electron - electron cloud protons and neutron- nucleus
Electrons are found outside the nucleus in the electron cloud.
The electrons are not in the nucleus, they are around the atom in a "probability cloud" due to heisenburgs uncertinty principle.
The electrons placed near the nucleus.
The main reason that electrons and protons are dominant in matter is that these are stable particles and do not decay spontaneously. The neutron, which is unstable outside of a nucleus, is stable within the nucleus of an atom. The reason that the protons and neutrons are bound together is the strong nuclear force. The coulombic attraction between protons and electrons then binds the electrons to the nucleus to form an atom.
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.

the force of attraction between then nucleus and the valence electrons is less than that between the nucleus and the core electrons

These are the chemical properties.
Between the electrons of one atom and the nucleus of another.
The attraction between the atomic nucleus and electrons is less strong.
Distance.
The attraction between electrons and the atomic nucleus is changed.
The electrostatic force of attraction between electrons and nucleus was likened to the gravitational force of attraction between the revolving planets and the Sun.
Electro-static attraction between a positively charged nucleus and negatively charged electrons.
