What is the strength of attraction between a nucleus and the outermost electrons?
1
Why are electrons attracted to the nucleus?
Put simply, a nucleus is made up of protons and neutrons, protons have a positive charge, this attracts the negative charge of the electron.
Regions where electrons are located?
Electrons are bound inside an electrostatic potential well around the nucleus; ext. energy is needed for the electron to escape.
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
Which phrase best describes a metallic bond?
A metallic bond is one where delocalized valence electrons of the metal are attracted to any of the metal cations. The electrons are delocalized meaning they do not stay with any particular nucleus. The bonds are held together by electrostatic interaction between the delocalized electrons and the positive cations.
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.
How are electrons held within a atom?
electrostatic force between the nucleus and the electrons.
What is the strength of attraction between a nucleus and the outermost electrons?
1
What keeps electrons in the space around a nucleus?
The electrostatic forces between the protons and the electrons keep it in orbit.
Does the chlorine have electrons in its nucleus as in its outermost shell?
No. Electrons are located in the electron cloud surrounding the nucleus.
How does electrostatic interaction between the outermost electron and nucleus vary across the periodic table?
Across teh period, the atomic number increases and subsequently the number of protons in the nucleus increases. hence the extent of electrostatic attraction also varies.
What makes the particles of atom orbit?
The force that keeps them in orbit is the electrostatic attraction between the atom's nucleus and the electrons.
What must happen for a nucleus to be stable?
The strong nuclear force must balance electrostatic forces in the nucleus
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.
The chemical behavior of an atom depends upon?
The outermost electrons, meaning the ones in the valence shell of the atom.
What are the electron farthest from the nucleus called?
Electrons farthest from nucleus are valence electrons. They are present in outermost orbit.
If electrons have the most energy in an atom electrons in an electron cloud electrons in the outermost electron shell electrons in the innermost electron shell electrons in the nucleus?
Electrons in the outermost energy shell (valence shell) have the most energy.
