Close; Mass # is the number of protons + the number of neutrons.

∙ 11y agoNo, the atomic number tells you the number of protons. The mass number tells you the number of nucleons (protons + neutrons).
Wiki User
∙ 6y agoYes, these numbers are equal.

What does an element's atomic number tell us?
The atomic number is the number of protons that the element has.
The atomic number of an atom indicates the number of?
The atomic number is the number of protons in the atom. In the case of a neutral atom (as opposed to an ion), the atomic number is also equal to the total number of electrons.
Number of protons in the nucleus?
It depends on what atom it is...If it is a Hydrogen atom, it is 1If it is a Helium atom, it is 2...Find the element you want on the Periodic Table of Elements, and there should be two numbers by that element. The smaller of the two numbers tells you the number of protons that the element has.
What is the significance of the atomic number of an element?
All elements have protons and electrons. All but hydrogen have neutrons. All elements have isotopes which vary in neutrons but have the same amount of protons as the original element. Different elements never have the same amount of protons so scientists gave these elements their "atomic number" based on the amount of protons the element has. atomic number = amount of protons.
What is the atomic number on a table that tells us how many of what are in an atom of the element?
The atomic number of an elemnt tells you how many protons are in the nucleus and therefore how many electrons thare are in a neutral atom. The mass number is the toal of protons and neutrons.
What does an element's atomic number tell us?
The atomic number is the number of protons that the element has.
What does an elements atomic number?
The Atomic number tells you the number of protons in the nucleus of atoms of that element.
What number in the nucleus makes the elements unique?
That would be the Atomic number. It tells you how many protons are contained in the nucleus of an atom. No two elements could share this number.
What tells the number of protons in the nucleus of every atom of every atom of an element?
The number of protons is also the same as the atomic number.
Why is an element's number important?
An elements atomic number is important because it tells you how many protons are in the nucleus of the atom, and how many electrons are orbiting the nucleus in the ground state.
What identifies the atom tells the number of protons in the nucleus?
The atomic number
What characteristic of an element tells the number of protons in its nucleus?
Its atomic number.
What tells you how many protons in a nucleus of an atom?
atomic number
The atomic number tells you the number?
The atomic number tells you the number of protons in the nucleus of an atom of the associated element.
The atomic number of an element tells you the number of?
The atomic number refers to how many protons in the nucleus and thus how many electrons are in orbit.
What tells the number of protons in the nucleus of every atom an element?
atomic number
What tells the number of protons in the nucleus of every atom of element?
atomic number
