Uup, or ununpentium with 115 electrons
Sulfur. definitely Sulfur
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 number of protons an element has is given by its Atomic Number in the Periodic tableThe Atomic Number of Iron = 26The Atomic Number of Phosphorus = 15
Neon
Sulfur. definitely Sulfur
Carbon is the element in the same family as lead with atomic number less than sodium.
Sulfur (S)
If you look at a periodic table and go to group one, and than the element with an atomic number of 37 it is Rb. The atomic number is the number of protons and electrons. Rb is Rubidium.

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.

This chemical element is calcium (Ca).
there is no such element

It is an isotope of the element.
They will have more electrons, protons, neutrons, atomic mass etc.
