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

How many protons electrons and neutrons does an atom with an atomic number of 50 and mass number of 125?
If its a neutral atom, there will be the same number of protons as electrons. The atomic number will tell you how many protons there are, so there are 50 protons and 50 electrons.The mass number is the sum of the number of protons (or electrons in a neutral atom) and the number of neutrons. Since we know there are 50 protons, we subtract 125 with 50 to get 75 neutrons.
What does an elements atomic number represent-?
The number of protons (or electrons) an atom has. To find out how many neutrons there are take the atomic number and subtract it from the Atomic Mass... (atomic mass)-(atomic number)= neutrons atomic number= #of protons (or #of electrons)
Does fluorine contain 10 electrons?
it has 9 electrons atomic number= number of protrons and electrons and atomic mass-atomic number=neutrons
How do you figure out how many neutrons are in a a atom?
Each nucleon (proton or neutron) contributes about 1 atomic mass unit to the mass of the atom. The mass contribution of the electrons can be ignored, since it takes about 1800 of them to equal the mass of a nucleon and the heaviest elements known have around 1/15th that number of electrons. So if you subtract the atomic number (number of protons) from the atomic mass rounded to the nearest whole number (number of nucleons), what's left is the number of neutrons.
What is the atomic number if there are 34 electrons and 50 neutrons '?
To find the atomic number, you need to subtract the number of neutrons from the total mass number of the atom. In this case, the total mass number would be 84 (34 electrons + 50 neutrons). If the atom is neutral, the atomic number would also be 34, as it would have an equal number of protons and electrons.
How you calculate the atomic mass?
the Atomic Mass number is the number of protons/electrons in an atom
How do you calculate the atomic mass?
the Atomic Mass number is the number of protons/electrons in an atom
How do you calculate the atomic mass number?
the atomic mass number is the number of protons/electrons in an atom
What do the atomic number and the mass number tell you about the atom?
the atomic number is the number of protons/electrons in the atom
What do the atomic number and mass number tell you about the atom?
the atomic number is the number of protons/electrons in the atom
Why do you calculate the number of electrons by the atomic mass and number?
You calculate the number of electrons by the atomic mass and number because elements have the same number of electrons as they do protons. The atomic number tells you the number of protons, which is also the number of electrons in a neutral atom. By using the atomic mass to find the number of neutrons, you can determine the overall charge and number of electrons in an atom.
What are the differences between atomic number and atomic mass?
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 equals the number of what?
The atomic mass NUMBER equals the number of protons and neutrons in an atom. DO NOT confuse this with the mass of an atom.
What is the difference between atomic number and atomic mass weight?
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.
What is the difference between atomic mass and atomic number?
Atomic mass refers to the total mass of an atom, including the mass of protons, neutrons, and electrons. Atomic number, on the other hand, represents the number of protons in the nucleus of an atom, which determines its chemical properties and place on the periodic table.
Is atomic number the same as mass number?
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).
What is difference between atomic weight and atomic mass?
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.
