This is called also protium and contain 1 proton and 1 electron.
Mass of hydrogen atom = 1 amu Mass of ununoctium atom = 294 amu So ratio = 1 : 294
Yes but only if there are no neutrons, such as in hydrogen (atomic number=1, relative Atomic Mass-1)
As Deuterium and Tritium are both merely isotopes of Hydrogen and not elements in their own right, they both have an atomic number of 1, just like Hydrogen (Hydrogen-1). Deuterium (Hydrogen-2) has an atomic mass of 2, and Tritium (Hydrogen-3) has an atomic mass of 3.
Deuteriums emision spectrum either is like hydrogen http://chemed.chem.purdue.edu/genchem/topicreview/bp/ch6/bohr.html or like http://en.wikipedia.org/wiki/Image:Deuterium_lamp_1.png
Protons and electrons both have mass. Therefore a hydrogen atom that contains one or both will have mass. (It will, however, be less massive than a hydrogen atom that also has neutrons.)
Only if the atom is hydrogen-1! The mass number of the atom is equal to the sum of the numbers of protons, which is the same as the atomic number, plus the number of neutrons. The only non-radioactive atom without neutrons is hydrogen-1.
all atoms have different masses Mass of an atom is due to protons and neutrons present in an atom and number of proton is something that distinguish between atoms, therefore mass of hydrogen is different to the mass number of oxygen, hydrogen's mass is 1 as it has only 1 proton and no neutrons, and oxygen mass's is 16 as it has 8 protons and 8 neutrons.

H has a mass number of 1 (one proton, no neutrons), Carbon has a mass number of 12 (6 neutrons, 6 protons) and O has a mass number of 16 (8 neutrons and 8 protons).
The 'standard' hydrogen atom has atomic number 1, atomic mass 1, no neutrons. Although there are 2 other isotopes of hydrogen: - (cant confirm name) which has atomic mass 2 and 1 neutron. - (cant confirm name) has atomic mass of 3 and 1 neutron. All isotopes have atomic number 1.

They are not. Atomic number is the total number of protons in an atom. Mass number is the total number of protons and neutrons. The only isitope in which they are the same is Hydrogen-1 with 1 proton and no neutrons.
