There are two main variables that determine the distance of electrons from the nucleus. This is how many electrons are present, with less being farther away in the same energy level. The second is the energy level they are located in, with distance increasing with level.

What is the strength of attraction between a nucleus and the outermost electrons?

The strength of attraction between a nucleus and the outermost electrons is determined by the electric charge of the nucleus (protons) and the distance between the nucleus and the electrons. This attraction is the basis for the force that holds atoms together and is essential for the stability of matter.


Are electrons next to the nucleus?

No, electrons are around nucleus but at a great distance.


Why do force of attraction between nucleus and electrons decrease in alkali metal as increase in size?

As alkali metals increase in size, the distance of the outermost electrons from the nucleus increases. The attraction between the electrons and the nucleus is electrostatic, and it is a fundamental property of electrostatic attractions that the attraction decreases with increasing distance between the attracting charges. Another way of describing this is that the attractive force is partially "screened" by the inner electrons between the outermost electrons and the nucleus.


What is the approximate distance between an electron and the nucleus?

The Bohr radius, is the estimated distance between protons in the nucleus and electrons - but electrons aren't solid, stationary particles... The simple answer would be about one-twentieth of a nanometre. But this would only be reasonable if the electron were a solid particle.


An increased distance of the electrons from the nucleus causes th be affected?

When electrons are farther from the nucleus, the electrostatic force of attraction between the protons in the nucleus and the electrons decreases, leading to weaker binding of electrons to the nucleus. This can result in higher energy levels for the electrons, potentially affecting the reactivity and chemical properties of an atom.


What is the Attraction of nucleus for electrons is reduced by?

Distance.


Why are electrons usually found near the nucleus?

Electrons are usually found near the nucleus due to the attractive force of the positively charged protons in the nucleus. This force keeps the electrons in orbit around the nucleus rather than floating away. The balance between the attractive force of the protons and the repulsive force of the electrons determines the electron's energy level and distance from the nucleus.


What pulls the electrons towards the nucleus?

The attraction between the positively charged nucleus and the negatively charged electrons creates an electrostatic force that pulls the electrons towards the nucleus. This force is governed by Coulomb's law, which states that the force between two charges is directly proportional to the magnitude of the charges and inversely proportional to the square of the distance between them.


Are all the electrons always the same distance from the nucleus?

all electrons are alike


Why does the atomic radius change as electrons are added to a shell?

The atomic radius decreases as electrons are added to a shell because the increasing number of electrons increases the electrostatic force of attraction between the electrons and the nucleus, pulling the electrons closer to the nucleus and reducing the atomic radius.


Why don't electrons crash into the nucleus?

Electrons do not crash into the nucleus because they are constantly in motion and are held in orbit around the nucleus by the electromagnetic force. This force keeps the electrons at a certain distance from the nucleus, preventing them from colliding with it.


What is found between the electrons and the nucleus in an atom?

The space between the electrons and the nucleus in an atom is filled with empty space and the nucleus contains protons and neutrons.
