What does the atomic number tell you about the atomic structure of any element?
An atom contains Protons, Neutrons and Electrons the atomic number is the protons and neutrons combined, the number of protons in the atom is equal to the total number of electrons in the atom which are aranged in the outer shells at 2,8,8,8,8 and so on to find the totoal number of protons in the neucleus of the atom you take the atomic mass and minus the atomic number from it. so He or Helium is 4.0026 atomic mass and 2 for atomic number and so has 2 protons and so in turn has 2 electrons.
Describe how to find the atomic number for the element oxygen?
Okay, here is a simple way to find the atomic number, Count the protons or if you want a more techical way. Take the total mass of the nucleus minus the mass of all the neutrons then divide the rest of the mass by the mass of one proton.
The sum of the protons and the neutrons will tell the atomic what?
Atomic mass number of the atom. The best way to remember it is: the majority of the mass of an atom is made up of the protons and neutrons (the electrons are very light!), therefore the atomic mass number is the sum of the protons and neutrons.
What determines the atomic number of a substance?
The atomic number is the number of protons in the nucleus of an atom, while the atomic mass is the total mass of the nucleus (both protons and neutrons)
What is the mass number for Fe?
The number of Neutrons and Protons in the nucleus.So it would be 26 Protons and 30 Neutrons so...26+30=56<so that is the mass number.
How do you get number of neutrons?
Atomic mass minus the atomic number.
The mass number minus the atomic number?
If you subtract the mass number by the atomic number you get the number of neutrons.
What is the difference between atomic mass unit and atomic mass?
Atomic mass unit is the number on the bottom of the Chemical. However, the atomic mass is the number on the top of the chemical minus the number on the bottom. b.t.w The no. of neutrons = top no. minus bottom no.
What does the formula atomic mass minus the atomic number equal?
By subtracting the mass number and the atomic number, the number of neutrons can be calculated.
Is The number of protons is equal to the atomic mass minus the atomic number.?
false
How can the number of proton neutron and electron be calculated to get atomic number and atomic mass?
atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number atomic number is the amount of protons, equal to the atomic number, the electrons, minus the mass number
What is the atomic mass minus the number of neutrons?
The number of protons, also called the atomic number.
How do you you work out the number of neutrons in an atom?
Atomic Mass minus atomic number
How do you get the number of protons electrons and neutrons from the atomic mass number and atomic number?
Number of protons = atomic number Number of neutrons = Atomic Mass (rounded to the nearest whole number) minus the atomic number Number of electrons in a stable element = number of protons Number of electrons in an unstable element = atomic number minus the charge
Are the number of neutrons equal to the atomic number minus the atomic mass?
false
How do you find the number of nutrons in an atom?
Find out how many protons (atomic number) and what the mass number of a particular element is. Then subtract the number of protons from the rounded mass number to get the number of neutrons in a particular atom.
What is atomic mass number minus protons?
atomic mass number - protons = number or neutrons
