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!
Which electrons are involved in bonding'?
At times the electrons involved in bonding are shared equally between the nuclei of two atoms and the bond is called a pure covalent bond. More often, however, the sharing is unequal and the electrons spend more time around the nucleus
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.
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 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 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.
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 coulomb force is the dominant force between the electrons of an atom and the nucleus. It is the standard force of attraction between positive and negative charges. (Of course, the electrons also interact with each other also through the repulsive coulomb force expected of like charges.) The forces between the nucleus and the electrons is the same basic coulomb force fo all electrons, inner electrons or outer electrons or any electrons. (Of course, the type of force is the same but the strength of the force varies with distance being weaker for more distant electrons.) Essentially all of chemistry is determined by this simple inverse square force of attraction and repulsion. Other forces such as the force of gravity or the more exotic nuclear forces and electroweak interactions are so small as to be irrelevant except in special circumstances.)
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 thermion?
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.
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.
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, the are on the outermost layer of the atom
