Answer: Option B) Atom
Explanation:
An atom is the simplest particle of an element that can retain all the chemical properties of the element, and therefore take part in a chemical reaction.
Thus, an atom of zinc (Zn) represent fully the entire properties of elemental Zinc. For instance: an atom of zinc has a mass of 65.38g.
A pure substance is a element made up of only one type of atom or molecule.
I think the answer is either C or D. Hope this helps!
answer this is so hard its impossible butt I'll ask my dad
2H consists of one proton and one neutron. The atomic mass of a proton is 1.00782u. The atomic mass of a neutron is equal to 1.00866u
Total mass=2.016u and mass of deuterium is equal to 2.01u
Mass difference= 0.002388u
BE = 0.002388×(3×108)²
=3.56912×10-13J
=2.230 Mev
=1.1153 Mev/nucleon
