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.
if 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.
An element is determined by the number of protons in its nucleus, which is called its atomic number. This unique number of protons defines the element and determines its chemical properties.
The atomic number. this is the number of Protons in the nuclei.
Number of protons. This also gives an element its atomic number. (eg. hydrogen is element number 1; so has 1 proton, oxygen is 8, so has 8 protons; carbon is 6, so has 6 protons, etc)
An element is determined by the number of protons in the nuclei of its atoms. This is the atomic number of the element.

What determines an elements chemical properties?
An element's chemical properties are determined primarily by its electron configuration, which influences how it will react with other elements to form compounds. The number of protons in the atom's nucleus also plays a role in determining its chemical properties. Additionally, factors such as atomic size, electronegativity, and valence electrons contribute to how an element will interact chemically with other elements.
What is the hardness of berkelium?
The hardness of berkelium, a synthetic element, has not been specifically measured. However, as a general trend for actinide elements, berkelium is expected to be relatively soft, like most metals in the actinide series.
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
What did British scientist Henry Moseley determine?
British scientist Henry Moseley determined the concept of atomic number as the basis for the modern periodic table, demonstrating that it is a more fundamental property of an element than its atomic mass. He also used X-ray spectroscopy to accurately determine the atomic numbers of elements, which led to a more organized and predictive arrangement of the elements in the periodic table.
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.
Who determined the number of protons in each element?
The number of protons in each element is determined by the atomic number of the element. The atomic number corresponds to the number of protons in the nucleus of an atom. This number is unique to each element and is determined by the arrangement of electrons and protons in the atom.
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
The atomic weight of an element is determined by what?
The atomic weight of an element is determined by the weighted average of the masses of its isotopes, taking into account their abundance in nature. This value is typically found on the periodic table as the average atomic mass 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.
What is the place of an element in the modern periodic table determined by?
The number of protons in an atom of the element.
The identity of an element is determined by the number of protons?
Yes.
How is molar mass of an element determined?
the Atomic Mass in g/ml is the molar mass of the element
