Why atom is chargeless?

Particles is found in the nucleus of an atom?
What atom has no charge in the nucleus?
Every type of atom has at least one proton in its nucleus. Protons are positively charged, and that means all atoms have a positively charged nucleus. There are no atoms that have no charge in the nucleus. If the question is intended to discover what part of the nucleus has no charge, it is the neutron that is the chargeless constituent of atomic nuclei.

Describe the presence of sub shells in a shell?
How do you know the number of electrons in the periodic table?
If it is the normal atom (not an ion) it will have the same number of protons and electons which will give it neither a positive nor negative charge. To the left of the elemental symbol you have two numbers, the top number (which will be a larger value) is the mass of the atom, this is the sum of the protons and neutrons as electrons are deemed of negligible mass (1/2000). The bottom number is the number of protons, as the atom is chargeless and proton = +1 charge; electron = -1 charge) this number will also be the number of electrons.
How is the structure of an atom or uranium-235 dfferent to the structure of an atom of uranium-238?
An isotope means an atom with the same amount of electrons and protons, but with different amount of neutrons. Relative weight of a neutron is 1, a proton is 1, and an electron is very small. So weight of an atom is approx. m neutrons + m protons. So, an uranium-235, as U is the 92th atom in periodic table, contains 92 protons, 92 electrons to be chargeless, and 143 (=235-92) neutrons. An uranium-238, from the definition of isotope, contains 92 protons, 92 electrons, and 146 (=238-92) neutrons. The difference is the 3 neutrons.
