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.

What element on the periodic table has 48 neutrons?
Several can. If you meant protons, then it's cadmium.
How many electrons neutrons and protons does Indium have?
So, all you have to look at is at the atomic number of the elements on the periodic table, which it is at the top of the symbol on the P.T, and that is the number of protons and electrons! Now, to find the number of neutrons, you have to find the number at the bottom of the element symbol called the atomic mass no. and you take away that by the top number.
How many protons and neutrons in N-15?
The number after the "N", 15, is the mass number. The mass number is the sum of the number of protons and the number of neutrons. So, if you find a periodic table, you can find the atomic number, which is the same as the number of protons. Because the atomic number of nitrogen is 7, it has 7 protons. Then we take the mass number (protons + neutrons) and subtract the number of protons to find the number of neutrons. 15 - 7 = 8 neutrons in 15N.
How do you find the atomic number of an element?
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.
How much protons are in oxygen?
Oxygen has 8 protons. The number of protons tell you which number the atom is in the periodic table, so you can just look at the periodic table and the element's number to find out how many protons it has.
What does a periodic table have?
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.
To find the atomic mass of an element you do what?
Add up all the protons and neutrons in the atoms nucleus. OR, look it up on the periodic table.
How do you find protons in the periodic table?
# protons = atomic number.
How do you calculate the number of neutrons an atom of a specific element has?
First, find its atomic mass on the periodic table and subtract the number of protons (element number) from it and there you go
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 do you find the mass number on the periodic table for the elements are calculated?
The mass number is the number of protons plus the number of neutrons in the atomic nucleus.
How many protons and neutrons does Li-9 have?
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).
How do you use a periodic table?
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.
How much protons neutrons and electrons does manganese have?
25 protons 25 electrons normally 30 neutrons but it can vary between 21 and 40.
How do you find the atomic number and atomic mass for an element on the periodic table?
Elements are arranged according to according to atomic number. It is the number of protons. Atomic mass is sum of protons and neutrons.
How do you find the number of neutrons in a element using only mass and the element name?
Look up the name on the periodic table and subtract the atomic number from the mass number (which is protons and neutrons). That will give you the number of neutrons.
What can we find on the periodic table?
The Periodic table is a table with more than a hundred Elements on it. As of 2010, there are 118. Along with the names of the Elements there is the chemical symbol of the Element, the atomic number, and usually the atomic mass of the Element. The atomic number represents the number of Protons in one atom, and the atomic mass is the mass of the Protons and neutrons added together. The Electrons are not added onto the mass of the Protons and Neutrons because the Electrons are negligible.
