2 words you use this number to to find the number of neutrons?
Number of neutrons = Mass number - Number of protons
Consider an isotope of sodium with the mass number of 25the number of neutrons in this isotope is?
Sodium atoms always have 11 protons. Since the mass number is the sum of protons and neutrons, one can find the number of neutrons by subtracting the number of protons from this number. Thus, sodium 25 has 14 neutrons.
How you can use an atomss mass number and atomic number to determine the number of protons electrons and neutrons in the atom?
number of protons and electrons present in an element is equal to the atomic number of that element while number of neutrons is equal to mass number - atomic number/number of protons/number of electrons.
How can atomic number be used to find the numbers of protons electrons and nuetron's?
The atomic number is the number of protons and therefore, assuming the atom is neutral, the number of electrons. You would need to additionally know the atomic mass to figure out the number of neutrons.
How many protons and neutrons are found in the iodine 129 atom?
It's 53, because the number of protons equal the element's atomic number. You can easily find it on a periodic table.
How can you find the number of protons?
The number of protons is the atomic number.
How do find the number of protons?
The number of protons is equal to the number of electrons and the atomic number.
How do you find the number of protons in a neon atom?
The number of protons is equal to atomic number: neon 10 has protons.
How do you find the ratio of neutrons to protons?
You find the number of neutrons, N You find the number of protons, P Then the ratio is N:P.
The formula of neutron?
If you mean to find the amount of neutrons in an atom, you take the atomic mass and subtract the atomic number (the number of protons). That gives you the average number of neutrons.
How do you find the number of protons electrons of an element?
The atomic number of the element is the number of protons, therefore there has to be the same amount of electrons to protons.
How do you find protons in the periodic table?
# protons = atomic number.
How did you find out protons are in the nucleus?
The number of protons in the atomic nucleus is equal to atomic number.
How do you find the number of protons in an elements nucleus?
The number of protons in an elements nucleus is the same number at the atomic number.
How many moles are in Na2SO4?
just one. If you were given a mass of Na2SO4, then you could find the number of moles by dividing the mass by the molar mass(total of the mass of all elements from the mass on the periodic table). But Na2SO4 by itself is just one mole.
What is the number of protons in the nucleus of xenon?
There are 54 protons in the nucleus of xenon. You can find the number of protons of any element on the periodic table by noting the atomic number of the element. The atomic number is the same as the number of protons.
What can you find with the atomic number and mass number?
atomic number is the number of protons in the atom. mass number is protons and neutrons combined.
