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.
There are several elements that have more than 50 and less than 75 protons. 25 to be exact. The elements Tin through Rhenium on the periodic table meet your standards.
Iodine This element has more than 50 but less than 75 protons and it is in group17?
Iodine, I, has 53 protons and is in group 17.
Iodine (I) ... it has an At No of 53 & At Wt of 126.91 and is in VIIA
Iodine
IODINE
Iodine
Sulfur. definitely Sulfur
No
In amy line accrues the periodic table each step to the right indicates that the element contains one more proton than the element to its left. Nickel has one more proton (28) than cobalt (27) and occupies its proper position.
element
The atomic number defines an atom's identity, i.e. element. A group of atoms contatining the same number of protons in their nuclei belong to the same element even if they can have different numbers of neutrons or electrons associated with them. If two atoms have the same number of protons but different number of neutrons, they are called isotopes. If an atom has less or more electrons than its number of protons, it is known as an ion. In certain instances during radioactive decay, the number of protons in an atom's nucleus can actually change. This results in a transmutation (change of one element to another).
This chemical element is calcium (Ca).
All isotopes of an element have the same number of protons, otherwise they would not be the same element. What varies is the number of neutrons, they can be more or less than in the stable isotope(s) of the element.
Sulfur. definitely Sulfur
The expected answer is element 115, Ununpentium, if that has been discovered. Among stable elements, the answer would be bismuth.
Sulfur (S)
Sodium is more reactive then Magnesium as it is a group 1 element and magnesium is a group 2 element
No
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.

Atomic number is the number of protons. Atomic mass is (mostly) the sum of the masses of the protons and neutrons (more or less).
They will have more electrons, protons, neutrons, atomic mass etc.
An element with seventeen protons 9and no charge) would have seventeen electrons as well. If the element were an ion, it would have more or less electrons, depending on its charge.
