Isotopes of an element have the same number of protons and electrons, but different numbers of neutrons. Any element is made up of a combination of isotopes.
For example if you are looking at carbon, there is carbon-12 and carbon-13, which are stable, and carbon-14 which is radioactive. This is true for many elements, and the Atomic Mass, the one displayed on the Periodic Table, is an average of the masses of all of the isotopes. But the atomic number of all isotopes is the same.

What else can I help you with?
Element are made of atoms?
Yes, an element is made of millions of atoms with the same number of protons and electrons, but some atoms will have a slightly different number of neutrons. These different atoms are called isotopes.
What is a substance in which one or more atoms have the same number of protons or atomic number?
Element
What is an element and what is a compound?
Element consists of a single type of atom (i.e. consists of atoms with the same number of protons). Compounds are made of several different atoms.
An element which is made up of atoms?
An element is a pure substance composed of only one type of atom. These atoms have the same number of protons in their nucleus, determining the element's unique chemical properties. Examples include hydrogen, oxygen, and gold.
What are the basic particle from which all elements are made?
An atom is the basic particle of an element. Atoms are considered to be the foundation of chemistry.

An element is a substance composed of atoms that all have the same number of electrons?
No . all the atoms have same no of protones.....
What is the fundamental component of an element?
The fundamental component of an element is the atom. Each element is made up of atoms that contain a specific number of protons in their nucleus, which determines the element's unique properties.
Why can magnesium be classed as an element?
Magnesium is an element because it is made only of one time of atom, that is, all of its atoms have the number of protons.
What is an element made up of?
An element is made up of only one type of atom. Atoms of the same element have the same number of protons in their nucleus, which determines the element's chemical properties. Elements are the simplest form of matter and cannot be broken down into simpler substances by ordinary chemical means.
What it's the element gold made of?
Gold is an element made up of only one type of atom: gold atoms. These atoms are composed of protons, neutrons, and electrons. The atomic number of gold is 79, indicating that its nucleus contains 79 protons.
Which characteristic is the same for all atoms of any element?
Every element is made up of protons, neutrons, and electrons, similarly, these are all made up of quarks. All elements can also lose an electron through ionization, also referred to as the first ionization energy, although the energy required to ionize the atom is not constant.
What are elements composed of?
Elements are composed of atoms, which are made up of protons, neutrons, and electrons. Protons and neutrons make up the nucleus of an atom, while electrons orbit around the nucleus. The specific number of protons in the nucleus determines the element's identity on the periodic table.
How does a atom differ from and element?
Atoms are made of a nucleus of protons and neutrons surrounded by a clout of electrons. The electrons are negatively charged and the protons are positively charged. In every atom the number of electrons equals the number of protons so that the atom is electrically neutral. All elements are made up of atoms BUT the atom of each different element has a different number of Protons in its nucleus, for instance a Hydrogen atom has one proton and a helium atom has two protons. The elements in the periodic table are arranged in accordance with the number of protons they have, this is called their 'atomic number'.
How are elements described in terms of the atoms?
Each chemical element has atoms with a specific number of protons, different from the atoms of other elements.
