What particle of an atoms tells us how to find the atomic number?
the number of protons in each atom
What does one determine an atoms atomic mass?
If you mean "how does one determine an atoms atomic mass?", then the answer would be to find a periodic table of elements where the whole numbers indicate atomic number and the other indicating atomic mass. Atomic number is generally described as the number of protons in a naturally occurring atom of a given element, and the atomic mass is the number of protons + number of neutrons in an atom.
Do you count neutrons to find an atoms identity?
If by its identity you mean its atomic number, no. Neutrons only count towards the Atomic Mass Number, or AMU.
How do you find the number of protrons and electrons in an atom?
The atomic number of an element is the number of protons in its atoms. In a neutral atom, the number of protons equals the number of electrons.
What is the formula used to calculate the number of electrons when only the atomic number is given?
The number of electrons is simply the same as the atomic number, assuming the compound or element is neutral (not positive or negative). To find the number of neutrons, take the atomic mass and subtract atomic number. The number of electrons is simply the same as the atomic number, assuming the compound or element is neutral (not positive or negative). To find the number of neutrons, take the atomic mass and subtract atomic number.
What is the atomic number of atoms?
how do you find the atomic number for an element?
How do you you work out the number of neutrons in an atom?
Atomic Mass minus atomic number
What is the atom with same atomic number but different mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
How do you find the number of neutrons in an elements atoms?
number of neutrons = mass number - atomic number
What particle of an atoms tells us how to find the atomic number?
the number of protons in each atom
Can an atom of two different elements have the same mass number?
Yes. The mass number is basic to the different elements, even more useful than the atomic number. (Unless it is an isotope. Isotopes have a different amount of neutrons than the basic element atom which makes a difference in mass number too. So, a difference in mass numbers doesn't always mean it is a different element.)

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)
How do you find neutrons in an element?
In order to find the number of neutrons in the atoms of an element, you must specify the isotope that you are interested in. Isotopes are specified according to their mass number. For example carbon-12 is the isotope of carbon that has a mass number of 12, and carbon-14 is the isotope of carbon that has a mass number of 14. All atoms of the same element, regardless of mass number, have the same number of protons, which is the element's atomic number. To determine the number of neutrons in an isotope, you subtract the atomic number from the mass number. For example, the atomic number of carbon is 6, which means that all carbon atoms contain 6 protons in their nuclei. So, to find the number of neutrons in a carbon-12 atom, subtract 6 from 12, and you get 6 neutrons in the atoms of carbon-12. To find the number of neutrons in a carbon-14 atom, subtract 6 from 14, and you get 8 neutrons in the atoms of carbon-14.
How do you get number of electron of nitrogen?
Find the atomic number of nitrogen in a periodic table or other reference. (It is 7 for nitrogen.) The number of electrons in any neutral atoms is always the same as the atomic number of the atom.
How do you find the number of protrons and electrons in an atom?
The atomic number of an element is the number of protons in its atoms. In a neutral atom, the number of protons equals the number of electrons.
