What was Bohr's Aomic Theory?
Bohr's Atomic Theory stated that all atoms revolve around the nucleus
What are the atomic number and atomic mass of the isotope Br 79?
The atomic number of any bromine atom is 35, and the atomic mass number is the number stated after the element name in the question, in this instance 79.
What is the name of the particles orbiting around the central part?
Assuming you are talking about an atom, which you really should have stated in your question, the nucleus (the "central part" of the atom) consists of neutrons and protons. The particles orbiting the nucleus are electrons.
What were the shortcomings of Bohr's model of the atom?
Rutherford stated that electrons orbits the nucleus. Thus if the electrons were orbiting the nucleus then they must be accelerating due to the centripetal force acting on it. This proved to be a flaw, due to Maxwell theory that electrons accelerating produces EMR which in turns would mean the electrons would loose energy and crash into the nucleus leading to a unstable atom. Which is not the case.
What is an electron neutron and protron?
Atom's were the smallest thing that we knew of in our universe, until one day a long time ago we split the atom and begun to take a look inside.In the center of an atom are proton's and neutron's. The center is also called the nucleus.Moving around the center of the atom are electrons. Electron's are now the new 'Smallest' thing known to man.Electrons have a negative chargeProtons have a positive charge andNeutron's have a neutral or no charge (some atoms may not apply to this rule)From the information of how many Electrons/Protons and Neutron's you can discover certain qualities and the family/place in the periodic table of elements.I've added links to help you further in understanding Atoms.In an atom a proton is a positive charge, an electron is a negative charge and a nuetron is a neutral charge.Protons are attracted to electrons, due to opposite charges.Electromagnetic force pulls them (Protons and Electrons) together.Protons and neutrons are found in the nucleus (center of the atom).

What does Mendeleev's periodic law stated?
physical and chemical properties are the fundamental property of d Atomic Mass.This law was stated in d year 1869.

Why does ionization energy decrease down the family?
You question is not very clearly stated but I think I know what you are asking. As you go down the column of any family of elements in the periodic table, you move to increasingly heavier and larger atoms. Their outer electrons are therefore farther from the nucleus, and even though the nucleus is larger and has a larger positive charge, the increased distance is the predominant influence, making the outermost electrons less tightly bound, and therefore more easily ionized, with a lower ionization energy.
What scientist proposed that electrons move around the nucleus in fixed paths?
niels bohr

Is the atomic number is equal to the nuclear charge?
the atomic number does not equal the number of atoms. the number of atoms is stated in the equation like: H2+O=H2O2 hydrogen atoms 1 oxygen atom the number says all.The atomic number tells the number of protons.
When was it stated that most of an atom's mass is in the nucleus?
1898
How does ionization energy down a group relate to trend in atomic radius as atomic number increases down a group?
ionization energies (IE) have to do with things called ions. Ions are atoms which have gained or lost electrons. The ionization energy is the amount of energy it takes to detach one electron from a neutral atom. Some elements actually have several ionization energies. When this is the case, we refer to them as the "first ionization energy" or 'I', "second ionization energy" or 'I2', and so on. Notice that the energy variable follows Ii where i is the orbital from which the electron is lost. Ionization is endothermic meaning that the atom or molecule increases its internal energy (takes energy from an outside source).
Is the mass of an atom uniformly distributed within the nucleus?
My God. NO! Protons and neutrons are in the central portion, called the nucleus, and electrons are in the outer part, forming shells around the nucleus. There is empty space between the nucleus and the electron shells.
