The element with 72 electrons is Hafnium (Hf). Hafnium has an atomic weight of 72 and is a period 6, group 4 transition metal. It is the first element after the Lanthanides. Hafnium has 72 electrons in 6 shells with 2 electrons in the outer shell.
There is no such element as tantanium. I have seen the element tantalum sometimes referred to as tantanium, but this is incorrect. The element tantalum has 73 protons. Another possibility is that you are referring to the element titanium, which has 22 protons.
Tungsten has 74 protons and 74 electrons, but it has 110 neutrons. Tantalum has 108 neutrons, but 73 protons and 73 neutrons.
I'm assuming the symbol actually looks like this: 181Ta5+ If that's the case, it means that the mass number is 181, the element is tantalum, and the charge is +5. The atomic number of Ta is 73 (determined from the periodic table, see: http://www.webelements.com), so that tells it has 73 protons. The mass number if the # of neutrons + # of protons, so it has 181 - 73 = 108 neutrons. If it has a +5 charge, it must have 5 electrons less than the number of protons, so 73 - 5 = 68 electrons.
Tantalum has 73 protons, 73 electrons, and isotopes of Tantalum include a varying number of neutrons. The most common isotope, Tantalum-181, has 108 neutrons.
Radon (Rn) has the most protons of any element in Group 0 (18) with 86 protons. However, if or when Ununoctium is officially confirmed, that will become the element with most protons in that family, with 118 protons.

I dont think there is one.
Tungsten has 74 protons and 74 electrons, but it has 110 neutrons. Tantalum has 108 neutrons, but 73 protons and 73 neutrons.
Tantalum, with the chemical symbol Ta, is the chemical element with the atomic number 73.
Tantalum has 73 protons.
Protons are protons, no matter what element they are in.

what element contains 16 protons? what element contains 10 protons?
Each chemical element has a specific number of protons; the number of protons is equal to atomic number of the element.
Tantalum has 73 protons, 73 electrons, and isotopes of Tantalum include a varying number of neutrons. The most common isotope, Tantalum-181, has 108 neutrons.
The chemical element with 33 protons is: arsenic (As).
All atoms of the same element have the same number of protons. Atoms of different elements have different numbers of protons. The number of protons determines the element.
