Protons and neutrons are not included in Lewis electron dot diagrams because these diagrams focus specifically on the valence electrons of an atom, which are crucial for understanding chemical bonding and reactivity. Protons, being positively charged, contribute to the atomic number and identity of the element, while neutrons are neutral and contribute to the Atomic Mass. The Lewis structure emphasizes the arrangement and sharing of electrons between atoms rather than the nucleus or the overall atomic structure.
when compared to the mass of protons and neutrons, the mass of the electrons is negligible and hence not included in atomic mass.
How is this a question.
Mass number is defined as the number of protons and neutrons. It is related to Atomic Mass which incudes electron mass and nuclear binding energy , (binding energy reduces the overall mass relative to the combined masses of the protons and neutrons.) Electron mass is not included as mass number is element specific wheras the count of electrons varies depending on the chemical state. The mass of electrons is negligible compared to the mass of the protons and neutrons, binding energy is a larger effect.
the protons are positively charged that's how you know if it is a proton or an electron because a electron has a negative charge
8 protons 8 elentrons 8 neutrons in 8O16
The number of protons and neutrons is not changed; sodium lose one electron and chlorine gain an electron.
Oxygen is a p block element. It has 8 protons and neutrons.
Neither (protons are positive and neutrons are neutral).an electron has a negative charge

The nucleus is made up of protons and neutrons; the electrons form electron shells around the nucleus.

electron - electron cloud protons and neutron- nucleus
An electron cloud is made up of protons and neutrons.
The protons and neutrons are located in the atomic nucleus; the electrons are around the nucleus, arranged in shells,
1 proton, 0 neutrons, 1 electron
