Hydrogen has atomic number 1.
The number of protons in an atom of an element is equal to the number of electrons in that atom which is equal to that element's atomic number.
The atomic number of the lightest element is 1, which corresponds to hydrogen.
The atomic number of an element is equal to the number of protons contained in the atomic nucleus.
An element's atomic number, or number of protons, differentiates one element from another.
The unique number of protons in the nucleus of an atom is an element's atomic number. This identifies an element.
The unique number of protons in the nucleus of an atom is an element's atomic number. This identifies an element.
The unique number of protons in the nucleus of an atom is an element's atomic number. This identifies an element.
An atomic number is actually related to an element and not an atom. Therefore, the question is not relevant. It is NOT atoms that have an atomic number; it is the element.
The atomic number is the number fo protons in an atom's nucleus. It decides the element's position on the periodic table, as well as what the element is. No two elements have the same atomic number. As soon as the atomic number, or number of protons, changes, the element itself actually changes into a new element.
Hydrogen
the atomic number is the number of protons of an element. The atomic number specifically identifies an element. You can find it on the Periodic Table of Elements.
No, each element has a unique atomic number that corresponds to the number of protons in its nucleus. Changing the number of protons would change the element itself.
