The atomic number of an element is equal to the number of protons in the nucleus of that element; it will identify the element. The number of neutrons of a given element may be different as the element may have a number of isotopes.
The atomic number is an identifier for each chemical element.
The Atomic number
The atomic number generally. the atomic number is the number of protons(or electrons) an atom has.
The atomic number is the number of protons in the nucleus of an element. It is what determines what kind of an element it is. When you change the number of protons in the nucleus, you change the type of element.
it is unique for each element and distinguishes one element from another based on the number of protons in the nucleus. Just like how a fingerprint can identify a specific individual, the atomic number can identify a specific element in the periodic table.
Yes.
Every element has a specific number of protons, which is how an element is identified. That gives its atomic number. The number of neutrons can vary, and therefore is not useful in identifying an element.
The number of protons and electrons and hence the identity of the element too.
Yes, the number of protons is always used to identify an element. This is also known as its atomic number.
Yes
The atomic number of an element is unique to that element. The atomic number is equal to the amount of electrons in one atom of that element. As each element categorically has it's own amount of electrons, you can identify an element from this number.
The atomic number of the element would be the most helpful piece of information for identifying it, as each element has a unique atomic number that corresponds to the number of protons in its nucleus.
