What element has 53 protons and 74 neutrons?
Tungsten has 74 protons and 74 electrons, but it has 110 neutrons. Tantalum has 108 neutrons, but 73 protons and 73 neutrons.
How many protons does Tantalum have?
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.
How many protons neutrons and electrons are in Tantalum?
Protons: 73 Neutrons: 108 Electrons: 73
How many protons neutrons and electrons for 181Ta 5?
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.
Protons element 25?
Manganese, the 25th element, has 25 protons.

What is the name of protons in the atoms of an element?
Protons are protons, no matter what element they are in.
How may protons does tantalum have?
Tantalum has 73 protons.
How many protons are in an atom of a pure element?
Each chemical element has a specific number of protons; the number of protons is equal to atomic number of the element.
What element contains 16 protons?
what element contains 16 protons? what element contains 10 protons?
Protons element 25?
Manganese, the 25th element, has 25 protons.

Do protons of an element vary?
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.
