How are the number of protons in an element determined?
Well... the element number defines the number of protons, and usually the electrons. the neutrons are determined with... i dunno :P I.E. hydrogen is 1. Therefor, in hydrogen there are 1 protons and 1 electrons.
The number of protons in the nucleus determines the?
The element it is hydrogen has 1 proton, helium 2, by changing protons you change what element it is.
How many protons and neutrons does a nucleus of an atom contain?
Each element has a different number of protons and neutrons. So it changes for each element.
Could the number of protons in the nucleus of an atom be unique for each element?
Yes, the number of protons defines what element it is. 1 proton = Hydrogen, 2 protons = Helium and so on
What is the symbol of element that have 100 neutrons and 69 protons?
The element with 45 protons is Rhodium which has the chemical symbol Rh. Rhodium is a transition metal in Group 9, Period 5 of the Periodic Table. Rhodium has 45 electrons in 5 shells with 1 electron in the outer shell.
If scientists have determined that a neutral atom of rubidium has an atomic number of 37 and a mass number of 85 how many protons neutrons and electrons does the atom have?
Rubidium's atomic number is 37 and atomic number is the same as the protons (37 protons) Protons equal electrons so there is the same number of protons and electrons (37 electrons). The atomic mass of this element is About 85, and protons and neutrons weigh about 1 so you can subtract 37 from 85 to get and 48 neutrons. 37 protons, 37 electrons and 48 neutrons.
How many electrons does Rubidium have?
The atomic number of rubidium is 37. That means it has 37 protons and 37 electrons. After we fill in the first 37 orbitals with electrons, we get the configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s1. Since 5 is the highest numbered shell, rubidium has 1 valence electron.
Which group 2 element has fewer protons than bromine but more protons than sulfur?
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.

What is equal to the number of protons in an element?
The atomic number in an element is equal to the number of protons in an element. For example, Hydrogen has an atomic number of 1 and 1 proton.
How many electrons protons and neutrons does rubidium have?
Its atomic # is 37 so 37 protrons and electrons as for nuetrons it is 85(atomicmass)- 37(the atomic number)=48
Why does iodine have 53 electrons when it is in group 7?
It does not matter what group an element is in when determining the number of electrons; what matters is the number of protons. If an element has 53 protons, it will have 53 electrons to balance the number of protons. Each proton carries a positive charge of 1, each electron carries a negative charge of 1. In a neutral atom, the number of negative charges always equals the number of positive charges.
What does the atomic number tells you about the element?
It tells you (1) how many protons are in the element, and (2) what the element is since all atoms of an element will have the same number of protons.It's D. The number of protons in its atoms.It tells how many protons/electrons that element has.

How many protons does a standard hydrogen have?
A standard hydrogen atom has 1 proton. The Atomic Number of any element is the number of protons that element has.
The number of protons in the nucleus determines the?
The element it is hydrogen has 1 proton, helium 2, by changing protons you change what element it is.
