Why sharing electrons causes atoms to bond together?
When electrons are shared between atoms, the nuclei of both atoms experience attraction towards the electrons and vice versa. At a certain distance, the attraction is maximal because the repulsion between the nuclei is small while the attraction of each nuclei to the electrons is strong. Thus, the atoms are held together by their attraction to the shared electrons.
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.
What is the force of attraction between the nuclei of atoms and the shared electrons?
Covalent bond
What force holds electrons and protons in the atom?
Electro-static attraction between a positively charged nucleus and negatively charged electrons.
What causes chemical bonds to form between atoms?
transferring or sharing electrons
Is an attraction between atoms so electrons are shared a physical bond?
is an attraction between atoms so electrons are shared in a physical bond
Why sharing electrons causes atoms to bond together?
When electrons are shared between atoms, the nuclei of both atoms experience attraction towards the electrons and vice versa. At a certain distance, the attraction is maximal because the repulsion between the nuclei is small while the attraction of each nuclei to the electrons is strong. Thus, the atoms are held together by their attraction to the shared electrons.
What are core electronics?
Inner core electrons are electrons that shield attraction between protons and valence electrons.
What is the strength of attraction between a nucleus and the outermost electrons?
1
The effect of inner electrons on the attraction between the nucleus and the outer electrons of an atom is called?
electronegativity

Why are valence electrons easier to remove from an atom than core electrons?
the force of attraction between then nucleus and the valence electrons is less than that between the nucleus and the core electrons
What is matalic bond?
an attraction between a + metal ion and the electrons surrounding it.
What is the process by which the core electrons partially block the attraction between the nucleus and the valence electrons?
chemical deviation
What is the force of attraction between a positively charged metal ion and the electrons in a metal?
electrostatic force
What is it called when electrons in the inner energy levels block the attraction between the nucleus and the valence electrons?
nuclear shielding
What is the force of attraction between the nulcei of atoms and shared electrons?
Covalent bond
