the protons and the neutrons are in the nucleus

protons are positive

neutrons and neutral

the electrons move around the nucleus in orbitals are are negatively charged

ummmmmmmmm the electrons are really light and do not affect the weight of the atom and the nucleus is very massive as well as dense but extremly small, this was shown through rutherdfords gold foil experiment

Electrons orbit the atom, are negative and have a mass of 9.11×10-31kg.

Protons are located in the nucleus, are positive and have a mass of 1.67×10-27kg

Neutrons have no charge, are also located in the nucleus and are about the same size as protons.

atom has nucleuse +ve charge , this nucleuse is found in the centre of the atom it contains number of +ve protons and numbers of neutral neutrons , and around this nucleus there is electrons which are -vely charged and rotate around nucleuse…….know nothing about the mass , if i helped you plz inform me

ma email is [email protected]

ok —electron is in the electron cloud and it is negatively charged sorry dunno the mass

—-proton is positively charged (dunno mass or location sorry)

—-neutron is in the nucleus and is neutrally charged (no charge)

thats all i remember from 9 grade sorry hope this helps
