Question

all atoms of an element have the same what

Answer 1

All atoms of the same element have the same number of protons. Atoms also may contain neutrons and electrons. Protons in atoms are positively charged. Electrons are negatively charged, while neutrons have no charge. Protons help the nucleus form in an atom and are made up of two up quarks and one down quark. The quarks can also be known as fermions and baryons. To determine the atomic number of an atom, one should count the number of protons within the nucleus.
