less, decreases
all electrons are alike
Protons are contained within the nucleus, electrons surround the nucleus at a considerable distance (atomically speaking)
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.
Protons and neutrons are located within the nucleus. Electrons are revolving around the nucleus.
Because if the radius is big, then the large distance affects the strenght of the electron with the nucleus. This also increases reactivity in non metals since it will be easier to take away the electron :)
No, electrons are around nucleus but at a great distance.

valence electrons
shell
Protons and neutrons make up the nucleus in an atom, the electrons are in shells or orbits around that nucleus at quite a distance (relatively to the nucleus diameter)

A: If a nucleus is a point like a flag pole then the electrons are orbiting this nucleus at a very big distance like football filed distance and they have a charge too
Neils Bohr, in 1913.
Dalton proposed planetary model. He kept electrons at a distance.
