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.
a bohr model is shown by taking the number of valence electrons in an atom and put it in a circle around the atomic symbol of an atom
Simplest method - apply a voltage to a conductor.
Bohr's model of the atom, proposed by Niels Bohr in 1913, described the atom as having electrons orbiting the nucleus in specific energy levels or shells. It introduced the concept of quantized energy levels and laid the foundation for understanding atomic structure.
It is not always easy to tell whether an atom will lose or gain an electron in a reaction. However, this is a general rule that applies in many cases. Simply put, the atom with the higher electronegativity will gain an electron and the atom will a lower electronegativity will lose an electron.
Thomson said that charges are distriduted evenly in entitre atom. but Rutherford said that charges(electrons) are continuously revolving around the nucleus,a small region where the entire mass of atom is subjected to be. Thomson failed to put forward the concept of nucleus and orbitals.

The seven electrons in a nitrogen atom are distributed in energy levels called shells. The first two electrons fill the innermost shell, while the remaining five electrons are distributed in the second shell. Specifically, two electrons occupy the 2s orbital, and the other three electrons occupy the 2p orbitals.

Displaced electrons. Basically, when there is no electrical energy, you have electrons in orbitals around the nucleus of an atom, but when sufficient energy is put into the atom, the electron is lifted into an orbital higher than it normally is, and in certain metals, it can actually leave the specific atom when it does this and travel across others, producing an electric current.
This is called an electron. It is a tiny subparticle floating around the nucleus in what are knwon as orbitals. There are 2 electrons MAX per orbital, although electrons erpel each other, so if there is enough space to put one electron in every orbital and have them spread out, then the electrons prefer it that way.
An atom has the same amount of protons as electrons
Atoms of argon have a full outer (valence) shell, and this is why argon is inert. The electrons of an atom have different energy levels. It's conventional to call each collection of possible states of electrons for a given energy level a shell. Shells have finite capacity and argon has a full outer shell. Chemical reactions tend to rely on electrons jumping from one atom to another or two sharing the orbit of 2 electrons (a type of shell around 2 electrons if you like). If the shells are full it is usually more energy efficient for an electron to stay put rather than jump to another atom. consequently argon with its full shells rarely bonds.
The positivity and negativity of an ion is determined by the number of electrons compared to that of protons. If there are more electrons than protons in the ion, it is considered negative. It becomes negative by gaining electrons, which can happen a number of ways. Simply put, most often it gains electrons by pulling them off of other elements and molecules. The more electronegative an element is, the easier it is for it to do this. Elements are most stable in their "octet" configuration where all of the available spots in an orbital are filled. Elements with less than a perfect octet will rip electrons off of other things.
The Bohr atom model of Potassium describes the arrangement of electrons in a potassium atom with 19 electrons. According to the model, electrons occupy specific energy levels or orbits around the nucleus, with the outermost level containing 8 electrons in the case of potassium.
