How are electrons held within a atom?
electrostatic force between the nucleus and the electrons.
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
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 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.)
What energy relations exists within the atom as electrons revolve about the positive nucleus?
there is a force of attraction between the positive nucleus and each negative electrons, and this force is counterbalanced by one that is determined by the orbital motion of the electron.
What kind of a force exists between a nucleus and outer level electrons attractive or repulsive?
attractive
What force holds electrons and protons in the atom?
Electro-static attraction between a positively charged nucleus and negatively charged electrons.
What kind of basic force pulls electrons close to the atomic nucleus?
The electric force pulls electrons close to the atomic nucleus. The protons in the nucleus have a positive charge, and so attract the negatively charged electrons.
What are the advantages of Rutherford's atomic model?
The electrostatic force of attraction between electrons and nucleus was likened to the gravitational force of attraction between the revolving planets and the Sun.
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.
What is the part of atom?
An atom is composed by a nucleus where protons and, in case, neutrons are joined by the so called strong force, and a number of electrons equal to the number of protons in the nucleus. Electrons are in equilibrium around the nucleus (in a stable state) due to electromagnetic attraction between their negative charges and the positively charged protons in the nucleus. In the nucleus, the strong force (that is the net result of inter-quarks forces that emerges out of protons and neutrons) is stronger with respect to electromagnetic repulsion between positively charged protons, so that the nucleus is in a stable state (protons do not repel each other) even if it is formed by all positive and neutral particles.
What force initiate the motion of electrons around the nucleus?
centrifugal force
