What subatomic particle is responsible for combining the atoms together to form a new substance?
Tanya [424]
The answer to this question would be: electron

When atoms bind together, that mean they shared at least one electron. The electron is located on the outer side of the atoms so the electron from an atom can collide with other electrons from another atom. The protons and neutron can't make bind because it was in the middle of the atom and won't collide each other.
