Me with this quickly
which statement is completely accurate?

1) atoms atoms of the same element always have different numbers of neutrons
2) atoms of the same element can have different numbers of neutrons
3) atoms of the same element can have neutrons but exist without protons
4) atoms of the same element always have different atomic weights

4( atoms of the same element always have different atomic weights)

Explanation:

the number of protons in the atoms of the same type can be different especially in isotopes

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
