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.

∙ 13y agoif you know the definition of an element you could easily determine what it is:
" an element is a substance containing only one type of atom and no others "
so any compound that contains the same type of atom is called an element.
example: O2, H2, N2, Cl2....etc.

What object could describe determined'?
Any person can be described as "determined".
What is the color that an object appears to be determined by?
It is determined by the wavelengths of light that reach your eyes.
An element with the same number of protons and electrons as another atom of the element but with a different number of neutrons?
For the most part, yes the quantities of each are different. Light nucleii can have the same number of protons and neutrons and be stable enough to stay the same element (deuterium = 2H, 4He, 6Li , 10B, 12C, 14N, 16O, 20Ne, 24Mg, 28Si, 32S, 36Ar, 40Ca are stable), but a nucleus of a given element can sometimes have more or less neutrons, and be stable. Tin is the heaviest nucleus that has an isotope where #p = #n, and this isotope is very unstable
The what of an electromagnet is determined by the direction of current flow?
The electromagnet (polarity) is determined by the direction of current.
Is The pitch of a sound is determined by its wavelength and speed together or its?
The pitch of a sound can be determined by its frequencyalone.
Why is the period of an element determined by an electron configuration?
The period of an element is determined by electronic configuration.Period is same as the number of energy levels of the element.
What is an element is determined by the number of?
The identity of an element is determined by the number of protons in the nuclei of its atoms. This is the atomic number of an element.
The atomic number of an element is determined by the number of?
The atomic number of an element is determined by the number of protons within it's nucleus.
The atomic weight of an element is determined by what?
The atomic number of an element is determined by the number of protons in its nucleus.
Is an element's reactivity determined by the number of protons found in an atom of an element?
^.^
What is the identity of an element determine by?
The identity of an element is determined by the number of protons.
Is the atomic number of an element determined by its number?
Protons. This determines what material the element is.
How is the identity of the element determined?
the number of its protons
What can the period of a element be determined by?
electron configuration
What is determined of an element experimentally by X-ray diffraction of a crystal of the element?
Elemental carbon can have two different solid phases with differing spatial (position) ... Crystal structures are determined experimentally by X-Ray Diffraction. So the position of the element is determined experimentally by X-ray diffraction of a crystal of the element.
What is determined by the protons in nucleus of an element?
The number of protons in the nucleus determines the identity of the element.
How is the mass of 1 mole of an element determined?
It is the same as the element’s atomic mass, but in grams.
