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
Mass number = 19, Atomic number = 9
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)
The atomic number of the element is the number of protons or number of electrons in an atom of the element . The atomic weight of the element is the ratio of the mass of the atom to the 1/12th of the mass of the atom of carbon 12.
The number of electrons in an atom is always equal to the number of protons in that same atom. Since the atomic mass of a periodic element equals the weight of the atoms protons AND its neutrons, the following equation can be used to calculate the number of any given particle in an atom: number of neutrons = atomic mass - atomic number
The highest number of electrons in an atom is 116, as Ununhexium has an atomic mass of 292 it has 116 protons and 116 electrons as well as 176 neutrons.
the number of protons in an atom and the number of electrons in an atom
the Atomic Mass number is the number of protons/electrons in an atom
the Atomic Mass number is the number of protons/electrons in an atom
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
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.
The atomic mass NUMBER equals the number of protons and neutrons in an atom. DO NOT confuse this with the mass of an 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.
