How do yo find the neutrons of an atom?

Answer 1

Refer to the Periodic Table of elements

the number above the letter (atomic #) refers to the number of protons in the nucleus

NOTE: in a neutral atom, we know that #protons = #electrons

the number below the letter(Atomic Mass) refers to the number of protons + neutrons

therefore if we take

ATOMIC MASS - ATOMIC # = # NEUTRONS

Answer 2

Depends on the number of protons that atom has. In a stable atomic structure that is not radioactive this usually a 1:1 proton to neutron ratio.

==================================

Except for iron, with 26 protons and 30, 31, or 32 neutrons, all stable.

And except for chlorine, with 17 protons and 18 or 20 neutrons, both stable.

And zinc, with 30 protons and 35 neutrons.

And tin, 50 protons, 68 neutrons.

And lead ... 82 protons and 125 neutrons.

And xenon ... 54 and 77.

And Mercury ... 80 and 120.

And silver ... 79 and 118.

And the stable form of uranium ... 92 protons and 146 neutrons.

In fact, once you get past the first 20 elements or so, all the rest have more

neutrons than protons in their nucleus, and the higher you keep going, the

bigger the difference is.

Answer 3

Well.... a neutron is not known to be seen. Scientists know where a neutron is at by the research they did on it and their 5 senses. The neutron is possibly the smallest part of an atom out of a proton, an electron, and an neutron. They cant even see a neutron with one of those expensive microscopes made for atoms and things..... :) Hope this helps!!

5 senses- smell, taste, hear, see, and feel

Answer 4

One way to get the number of neutrons in an atom is by calculation :

Example :

If you have the mass of the atom and the atomic number(number of protons) :

Mass (A) - Atomic number(Z) = Number of neutrons (N)

Oxygen atom : A-Z=N

16-8=8

Thus the single oxygen atom contains 8 neutrons.

Answer 5

To calculate the amount of neutrons in an atom, subtract the Atomic # (# of Protons) from the Atomic Mass. Because electrons are virtually weightless, the remaining number will leave you with the amount of neutrons.

Ex.

Carbon

Atomic #: 6

Atomic Mass: 12

12 - 6 = 6

Therefore, there are 6 neutrons.

Unfortunately, isotopes tend to mess things up.

This is just the general rule for finding the neutrons in the normal periodic form of the element.

Answer 6

Round the atomic mass and divide it bythe atomic number

This is true I asked my teacher!!!!

Do not trust any one elses!!!!

Answer 7

You find out the neutrons by subtracting the ATOMIC MASS from the ATOMIC NUMBER.

Ex: Atomic mass: 20

Atomic Number: 5

20 (atomic number) - 5 (atomic mass) = 15 neutrons

Answer 8

You find out the neutrons by subtracting the ATOMIC MASS from the ATOMIC NUMBER.

Ex: Atomic mass: 20

Atomic Number: 5

20 (atomic number) - 5 (atomic mass) = 15 neutrons

Answer 9

To find the number of neutrons in a nucleus, we need to subtract the mass number from the atomic number.

Answer 10

Neutrons number = Mass number - Protons number
