All you need is a Periodic Table. The atomic number of an element is the number of protons in the nuclei of all of the atoms of that element. So just look for the element on the periodic table, and its atomic number is the number of protons. However, if you don't have a periodic table available, and you've been given mass number, number of neutrons, and/or the number of electrons, you can calculate the number of protons by doing the following:
mass number - no. of neutrons = no. of protons
no. of electrons in a neutral atom = no. of protons
The number of protons in an atom is the "atomic number" on the periodic table. For example, H has 1 proton, He has 2 protons, Li has 3 protons, Be has 4 protons, B has 5 protons, C has 6 protons, N has 7 protons, O has 8 protons, F has 9 protons, Ne has 10 protons, etc.
The number of protons is equal to the number of electrons and the atomic number.
The amount of protons is the atomic number. It can also be found by taking the amount of neutrons from the Atomic Mass.
The number of protons is the same as the atomic number and number of electrons.
You count them by using a radiomicroscope, or look it up on the periotic table of elements.
it is the atomic number of the element. you can find the ATOMIC NUMBER by looking usually in the top right corner of each element box on the periodic tabel
For any chemical element the number of protons is equivalent to the atomic number.
Number of protons is the atomic number.
You find the number of neutrons, N You find the number of protons, P Then the ratio is N:P.
The number of protons in an atom.
Find the atomic number. That tells you the number of protons and electrons (in a neutral atom). Then find the atomic weight. The number of protons plus the number of neutrons will equal the atomic weight. So if you know the wt. just subtract the number of protons and you will have the number of neutrons.
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.
Atomic number is equal to number of protons.
The number of protons is the atomic number.
The number of protons is equal to the number of electrons and the atomic number.
The number of protons is equal to atomic number: neon 10 has protons.
You find the number of neutrons, N You find the number of protons, P Then the ratio is N:P.
The atomic number of the element is the number of protons, therefore there has to be the same amount of electrons to protons.
# protons = atomic number.
The number of protons in the atomic nucleus is equal to atomic number.
The number of protons in an elements nucleus is the same number at the atomic number.
The number of protons in an atom.
atomic number is the number of protons in the atom. mass number is protons and neutrons combined.
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.
It is the same as the number of protons if it is a neutral atom, or the number of protons plus the charge of the ion. The number of protons is the atomic number of the element.
