The atomic number is the number of Protons

The mass number is the number of Protons and Neutrons

The number of Electrons always equals the number of Protons

Therefore according to the above information the atomic number of the atom is 5

HOWEVER there is NO element with a mass number (atomic mass) of 9 with an atomic number of 5.

You question is impossible to answer.

Beryllium has an Atomic mass of 9.0122 and an Atomic number of 4

Boron has an Atomic mass of 10.811 and an Atomic number of 5

no the atomic mass is the mass of the element. the atomic number tells you how many protons (and electrons when the atom is neutral)


the atomic number is the number of electrons in an atom and the atomic mass is the sum of electrons and neutrons in a atom. i.e. Potassium's atomic number is 19 (19 electrons) and its atomic mass is 39 (19 electrons + 20 neutrons)


Atomic mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.


NO, the atomic number is the sum of the proton and electrons. The mass of an atom is the total mass of a motionless atom.


The atomic number of an atom is the number of protons or electrons for the atom. Its mass or atomic weight value is the total number of protons (or electrons) plus the number of neutrons.


the atomic mass number is the number of protons/electrons in an atom


the atomic number is the number of protons/electrons in the atom


Atomic mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.


Atomic mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.


Atomic mass is the number of protons plus the number of neutrons in the atom. Atomic mass cannot be the number of electrons plus neutrons, as electrons don't have the same mass.Also, there is the same amount of protons as there are electrons in an atom, and the atomic number represents the number of protons.


The atomic mass number of an atom equals the number of electrons plus protons. This is not to be confused with atomic mass.


The atomic mass NUMBER of an atom is equal to the sum of the protons and neutrons of the atom. The atomic mass of an atom is the total mass of the electrons, protons, and neutrons in a motionless atom.


The atomic mass or mass of an atom is locaed at the bottom of a sqaure on the periodic table. The atomic mass= atomic number (protons/neutrons)+electrons. Enable to find the number of electrons you must


Atomic mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.


Atomic mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.


Atomic mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.


Atomic mass NUMBER = number of protons in a nucleus + number of neutrons in the nucleus. The atomic mass of an atom is the total mass including electrons in a motionless atom.


Atomic number is the number of protons in the atom; atom mass is the total mass of the atom (usually neglecting the mass of the electrons because they have so little).


Atomic mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.


Atomic mass is the mass of an atom in atomic mass units, and includes protons, neutrons, and electrons; and atomic number is the number of protons in the nucleus of the atom.


Atomic number is the number of protons in an atom. In a neutral atom the numbers of protons and electrons are equal. So if you know the atomic number of a neutral atom, you will also know the numbers of protons and electrons. Mass number is the sum of protons and neutrons in a particular isotope of an atom. Since atomic number is the number of protons in an atom, subtract the atomic number (or number of protons) from the mass number to get the number of neutrons. Mass no. - atomic no. = no. of neutrons or mass no. - no. of protons = no. of neutrons.


The atomic number of an atom is the number of protons in its nucleus. The atomic mass is the combined mass of all protons, neutrons, and electrons in an atom of the element.


The atomic number is the number of protons in an atom (which equal the number of electrons present) The atomic mass is the number of protons+neutrons in an atom


The numbers of protons and of electrons in an atom are both the same as the atomic number, and the difference between the mass number and the atomic number is the number of neutrons in the atom.


atomic number is number of electrons or protons in an atom of an element where as atomic mass number is sum of protons and neutrons in an atom of an element
