What is the difference between uncharged and non electrified

Although these two terms can be considered synonymous in many contexts, they may have different meanings in specific contexts.

Generally speaking, uncharged means that the positive and negative charges in the macroscopic object are completely canceled out, and the whole does not present a net charge. For microscopic particles, uncharged usually means completely uncharged, e.g. neutrons and neutrinos. Neutral atoms, on the other hand, can usually not be said to be "uncharged", but can only be said to be "uncharged" or "uncharged", or "not charged as a whole", and so on.

In some cases, neutral atoms cannot even be said to be "inelectrically impermeable", for example, when considering the interaction between two neutral atoms (when they are close together), they cannot be said to be "uncharged", or "incapacitated". Electrons and electrons, nuclei and nuclei, and electrons and nuclei in two neutral atoms are electromagnetically present at any time, and there is a significant electrical interaction between the two atoms, from which the chemical bonds and intermolecular forces are mainly due (although the neutral atom as a whole appears to be uncharged). This electrical effect is only significant when the distance between the atoms is around the diameter of the atom, and it is small or almost non-existent when it is a little distant (beyond two or three diameters).

Although there are a large number of electrons and protons inside macroscopic objects, the distance between the two objects is usually much larger than the diameter of the atom, so there is almost no electrical interaction between macroscopic objects without net charge.

When two macroscopic objects are in close contact, significant electromagnetic interaction can occur between their surface atoms. Macroscopic forces such as friction and elastic force are actually the overall manifestations of microscopic electromagnetic forces. Therefore, uncharged macroscopic objects are not electrocharged at all times.

If you have any questions, please feel free to ask.

Uncharged generally only macroscopic matter is not charged, and there is another type of uncharged microscopic particle: neutron; Electromagnetism generally refers to the relationship between microscopic particles, that is, positive and negative charges cancel each other out. Because as long as there is matter, there must be electricity, because the atom is one of the elementary particles that make up matter, and the atom must be composed of positively charged protons and negatively charged electrons.

Totally personal opinion, hehe.

Uncharged means that an object is not charged when it has an equal amount of positive and negative charges, and uncharged means that it does not have any positive or negative charge.

Non-energized means that the metal is not electrified, and the electrogenous metal is electrified.

The ones that can directly constitute pure substances are: molecules, atoms.

Charged particles are: ions, nuclei, and electrons.

Invisible particles are: molecules, atoms, neutrons.

In the same courier atom, the number is equal for: protons, electrons.

Protons and electrons are electrical, right? Protons are positively charged and electrons are negatively charged.

Atomic number = number of nuclear charges = number of protons = number of electrons outside the nucleus.

The nucleus is made up of protons and neutrons (except hydrogen, hydrogen has no neutrons), so the nucleus is positively charged, and the number of points in the nucleus depends on the number of protons.

In the second year of junior high school this year, chemistry has not been taught, and the above are self-taught in encyclopedias.
