an atom is just one thing. atoms are single molecules are plural
The rings around an atom can also be called an Electron Shell.
A calcium atom has 20 electrons arranged in four energy levels or rings around the nucleus.
A gold atom typically has a total of six electron shells (rings) surrounding its nucleus.
Electrons are placed on the rings (or energy levels) of an atom. The number of electrons in each ring is determined by the atom's atomic number and follows specific rules based on the electron configuration.
atomic mass means he weight of atom so electron is lighter than proton and neutron thats why it not count in mass of atom
Orbitals
It has most likely has 3 rings with electrons surrounding the nucleus which contains the protrons and the neutrons.
Lithium is in the second period. It is an alkali metal. It has 2 rings of electrons.
Cut it open and count the rings.
Cut it in half and count the rings.
cut it in half and count the rings
Cut it in half and count the rings.
