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.
Uup, or ununpentium with 115 electrons
Any one element can ONLY have a single fixed number of protons. Th only element with a number of protons that sits between 50 and 75 in group 17 of the periodic table is Iodine (I), with 53 protons.
Gold has the most protons per atom, because it has a higher atomic number than any of the other elements listed.
The atomic number of the element refers to the number of protons of an atom: all atoms of an element have this number of protons. A neutral atom of the element will have the same number of electrons.
51, just like all the other isotopes of Antimony. The amount of protons does not change in any of the isotopes of any element. If it were to it would be a different element.
The elements in group 15 are nitrogen, phosphorous, arsenic, antimony and bismuth. Bismuth has by far the most protons out of the group, with 83.
Uup, or ununpentium with 115 electrons
The expected answer is element 115, Ununpentium, if that has been discovered. Among stable elements, the answer would be bismuth.
Any element with 7 protons would be Nitrogen
Protons are components of the atomic nucleus of any chemical element.
calciumThe element sulfur's atomic number is 16, so there are 16 protons in its nucleus. The element bromine's atomic number is 35, and there are 35 protons it its nucleus. This means the element will have an atomic number between 16 and 35. Since the question asked which Group 2 element fits in that window, we can go to the periodic table and look down the column of Group 2 elements and find that calcium is the element so described. It has the atomic number 20, and that means 20 protons in its nucleus.Remember that the Groups on the periodic table of elements are the vertical columns, and they range from Group 1 to Group 18. Group 2 elements are the so-called Alkaine Earth metals. A link is provided to the Wikipedia post on the periodic table. Bookmark this one, kids! Each element on the table is a hyperlink to the Wikipedia post on that element. Even the Group numbers are hyperlinks to the post on that Group! It just doesn't get any better that that.
In an atom of any isotope of any element, there is a number of protons which is similar to the number of electrons.

None of them. That's way to many protons for any element. The highest number of protons in the periodic table is only 118.

No, there can be no other element that has the same number of protons as sulfur, and that is because elements are defined by the number of protons that they have. Therefore no two elements can have the same number of protons; if they did, they would be the same element.
