Everything is made up of atoms. An atom is the smallest amount you have have of an Element (you find these on the Periodic Table of elements) The atom is made of a nucleus and shells. Inside the nucleus are protons and neutrons.
And in the shells are electrons.
An element with 48 neutrons would most likely be cadmium (Cd) on the periodic table. Cadmium has an atomic number of 48, which means it has 48 protons. Adding the number of protons and neutrons gives the mass number of an element.
p,n =31,38 P=31 (from Periodic Table) N= 68.926-31=37.926
To find the number of neutrons in an atom, subtract the atomic number (number of protons) from the atomic mass number (rounded to the nearest whole number). The atomic mass is generally provided in the periodic table or can be calculated as the sum of protons and neutrons.
An atom of Vanadium (V) has 23 protons since it is the 23rd element on the periodic table. To find the number of neutrons, you subtract the atomic number (23) from the atomic mass of Vanadium, which is approximately 50.94. This gives you approximately 28 neutrons in an atom of Vanadium-50 (50V).
Look it up in "periodic table of elements" You can find the number of a particular element by looking at the Periodic Table; you can also do this by counting the number of protons in the nucleus.
a modern periodic table should have the 118 elements, their atomic numbers, and their masses. to find the number of protons and electrons, they are the same as the atomic number. to find the neutrons, subtract the protons from the mass.
The number of protons in an atom is its atomic number, which you can find on the periodic table. To calculate the number of neutrons, subtract the atomic number from the atomic mass listed on the periodic table.
The number of protons in an element is equal to its atomic number, which is found on the periodic table. To find the number of neutrons, subtract the atomic number from the atomic mass of the element.
An element with 48 neutrons would most likely be cadmium (Cd) on the periodic table. Cadmium has an atomic number of 48, which means it has 48 protons. Adding the number of protons and neutrons gives the mass number of an element.
Add up all the protons and neutrons in the atoms nucleus. OR, look it up on the periodic table.
# protons = atomic number.
To find the number of neutrons in an element, subtract the atomic number (number of protons) from the atomic mass number (rounded mass of the element). The atomic number can be determined from the element's position on the periodic table.
The mass number is the number of protons plus the number of neutrons in the atomic nucleus.
You use a Periodic Table to find the group, period, and the material of the 115 elements. You can find the the number of protons/electrons on the bottom of the symbols(which is arranged in oder). You can the mass number on the VERY bottom of the element's block. You can find out the number of neutrons by subtracting the number of protons/electrons from the mass number.
Lithium-9 has exactly 3 protons, 3 electrons, and 6 neutrons. To Find the number of protons just look on your periodic table, the number usually above the element on the table or the number in bold. (3) Finding the number of neutrons is simply the number preceeding the name (9) minus the number of protons (3).
25 protons 25 electrons normally 30 neutrons but it can vary between 21 and 40.
