How does the size of an atom affect the attraction connection between electrons and the nucleus?

Since the force of attraction between nuclei and electrons increases, the size of the atoms decreases. The effect lessens as one moves further to the right in a period because of electron-electron repulsions that would otherwise cause the atom’s size to increase.

What is the force of attraction between electrons and the nucleus?

The attractive force between the electrons and the nucleus is called the electric force.

What could be changed to increase the attractive force between the nucleus and electrons?

As more protons are added, the attractive force on the electron increases.

How does the size of an atom affect its ability to attract additional electrons?

As atomic radius increases, valence electrons are more easily removed or the force of attraction between the nucleus and the valence electrons decreases going down a group.

Which of the following affects the size of an electric force?

The first factor is the amount of charge on each object. The greater the charge, the greater the electric force. The second factor is the distance between the charges. The closer together the charges are, the greater the electric force is.

What force causes attraction in the nucleus?

The strong nuclear force pulls together protons and neutrons in the nucleus. At very small distances only, such as those inside the nucleus, this strong force overcomes the electromagnetic force, and prevents the electrical repulsion of protons from blowing the nucleus apart.

How does the effect of the electromagnetic force in the nucleus compare with its effect on the atom as a whole?

As more protons are added to the nucleus, the electromagnetic force of repulsion between them gets stronger, while the strong nuclear force of attraction between them gets weaker. This puts an upper limit on the number of protons an atom can have and remain stable.

What happened about the electron infinity when the force of attraction between nucleus and electron decreases?

The less valence electrons an atom has, the least likely it will gain electrons. Electron affinity decreases down the groups and from right to left across the periods on the periodic table because the electrons are placed in a higher energy level far from the nucleus, thus a decrease from its pull.

How will the size of an atom affect its ability to attract additional electrons?

Electronegativity is a property that describes the tendency of an atom to attract electrons (or electron density) toward itself. An atom’s electronegativity is affected by both its atomic number and the size of the atom. The higher its electronegativity, the more an element attracts electrons.
