completely identical. ... The nucleus of an atom contains neutrons and protons bonded tightly together. The same chemical element can have a different number of neutrons and still be the same element.
2. Yes, water can stay liquid below zero degrees Celsius. ... When we apply pressure to a liquid, we force the molecules to get closer together. They can therefore form stable bonds and become a solid even if they have a higher temperature than the freezing point at standard pressure.

Hope it helps...
