To a certain extent yes. In a balanced element the number of electrons match the number of protons in the core of the element. If electrons have been added or removed (as in an ion) then you would need to know the exact number added/removed, or rebalance the element, in order to determine the specific element.
You can determine whether the atoms are the same element with out looking at the nuclei. This can be done by testing for specific properties.
They have the same number of protons. but different number of neutrons
Radioactivity
No. Binding energy differs from element to element,
By the number of protons in the nucleus. So the atomic number decides the element. If it is 1, then that is Hydrogen element. 2 is for Helium, 3-Lithium, 4-Berilium, 5-Boron and so on. Gold element has 79 protons in its nucleus. Mercury has 80. So with a high sophisticated technology if we take only one proton from each mercury atom, then we can produce gold. So mercury has been changed into gold. So transition of element is only by physical means not by chemical means.
produced when billions of nuclei from uranium, a radio active element, split apart in a nuclear fission reaction. :D By: Chelsea, a dumb blonde (:
Radioactive.
Silicon
An element's number of protons is the same as its atomic number.
Number of protons in the nuclei of their atoms.
Joining two nuclei to produce an atom of a different element is called fusion.
carbon
Neutrons in their nuclei.
Helium
mass and whether or not it's a metal. also how volatile it is
Atomic number is the number of protons in the atomic nuclei of the atoms of an element.
The atomic number of an element is the number of protons in the nuclei of its atoms, and is unique to each element.
Atomic nuclei have positive electrical charges. The size of the charge depends upon the element in question.
describe the relationship between two isotopes of an element and protons and neurtons in the elements nuclei .
