How you can use the atoms mass number and atomic number to determine the number of protons electrons and neutrons in the 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.
How do scientists determine the number of neutrons and isotopes in an atom?
Atomic mass minus atomic number. This is rather simplified but the atomic mass of an element is the total of all the protons, neutrons, and electrons in an atom. Each proton and neutron has an atomic mass of approximately 1 AMU (atomic mass units) while an electron has an atomic mass of about 0.0005 AMU. So, you don't need to worry about the electrons. The atomic number of an element is simply the number of protons in the atom. So, atomic mass (number of protons and neutrons) minus atomic number (number of protons) equals number of neutrons in an atom.
What part of an atom must change for the atom to become a new element?
An atom must gain or lose protons from its nucleus to become an atom of another element. The number of protons, and to a much lesser extent the number of neutrons, will determine the chemical properties of an element.
What determines the different isotopes from an atom?
The name of the element and the mass number (number of protons + neutrons) it is written e.g Uranium-235 or symbolically 235U
What do protons determine about an element?
The protons of an element determine the atomic number, also known as the proton number. Do not confuse this with mass number which is the number of protons and neutrons.
What does the number of neutrons determine?
they determine the atomic mass of the atom
What do we do to determine the number of neutrons in a atom?
atomic number
What does the mass number determine?
The Number Of Protons & Neutrons In An Atom.
What is counted in an atom to determine mass number?
NEUTRONS AND PROTONS are counted in an atom to determine it's mass number.
How do you determine the number of nuetrons in an atom?
Number of Neutrons = Mass number - Atomic Number
What must you know about an atom to determine its mass number?
The number of protons and neutrons in its' nucleus.
How you can determine the number of protons electrons and neutrons an atom has from an atom's mass number and its atomic number?
To determine the number of protons, look at the atomic number. The number of electrons is also the atomic number.To find the number of neutrons subtract the atomic number from the Atomic Mass number.
What number is used to determine how many electrons are in a neutral atom?
The atomic number (the number of protons in the atom). Neutral charge = 0 = (number of protons - number of neutrons). Therefore, number of protons = number of neutrons
How do you determine the number of neutrons in an atom of aluminum27?
there are 24 and no it isn't too high
How do you determine the atomic mass number of any atom?
protons plus neutrons
Can the mass number of an element be used to determine the number of electrons in an atom?
No. The mass number can be used, however, to determine the number of neutrons. Electrons can only be determined by knowing the atom's charge.
If a neutral atom has a mass of 12 amu and an atomic number of 5 determine the number of protons neutrons and electrons in the atom.?
Protons: 5 Neutrons: 7 Electrons: 5
