What does an atomic number of 26 mean?
iron
An atom of iron has 26 protons in its nucleus; therefore the atomic number of iron is 26. An atom or a nucleus of iron (chemical symbol Fe), for example, may be written 26Fe.
Why is iron’s atomic number 26?
An atom is composed of three particles — protons, neutrons and electrons. The number of protons is the defining characteristic of an element, and this number also tells you how many electrons are present in a neutral atom. Therefore, iron — with an atomic number of 26 — has 26 protons and electrons.

How is an element assigned its atomic number?
The total number of protons present in the nucleus of an atom is known as its atomic number. For example, Nitrogen has seven protons, so its atomic number is seven. It is denoted by the letter Z of English. It is a number assigned to a particular element based on the number of protons present in its atoms.
How do you calculate atomic number of an element?
To calculate the atomic mass of a single atom of an element, add up the mass of protons and neutrons. Example: Find the atomic mass of an isotope of carbon that has 7 neutrons. You can see from the periodic table that carbon has an atomic number of 6, which is its number of protons.
What does atomic number 26 mean?
Here are all the possible meanings and translations of the word atomic number 26. a heavy ductile magnetic metallic element; is silver-white in pure form but readily rusts; used in construction and tools and armament; plays a role in the transport of oxygen by the blood
What do elements have atomic number?
What is Atomic Number? The total number of protons in the nucleus of an atom gives us the atomic number of that atom. It is represented with the letter ‘Z.’ All the atoms of a particular element have the same number of protons, and hence the same atomic number. Atoms of different elements have different atomic numbers.
