What is the attraction between the nucleus and electrons?

The attractive force of the nucleus on its electrons is known as the effective nuclear charge ( Zeff ), and decreases as you get further from the nucleus. The nucleus is positive and the electrons are negative, which obviously means they attract.

What is the attraction between the nucleus and electrons called?

Chemical bond refers to the forces holding atoms together to form molecules and solids. This force is of an electric nature, and the attraction between electrons of one atom to the nucleus of another atom contributes to what is known as chemical bonds.

What is the attraction between the nucleus and valence electrons?

The size of an atom is determined by the electrostatic attraction between the positive nucleus and the valence electrons. The force of this attraction is proportional to the size of charge and inversely proportional to the distance between the charges.

What is the attraction between protons and electrons called?

Electromagnetic Force of Attraction: exists between negative electrons and positive protons in the nucleus and keeps electrons in the area surrounding the nucleus. Electromagnetic Force of Repulsion: exists between positive protons in the nucleus is overcome by the strong nuclear force between protons and neutrons.

What is a electrostatic attraction?

Electrostatic attraction. between oppositely charged species (positive and negative) results in a force that causes them to move toward each other, like the attraction between opposite poles of two magnets. In contrast, electrostatic repulsion.

How and why does the attractive force between the valence electrons and the nucleus change as you move down a group?

As you go down a group, the nuclear charge decreases because the valence electrons move further away from the nucleus depleating the force of attraction between the nucleus and the electrons. … The amount of energy needed to remove an electron from an atom. Energy must be spent in order to overcome the attraction.

How does this change the attraction between the nucleus with the positively attracted protons and the valence electrons?

Moving across period, protons are added to the nucleus increasing the effective nuclear charge. This causes a stronger force of attraction between the valence electrons and the nucleus.

How and why does the force of attraction between the nucleus and the valence electrons change as you move across a period?

The net force of attraction between the nucleus and the valence electron in an atom increase as you move across a period from left to right. As you move across a period, the valence electrons in the atom experience a stronger pull toward the nucleus. DECREASES.
