Isotope - the same element, but different atomic mass so 1)35 Cl and 37 Cl
<span>Synthesis, decomposition, single replacement and double replacement.</span>
Protons and neutrons are in the nucleus of an atom, whereas electrons are present in orbitals, or shells, outside an atom. Electrons are negatively charged, protons positive, and neutrons have no charge, or are neutral. Protons and neutrons have a relative mass of approx. 1 Atomic Mass Unit (amu), whereas electrons have a relative mass of approx 0.00055 amu.
