When an atom is electrically neutral, it means that the overall charge of the atom is zero. The charge from a proton or electron are of equal strength, therefore if an atom has an equal number of protons and electrons, it will be electrically neutral.

Atoms is electrically neutral as the number of protons is equal to the number of electrons. Therefore the negative and positive charge cancels out.

Why is an atom electrically neutral? An atom is electrically neutral because the number of negatively charged electrons outside the nucleus equals the number of positively charged protons inside the nucleus. An atom in which this electron-proton balance is not maintained has a net charge.

When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral.

Heavier atoms tend to have more neutrons than protons, but the number of electrons in an atom is always equal to the number of protons. So an atom as a whole is electrically neutral.

Every element has the same number of electrons orbiting the central nucleus. The negative charge from the electrons cancels the positive charge from the protons, so when you consider the whole thing, these atoms are all electrically neutral.

Now it is possible to see a movie of an electron. Previously it has been impossible to photograph electrons since their extremely high velocities have produced blurry pictures. In order to capture these rapid events, extremely short flashes of light are necessary, but such flashes were not previously available.

The beams of electrons Thomson generated in his Crookes tube experiment proved particularly useful. Today similar beams are generated by electron microscopes, and the most powerful of these microscopes can actually create images of individual atoms.

An electron looks like a particle when it interacts with other objects in certain ways (such as in high-speed collisions). When an electron looks more like a particle it has no shape, according to the Standard Model. Therefore, in the sense of particle-like interactions, an electron has no shape.

The electron is the least-massive carrier of negative electrical charge known to physicists. This violates “charge conservation”, which is a principle that is part of the Standard Model of particle physics. As a result, the electron is considered a fundamental particle that will never decay.

Protons—whether inside atoms or drifting free in space—appear to be remarkably stable. We’ve never seen one decay. However, nothing essential in physics forbids a proton from decaying. In fact, a stable proton would be exceptional in the world of particle physics, and several theories demand that protons decay.

The law of conservation of energy, also known as the first law of thermodynamics, states that the energy of a closed system must remain constant—it can neither increase nor decrease without interference from outside.

Nothing we have observed if tge behaviour of electrons indicates that they are in any sense alive. Therefore they can not die. As far as we know, the electron is a fundamental point particle with no internal structure, so there is no way for the electron to fall apart in smaller pieces.

No. Stable atoms do not decay. The only problem is that it is very difficult to tell whether a particular isotope is stable or just extremely long at decaying. Bismuth-209 used to be thought of as stable.

Because bound electrons spread out into fuzzy density waves, there is no definite “edge” to an atom. The electron actually spreads out to fill all space, although far away from the atom it is thin enough to be negligible. Interestingly, electrons in the atom even spread out so as to overlap with the nucleus itself.

Do atoms reproduce? In the sense that living organisms reproduce, no, atoms do not reproduce. Some atoms are radioactive and decay into other atoms. Some emit “alpha” particles when they decay.
