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.

Why electrostatic forces exist between nucleus and outermost electrons?
Electrostatic forces between the nucleus and outermost electrons exist due to the attraction between opposite charges. The nucleus carries a positive charge, while electrons carry a negative charge. This attraction keeps the electrons in orbit around the nucleus, creating stability within the atom.
What is the strength of attraction between particles in a solid?
In a solid, the strength of attraction between particles is strong compared to liquids and gases. This is because the particles are closely packed and have limited freedom to move, resulting in firm bonding forces between them.
What electrons are involved bonding?
Valence Electrons!
Is a force of attraction between any two objects?
Gravity is a force of attraction between any two objects with mass. The strength of the gravitational force is determined by the masses of the objects and the distance between them.
Which electrons are involved in bonding'?
Valence electrons are the electrons involved in bonding. These are the electrons in the outermost energy level of an atom and determine an atom's reactivity and ability to form bonds with other atoms.

What is the difference between a valence electron and a shielding electron?
Valence electrons are electrons on the outermost shell/orbitals. Sheilding electrons are inner electrons that block valence electrons from protons causing less attraction.
Why do force of attraction between nucleus and electrons decrease in alkali metal as increase in size?
As you move down an alkali metal group, the size of the atoms increases due to the addition of more electron shells. This increase in distance between the nucleus and outer electrons leads to a decrease in the force of attraction between them. The outer electrons are shielded from the nucleus by the inner electron shells, resulting in weaker attraction forces in larger alkali metal atoms.
Why does valence electron give up outermost energy easily?
The force of attraction between the atom's nucleus and its valence electrons are the least. Hence valence electrons are lost easily.
What electron forces exist between the nucleus and the outermost electrons?
The main electron forces between the nucleus and the outermost electrons are the electrostatic attraction between the positively charged nucleus and the negatively charged electrons, and the centrifugal force resulting from the electrons' motion around the nucleus. Additionally, electron-electron repulsion forces can come into play due to the repulsion between negatively charged electrons.
Why does bigger size atom have more shielding effect?
The bigger the atom, the larger the number of electrons between the outermost energy level and the positively charged nucleus. As a result, the attraction between the electrons in the outermost energy level and the nucleus are slightly weaker, and so, the larger the atom, the greater the sheilding effect.
What is the difference between electrons and thermions?
free electrons drift away from atom's outermost shell because of loose force of attraction. but thermions are forced out of atom by heat energy. free electrons are responsible for flow of electricity whereas thermions are responsible for thermionic emission.

Why do metals get more reactive the further down the group they are?
Metals get more reactive as you move down a group because the outermost electrons are further away from the nucleus, which decreases the attraction between the nucleus and electrons. This leads to easier loss of electrons, resulting in increased reactivity.
The mutual attraction or repulsion between electrons or protons is attributed?
The mutual attraction or repulsion between electrons or protons is attributed to the electromagnetic force. This force is responsible for interactions between charged particles and is mediated by virtual photons. The strength of this force is determined by the charges of the particles and their separation distance.
Which electrons are use to form bonds?
Valence electrons are the electrons that are used to form bonds between atoms. These are the electrons in the outermost shell of an atom.
What types of electrons are responsible for bonding between atoms?
Valence electrons are responsible for bonding between atoms. These are the electrons in the outermost energy level of an atom that are involved in forming chemical bonds with other atoms.
